INTRODUCTION
This document officially revises all previous highway mobile source
emission factors (AP-42) documents. This document includes information
on particulate emissions, and diesel powered vehicle and truck emission
factors. Further, this document will be periodically revised as the
emissions and in-use vehicle operational characteristics vary from those
presented. This document also summarizes the detailed background
document which describes the data and derivation process for all the
emission factors contained herein. As such, the only specific reference
for this document is as follows:
Derivation of the Highway Mobile Source Emission Factors, April
1981, EPA 460/3-81-007.
A. PURPOSE
This document was generated to present more recent emission factor
information for highway mobile sources. As such, the March 1978 Mobile
Source Emission Factors; For Low-Altitude Areas Only, EPA-400/9-78-006
and Mobile Source Emission Factors, EPA-400/9-78-OQ5 (MSEF) documents are
outdated.
B. MAJOR DIFFERENCES FROM 1978 MSEF
The differences between the emission factors presented in this document
and the March, 1978, MSEF documents are numerous. The differences are
listed below:
1) Calculation Methodologies
a) The emission factors are calculated for a January 1 date
instead of a July 1 date.
b) Crankcase and evaporative HC emissions are given by
component (crankcase, diurnal, and hot soak losses).
c) A single speed correction factor is now applied to the
entire trip cycle. Previously, a speed correction factor
was applied to each of the three operating modes.
d) Temperature effects are evident on all three pollutants
and operating modes as opposed to only HC and CO during
the cold start mode.
e) The use of air conditioning is a function of a discomfort
index as opposed to an estimate.
f) The HDV power to displacement emission correction factor
is no longer available.
g) A different approach is used to estimate the future in-use
vehicle fleet emissions.
2) Emission Data
a) Particulate emissions are included.
xi
-------
b) Emissions for two new vehicle types, LDDV and LDDT, are
included.
c) The HDV emissions are based on the transient cycle test
procedure.
d) More evaporative HC emission data are included.
e) More basic exhaust emission data for every vehicle type
are incorporated, usually for the latest model years and
across wider mileage range.
f) Additional idle emissions data for every vehicle type are
used.
g) More current travel weighting fraction data (registration
mix and mileage accrual) for each vehicle type are used.
h) New non-methane HC data are included.
i) More temperature correction factor data for light duty
gasoline powered vehicles are incorporated.
j) New data for air conditioning effects on emissions are
utilized.
3) Regulations
The emission rates for the 1981 and later model year vehicles
reflect the emission standards and regulations that were
projected at the time of this update.
In summary, all of the changes have an impact on the calculated emission
factors. To illustrate the differences, nine figures are given. Each
figure represents emissions at an average speed of 19.6 mph, a
temperature of 75°F, and operating mode VMT percentages of 20.6% for cold
start and 27.3% for hot start. The nine figures are grouped into three
sets: 1) low altitude non-California, 2) California, and 3) high altitude
non-California emissions for January 1 of calendar years 1970 through
1999. The figures represent the emission levels for all eight vehicle
types combined. Each set of graphs is composed of the three pollutants:
non-methane HC, CO, and NOx. The emissions predicted by the 1978 MSEF
methodology were generated by the MOBILE1 computer model. The emissions
predicted by the 1981 'AP-42 methodology were generated by the MOBILE2
computer model.

C. DOCUMENT ORGANIZATION
This document presents the highway mobile source emission factors in
three major parts. These three parts refer to the three regions of the
country: 1) low altitude non-California, 2) California, and 3) high
altitude non-California regions.
Each part presents highway mobile source emission factors for eight
vehicle types. The eight vehicle types are 1) light duty gasoline
powered vehicles (LDGV), 2) light duty gasoline powered trucks with gross
vehicle weight (GVW) less than 6,001 Ibs. (LDGTl), 3) light duty gasoline
powered trucks with GVW less than 8,501 Ibs. but greater than 6,000 Ibs.
(LDGT2), 4) heavy duty gasoline powered vehicles (HDGV), 5) light duty
diesel powered vehicles (LDDV), 6) light duty diesel powered trucks
(LDDT), 7) heavy duty diesel powered vehicles (HDDV), and 8) motorcycles
(MC). Light duty vehicles and automobiles are synonymous.
Chapters 1 through 8 present the emission factors for the low altitude
non-California vehicle types. Each of these eight chapters is divided
into four sections: 1) Introduction, 2) Emissions, 3) Travel Weighting
Fractions, and 4) Emission Correction Factors. The first section defines
the vehicle type, the basic exhaust emissions test procedure, and the
generalized equations for calculating emission factors. The second
section presents the basic exhaust emission rates, crankcase and
evaporative HC emission levels, January 1 basic exhaust emission levels,
and idle exhaust emission rates. The third section details the
distribution information required for the travel weighting fractions.
The last section explains how the basic exhaust emissions are corrected
for various ambient and vehicle usage conditions. Chapter 9 presents the
emission factors for the California vehicle types. The emission factors
for the high altitude non-California vehicle types are presented with
Chapter 10. The tables referenced in each of these ten chapters are
given in Appendix E.
In addition to the ten chapters, seven appendices are given with this
document. Appendix A presents the emission standards assumed in this
document. Appendix B illustrates how the total vehicle-miles-traveled by
the highway mobile source fleet is apportioned among the individual
vehicle types. Appendix C gives the calculation procedure used to
combine the emissions of the two light duty gasoline powered truck
classes. Appendix D presents the methodology for calculating the travel
weighting fractions and the mileage accumulation distribution for each
vehicle type. Appendix E presents the emission factor tables for each
vehicle type and region. Appendix F gives an example on how to calculate
the emission factors. Appendix G presents emission levels of all
vehicles combined under various ambient and usage conditions.
Computing the emission factors is complex and time consuming. It is
recommended that a computer program be used to calculate the emission
factors. The EPA has developed a computer program, MOBILE2, that will
perform the calculations using the emission factors presented in this
document. The MOBILE2 computer program and user's guide can be obtained
from the National Technical Information Service (NTIS), U.S. Department
of Commerce, Springfield, VA 22161 (PB81 223067). Phone: (703) 487-4650.

D. VEHICLE INSPECTION AND MAINTENANCE PROGRAM
If an annual motor vehicle inspection and maintenance (I/M) program is in
effect in the area for which emission factors are being calculated,
emission reduction credits can be taken.
The methodologies for determining the I/M credits are contained in the
Derivation of I/M Benefits for Pre-1981 Light-Duty Vehicles for Low
Altitude, Non-California Areas,EPA-IMS/81-4andDerivation of I/M
Benefits for Post-1980 Light Duty Vehicles for Low Altitude,
Non-California Areas, EPA-AA-IMS/81-2.The MOBILE2 computer program can
apply these low altitude non-California I/M credits to the emission
estimates.
The emission reduction credits attributable to an annual I/M program vary.
according to the type of program in effect. The MOBILE2 credits of an
I/M program depend upon the following six factors.
1) The estimated first year failure rate (stringency factor) for
the pre-1981 low altitude non-California LDGVs (or other vehicle
types with similar emission control technologies). The pre-1975
vehicles are labeled Technology I vehicles and 1975-1980
vehicles are labeled Technology II vehicles.
2) The success rate in identifying 1981 and later model year low
altitude non-California LDGVs operating under rich failure
conditions (the identification rate of Technology IV vehicles).
Technology III is not defined in MOBILE2.
3) The vehicle types affected by the I/M program: LDGV; LDGV &
LDGT1; LDGV & LDGT2; or LDGV, LDGT1, & LDGT2.
4) The calendar year being analyzed and the calendar year the I/M
program is implemented.
5) The presence or absence of an adequate mechanics training
program.
6) The model years involved in the I/M program.
E. REACTIVE VS. NON-REACTIVE HYDROCARBON EMISSIONS
Available scientific evidence indicates that methane and a few other
non-reactive organic compounds do not contribute significantly to ozone
formations. EPA1s Volatile Organic Compound policy, published in the
Federal Register on July 8, 1977, allows a limited number of compounds,
including methane, to be excluded from control actions. States have been
advised that they should exclude these compounds from baseline emission
inventories that are to be used for control strategy development for
ozone.
Although motor vehicles are regulated directly by the Clean Air Act on a
total hydrocarbon basis (rather than on a "reactive" hydrocarbon basis),
it is appropriate, when estimating ozone levels, to consider only those
motor vehicle emissions which will react to form ozone. However7'
consideration must be given to the format of any associated stationary
source emission inventory so that mobile source and stationary source
emission inventories are consistent in their exclusions.
xxiii
-------
Prior to the introduction of catalyst technology, virtually all (93% or
greater) mobile source HC emissions were considered reactive.' With
present and future catalyst technology, the methane (i.e., non-reactive)
fraction of total hydrocarbon emissions is Increasing. Estimates of the
methane percentages applicable to each vehicle category are given in
Table 1.
While the MOBILE2 computer program can calculate either total or
non-methane hydrocarbon emissions, all HC emission factors presented in
this document are total hydrocarbons.

F. PARTICULATE EMISSIONS
The particulate emissions for total exhaust, lead, sulfate, and tire
particulates are presented in Table 2 for all low altitude and California
vehicle/technology types. Similarly, the particulate emission factors
for high altitude vehicle/technology types are presented in Table 3.
Where applicable, total exhaust particulate from non-catalyst vehicles
using leaded gasoline is normalized to. 2.0 grams/gallon Pb. Further,
taking an intermediate value from experimental data, we assume lead
particulate to be 30% of total exhaust particulate as measured over the
FTP urban cycle from non-catalyst vehicles using leaded gasoline. This
assumption is consistent with calculations based on fuel lead content,
vehicle fuel economy, and percent total lead emitted as particulate.
No information is available on total exhaust particulate from HDGV using
unleaded gasoline. As a result, the emission factor is estimated by the
following:
Total ExhHDGV(Unleadedj - Total Exhu^d^,.^,,,!) Total Exh HDV (Leaded)
Total ExhLDV(Leaded)
" 32 (420) - 56 mg/mile
240
No measured data could be found on total exhaust, lead, sulfate, and tire
particulate emissions from light duty gasoline powered trucks (LDGT).
Based on engineering Judgement that the differential in average weight
and average fuel economy between LEGTs and LDGVs is minor and that the
two vehicle classes are similar within individual technology subgroups,
it is assumed that LDGT particulate emission factors are equal to those
of LDGVs.
For light duty diesel powered trucks (LDDT), the limited data available
indicates no difference in exhaust particulate levels between LDDTs and
LDDVs. Furthermore, exhaust particulate standards for LDDVs and LDDTs to
be imposed on 1982 through 1984 model years are identical and roughly
equivalent to currently measured levels. it is therefore assumed that
th.e standard will be met, and the standard is selected as the appropriate
emission factor for all model years through 1984. For 1985 and later
model years, it is similarly assumed that the reduced standards for LDDVs
and LDDTs will be met, and these are taken as the applicable emission
factors.
The tire wear rate of 0.085 grams/mile/tire estimated for LDVs is assumed
for all vehicle types due to lack of data. Tire particulate is then
computed by vehicle type based on the average number of wheels and the
estimate that 55% of the tire wear becomes suspended particulate.
Total exhaust particulates from all diesel powered vehicles at high
altitude are estimated to increase by 39% over the levels at low
xxv
-------
altitude. Sulfate levels at high altitude are estimated to decrease by
68% over the levels at low altitude. Due to insufficient data, all other
particulate emission factors at high altitude are assumed equal to low
altitude factors.

Chapter 1
LIGHT DUTY GASOLINE POWERED VEHICLES
l.A INTRODUCTION
Because of their widespread use, light duty gasoline powered vehicles
(LDGV; passenger cars) are responsible for a large share of air pollutant
emissions in many areas of the United States. A LDGV is defined to be
any gasoline fueled motor vehicle designated primarily for transportation
of persons and having a capacity of 12 persons or fewer. Substantial
research effort has been expended to accurately characterize emissions
from these vehicles. EPA's on-going program to collect in-use vehicle
emissions was instituted a number of years ago in order to estimate
emission levels.
In addition to the methodologies presented for calculating the basic
exhaust emission levels for HC, CO, and NOx, data are given in this
chapter for crankcase and evaporative hydrocarbon emissions, and
emissions in the idle mode. Information is also given regarding the
emission correction factors and travel weighting fractions.
I.A.I Test Procedure
LDGV emissions testing is currently performed according to the procedures
stipulated in the Federal Register (42 FR 32954, June 28, 1977) and the
Code of Federal Regulations (40 CRF Part 86, Subpart B, July 1, 1980).
The basic test conditions under which the LDGVs are tested are as follows:
1. Ambient temperature range is 68°F to 86°F.
2. Absolute humidity is adjusted to 75 grains of water per pound of
dry air.
3. Average speed is 19.6 mph with 18% idle operation.
4. Average percent of vehicle-miles-traveled (VMT) in a. cold start
operation is 20.6%.
5. Average percent of VMT in a hot start operation is 27.3%.
6. Average percent of VMT in the stabilized operation is 52.1%.
7. Average trip length is 7.5 miles.
Additional elements regarding the test procedure that are reflected in
the emission estimates are as follows:
1. Air conditioning not in use.
2. Car contains driver and passenger no additional passengers,
luggage, etc.
3. Car is not pulling a trailer.
The test sequence for LDGVs is summarized below:
1. Determine the weight of the vehicle.
2. Determine the road-load (assuming level road, no curves, no wind)
which is a function of weight and frontal area.
-------
-2-
3. Precondition the vehicle (i.e., vehicle is briefly driven).
4. Place the vehicle in an ambient temperature environment between
68°F and 86°F with its engine off for at least 12 hours.
5. Push the vehicle onto a dynamometer.
6. Start the engine and begin collecting exhaust emissions.
7. Emissions for the first 505 seconds are collected for test
segment #1. The mileage driven is 3.59 miles with an average
speed of 26 mph. This is the cold start portion of the test.
8. Test segment #2 collects emissions for the next 870 seconds. The
engine is not turned off between Steps 7 and 8. The mileage
driven is 3.91 miles and the average speed is 16 mph. This is
the stabilized portion of the test.
9. The engine is turned off.
10. The engine remains off for 10 minutes.
11. The car is restarted, the first 505 seconds are rerun, and
emissions are collected for test .segment #3. This is the hot
start portion of the test.
12. The grams of each pollutant are determined for each test segment.
13. NOx emissions are adjusted for humidity.
14. The basic exhaust emission level in grams per mile is computed.
1.A.2 General Emissions Calculation Equations

emission factors:
(a) BEFnpstwx - SUMi(BERipn * [NMi] * TFin * Ripstwxn * [ACCFipt *

This section discusses the emission estimates for the LDGVs: Basic
exhaust emission rates, crankcase and evaporative RC emission levels,
January 1 basic exhaust emission levels, and idle exhaust emission
rates. The emission standards are given in Section A.1.1 of Appendix A.
The emissions reflect vehicles which have received typical in-use
maintenance. Further, the vehicles are not involved in an I/M program.
I.B.I Basic Exhaust Emission Rates
The basic exhaust emission rates for LDGVs were derived for the most part
from in use vehicle data. The basic assumption in the derivation of the
emission rates is that emission levels change linearly as vehicles
accumulate mileage. The rates are dependent upon two estimated
variables: (1) zero mile emission levels and (2) the emission
deterioration rates. The zero mile emission levels are the average grams
of pollutants emitted by the vehicles at zero miles. The emission
deterioration rates adjust the zero mile levels as vehicles accumulate
mileage.
The basic exhaust emission levels are calculated from a linear function:
BERipn - ZMLip + DRip * Mln
where the lower case letters are subscripts and
-------

BERipn " The basic exhaust emission level, in grams/mile, for
model year 1 and pollutant p, on January 1 of calendar
year n.
ZMLip = The estimated zero mile emission level, in grams/mile,
for model year i and pollutant p.
DRip ° The estimated emission deterioration rate, in grams/mile/
10,000 miles, for model year i and pollutant p.
Min = The model year i cumulative mileage, divided by 10,000
miles, on January 1 of calendar year n.
The basic exhaust emission rates are presented in Table 1.1.1A for the
different LDGV model year groups and pollutants.
1.B.2 Crankcase and Evaporative HC Emission Levels
In addition to the basic exhaust HC emission levels, crankcase and
evaporative HC emissions need to be included. Crankcase HC emission
levels result from the crankcase as the engine is running. The two major
sources of evaporative HC emissions are hot soak and diurnal losses. Hot
soak losses are generally produced as fuel evaporates from the carburetor
system at the end of a trip. Diurnal changes in ambient temperature
result in expansion of the air-fuel mixture in a partially filled fuel
tank. As a result, gasoline vapor is expelled into the atmosphere.
Crankcase and evaporative HC emission levels are calculated according to
the following equation:
CCEVi = (HSKi * TPD + DNLi)/MPD + CCi
where the lower case letters are subscripts and.
CCEVi = The estimated crankcase and evaporative HC emission
level, in grams/mile, for model year i.
HSKi = The estimated hot soak HC emission level, in grams/trip,
for model year i.
TPD = The average number of trips/day.
DNLi = The estimated diurnal HC emission level, in grams/day,
for model year i.
MPD = The average miles driven per day.
CCi = The estimated crankcase HC emission level, in grams/mile,
for model year i.
Crankcase and evaporative HC emission levels are summarized in Table
1.1.IB. This table presents each variable described above for every
model year.
-------
-5-
1.B.3 January 1 Basic Exhaust Emission Levels
The basic exhaust emission levels for the latest 20 model years on
January 1, 1970 through 1993, are given in Tables 1.1.2A through 1.1.2C
for HC, CO, and NOx, respectively. The HC basic exhaust emission levels
reflect total, rather than non-methane, HC emissions and exclude
crankcase and evaporative HC emission levels.
l.B.A Idle Exhaust Emission Rates (Hot Stabilized)
Estimates of emissions expelled from the automotive fleet during a
vehicle's idle operating mode have become a major concern in
transportation control plans, environmental impact statements, and state
implementation plans. Examples of extended idle time are waits at
shopping centers, airports, sport complexes, and drive-in window service
businesses. The emission estimates presented in this section reflect
engines operating in a hot stabilized condition.
The idle exhaust emission rates are expressed in units of emissions per
unit time (grams per minute) as opposed to the basic exhaust emission
rate units (grams per mile). The LDGV idle exhaust emission levels are
calculated from the estimated zero mile emission levels and emission
deterioration rates given In Table 1.1.3. The idle emission level (in
units of gm/min) is calculated from a linear function similar to the
basic exhaust emission level function given in Section I.B.I. The idle
emission function is lERipn - ZMLIDLip + DRIDLip * Min. The definition
of the terms in this equation are almost identical to those in Section
I.B.I, except these are idle emissions and are expressed in grams/minute
for the zero mile levels and grams/minute/10,000 miles for the idle
emission deterioration rates.
l.C TRAVEL WEIGHTING FRACTIONS
The LDGV travel weighting fractions are the individual model year
proportions of the total LDGV VMT. To generate the travel weighting
fractions, three distributions, described in detail below, are required:
(1) the fleet annual mileage accumulation'rate distribution, (2) the
registration distribution, and (3) the estimated fleet sales fraction
distribution (to account for the proportional increase of diesel powered
vehicles).
The travel weighting fractions in this document reflect a January 1
evaluation date. For the LDGVs, the model year is assumed to begin sales
on the October 1 preceding, the corresponding calendar year. Further, it
is assumed th»~ the vehicles are sold and accumulate mileage according to
a uniform distribution (see below). These assumptions permit the
estimation of the January 1 fleet mileage accumulation rate distribution
and the January 1 registration distribution from July 1 information. An
example of the travel weighting fraction calculation is given in
Table 1.1.5'.
-------
-6-
l.C.l Fleet Annual Mileage Accumulation Rate Distribution
A given vehicle is estimated to travel according to the annual mileage
accumulation distribution given in Table 1.1.4A. For example, the
vehicle in its first year travels 14,440 miles at a uniform rate. In its
second year, it travels 13,900 miles at a uniform rate. Finally in its
20th year, it travels 4,300 miles at a uniform rate..
The annual fleet mileage accumulation rate distribution is derived from
the annual mileage accumulation rate distribution for individual
vehicles. This derivation averages out the effects of purchase date.
The derivation is described in Appendix D, and the resulting distribution
is given in Table 1.1.4A.
l.C.2 Model Year Registration Distribution
Table 1.1.4A also presents the estimated LDGV model year registration
distribution fractions. These fractions are the individual model year
proportions of the entire LDV fleet (both gasoline and diesel powered
vehicles combined). The registration distribution is based on July 1
figures and is transformed to January 1 figures according to the
procedure in Appendix D. The January 1 LDV fleet registration
distribution is presented in Table 1.1.4A.
l.C.3 Fleet Sales Distribution
Assuming that diesel powered vehicles will become more prominent, the
travel weighting fractions need to account for them. It is estimated
that gasoline powered vehicles will account for proportionately fewer of
the future light duty vehicle model year sales according to the
distribution given in Table 1.1.4B. The distribution is anticipated to
stabilize in 1991, with 80 percent of the _LDV sales being gasoline
powered vehicles.
The fleet sales distribution is used in the travel weighting fractions to
account for the influx of diesel. The travel weighting fractions change
every January 1 in calendar years 1975 through 2010. Prior to 1975,
diesels are considered to be an insignificant proportion of the LDV
fleet. Further, even though the fleet sales distribution is predicted to
stab'lize in 1991, the travel weighting fractions require 20 years to
stabilize. From that time on (201CH-), the travel weighting fractions
remain constant.
l.D EMISSION CORRECTION FACTORS
The LDGV basic exhaust emission levels are based on test results under
the standardized conditions defined in Section I.A.I. However, the basic
exhaust emission levels are affected by ambient and vehicle usage
conditions which differ from the prescribed test procedure. The
conditions under which emissions are known to vary are the average speed,
ambient temperature, fraction of VMT in cold and hot start operating
modes, use of air conditioning, carrying of an extra load, trailer
towing, and humidity. Emission correction factors are available to
compensate for these conditions.
-------
-7-
l.D.l Speed Correction Factor
The test procedure used for collecting the basic exhaust emissions is a
driving cycle with an average speed of 19.6 nph. For those situations
where the average speed of the vehicle deviates from this value, a speed
correction factor is applied. This speed correction factor will now be
examined and later incorporated into the' Ripstwxn correction factor in
Section l.D.3.
The speed correction factor is given in Table 1.1.6. It is symbolized as
SCFipsxw where the lower case letters are subscripts and
SCFipsxw » The speed correction factor for model year i and
pollutant p at the average speed of s. This is
normalized to the speed associated with a cold start mode
VMT fraction x and a hot start mode VMT fraction w»
The user is cautioned that this correction factor is only valid for
speeds in the 5 through 55 mph range since the regression equations were
based on speed data in that range. Extrapolations to speeds beyond this
range should not be made.
1.D.2 Emission Temperature Correction Factor
The established LDGV emissions test procedure requires an ambient
temperature between 68°F and 86°F. For situations which differ from this
temperature range, an emission temperature correction factor is applied.
The emission temperature correction factors were based upon data from
several in-use vehicle emission test programs: EPA, Bureau of the Mines,
Bartlesville Energy Research Center, Canadian Environmental Sevices, and
Gulf Research. Analysis of the data indicate that all three pollutants
(HC, CO, and NOx) in all three test segments (bags) are affected by
temperature. Therefore, a separate emission temperature correction
factor is given for each bag and pollutant in Table 1.1.7A. The emission
temperature correction factor equation is as follows:
TCFipbt - EXP(TCipbtt(T - TT))
where the lower case letters are subscripts and
TCFipbt ° The emission temperature correction factor for model year
i, pollutant p, test segment b, and ambient temperature t«
EXP = The exponential function.
TCipbtt = The temperature correction factor coefficient for model
year i, pollutant p, test segment b, and reference
temperature tt.
T " Ambient temperature (Fahrenheit).
TT = Reference temperature which equals 67.5°F when T is less
than 68°F and equals 86.5°F when T is greater than 86°F.
-------
-8-
1.D.3 Speed/Temperature/Operating-Mode Emission Correction Factor
A single emission correction factor called Ripstwxn adjusts for speed,
temperature, and hot/cold start operating-mode conditions that differ
from the basic test procedure. A vehicle will usually emit more
emissions in a cold start mode than in a stabilized or a hot start mode.
As such, vehicles will emit more pollution after an extended engine off
period than vehicles that have not set long enough to be in the cold
start mode. As a result, the operating mode is a necessary element of
this correction factor.
An integral part of the operating mode portion of Ripstwxn is the
normalized bag fractions. The normalized bag fractions adjust Ripstwxn
for emissions attributable to each operating mode. These fractions for
LDGVs are given in Table 1.1.7B.
The Ripstwxn correction factor is defined as follows:
Ripstwxn = ((TERM1 + TERM2 + TERM3)/DENOM)*SCFlpswx
where the lower case letters are subscripts and
Ripstwxn = The speed/temperature/operating-mode emission correction
factor for model year i, pollutant p, average speed s,
ambient temperature t, fraction of VMT in a cold start
operating mode w, and fraction of VMT in a hot start
operating mode x; on January 1 of calendar year n.
TERM1 = W * TCFiplt *(Bipl + Dipl * Min)
TERM2 = (l-W-X)*TCFip2t * (Bip2 + Dip2 * Min)
TERM3 = X * TCFip3t *(Bip3 + Dip3 * Min)
DENOM = BipO + DipO * Min
SCFipswx = The emission speed correction factor for model year i and
pollutant p at the average speed of s, normalized to the
speed associated with a cold start mode VMT fraction x
and a hot start mode VMT fraction w.
Bipb = The normalized bag fraction intercept coefficient for
model year i, pollutant p, and test segment b (test
segment 0 is the entire basic test procedure).
Dipb = The normalized bag fraction slope coefficient for model
year i, pollutant p, and test segment b (test segment 0
is the entire basic test procedure).
Min = The fleet cumulative mileage for model year i on
January 1 of calendar year n.

The fraction of VMT traveled in the cold start mode.
The fraction of VMT traveled in the hot start mode.
TCFipbt The emission temperature correction factor for model year

1.D.4 Air Conditioning Correction Factor
The LDGV emissions can be significantly affected by the use of air
conditioning. The air conditioning correction factor coefficients are
based on data from vehicles tested at several different temperatures with
the air conditioner on. These correction, factors are given in Table
1.1.8A. The general correction factor equation is as follows:
ACCFipt - U*Vi ([Aip + Bip * (T - 75)] -1) +1
where the lower case letters are subscripts and
ACCFipt .The air conditioning correction factor for model year i,
pollutant p, and ambient temperature t.
U - (DI - DILO)/(DIHI - DILO) - Of the vehicles equipped with
an air conditioner, the estimated fraction that have it
in use (
-------
-10-
1.D.5 Extra Load Correction Factor
The basic exhaust emission rates are based on the "typical" vehicle
weight with a driver and passenger, vehicle fuel, and other liquids.
There are, however, situations in which vehicles have extra weight due to
additional passengers, luggage, etc. In these events, emissions are
known to change.
To apply the vehicle extra load correction factor found in Table 1.1.9 to
a specific situation, it is necessary for a user to have an estimate of
the percentage of LDGV VMT accumulated with an additional 500 pounds.
The correction factor for extra load is computed according to the
following equation:
ELCFip > (XLCip -1) * U + 1
where the lower case letters are subscripts and
ELCFip = The extra load correction factor for model year i and
pollutant p.
XLCip = The extra load correction factor coefficient for model
year i and pollutant p.
U The fraction of LDGV VMT accumulated with an extra load
1.D.6 Trailer Towing Correction Factor
As with the extra load correction factor, the trailer towing correction
factor will adjust LDGV emissions for usage conditions which differ from
the basic test procedure. It has been determined that towing a trailer
will affect a vehicle's emissions. As such, a correction factor is
available to adjust LDGV emissions when a trailer is being towed. The
correction factor coefficients given In Table 1.1.10 are valid for a
trailer weight of 1000 pounds. This correction factor is computed by the
following equation:
TTCFip - (TTCip - 1) * U + 1
where the lower case letters are subscripts and
TTCFip The trailer towing correction factor for model year i and
pollutant p.
TTCip - The trailer towing correction factor coefficient for
model year i and pollutant p.
U = The fraction of LDGV VMT accumulated while towing a
trailer (0<=lk=l).
-------
-11-
1.D.7 NOx Humidity Correction Factor
The NOx emission factors are normalized to 75 grains of water per pound
of dry air. In order to adjust NOx emissions to different humidity
conditions, a multiplicative correction factor is available. The formula
for the correction factor is given below, and is applicable for all model
years:
HCF - 1.0 - .0047 * (H - 75)

LIGHT DUTY GASOLINE POWERED TRUCKS I
2.A INTRODUCTION
This chapter presents the emission factors for light duty gasoline
powered trucks with a gross vehicle weight (GVW) rating of 6,000 pounds
or less (LDGT1). A LDGT1 is defined to be any gasoline fueled motor
vehicle designed primarily for transportation of property and rated at
6,000 pounds GVW or less. Although LDGTls have a load carrying
capability that exceeds that of passenger cars, they are typically used
for personal transportation; as passenger car substitutes.
As with Chapter 1, this chapter divides the emission factors into three
major sections: (1) Emissions, (2) travel weighting fractions, and (3)
emission correction factors.
2.A.I Test Procedure
The test procedure used for determining the LDGTl basic exhaust emissions
is almost identical to the LDGV test procedure. The difference between
the two test procedures is primarily the road-load horsepower setting.
The summary of the test procedure in Chapter 1 is correct for LDGTls.
Therefore, refer to Chapter 1 for a brief overview.
2.A.2 General Emissions Calculation Equations
The generalized calculating equations presented in Chapter 1 are also
valid for the LDGTls. Although the emissions, travel weighting
fractions, and emission correction factors levels for LDGTls are
different from the LDGVs, all of the equations are identical.
2.B EMISSIONS
This section discusses the LDGTl emission estimates: Basic exhaust
emission rates, crankcase and evaporative HC emission levels, January 1
basic exhaust emission levels, and idle exhaust emission rates. The
emission standards are given in Section A.1.2 of Appendix A. The
emissions reflect trucks which have received typical in-use maintenance.
Further, the trucks are not involved in an I/M program.
The discussions of the different emissions in Chapter 1 are also valid
for the LDGTls. Therefore, the discussions will not be reiterated.
Please refer to Chapter 1 for the discussions that correspond to the
subsections below.
2.B.I Basic Exhaust Emission Rates
The LDGTl basic exhaust emission rates are given in Table 1.2.LA. This
table presents the LDGTl zero mile emission levels and emission
deterioration rates for every model year. The emissions are measured in
grams per mile.
-------
-13-
2.B.2 Crankcase and Evaporative HC Emission Levels
The LDGT1 crankcase and evaporative RC emission levels are presented in
Table 1.2.IB. This table presents the emissions for every model year and
crankcase and evaporative HC component: diurnal losses, hot soak losses,
and crankcase losses.
2.B.3 January 1 Basic Exhaust Emission Levels
January 1, 1970 through 1993, LDGTl basic exhaust emission levels are
given in Tables 1.2.2A through 1.2.2C for HC, CO, and NOx, respectively.
The HC basic exhaust emission levels reflect total, rather than
non-methane, HC emissions and exclude crankcase and evaporative HC levels.
2.B.4 Idle Exhaust Emission Rates (Hot Stabilized)
The LDGTl hot stabilized idle exhaust emission rates are given in Table
1.2.3. These emission levels are measured in grans per minute and
reflect engines operating in a hot stabilized condition.
2.C TRAVEL WEIGHTING FRACTIONS
The LDGTl travel weighting fractions are the individual model year
proportions of the total LDGTl VMT. To generate the travel weighting
fractions, three distributions are required: (1) the fleet annual mileage
accumulation rate distribution, (2) the registration distribution, and
(3) the estimated fleet sales fraction distribution (to account for the
proportional increase of diesel powered trucks). The first and second
distributions are given in Table 1.2.4A, and the third distribution is
given in Table 1.2.4B. More detailed information is available in Chapter
1 on these distributions.
The travel weighting fractions in this document reflect a January 1
evaluation date. For the LDGTls, the model year is assumed to begin
sales on the October 1 preceding the corresponding calendar year.
Further, it is assumed that the trucks are sold and accumulate mileage
according to a uniform distribution. These assumptions permit the
estimation of the January 1 fleet mileage accumulation rate distribution
and the January 1 registration distribution from July 1 information. An
example of the travel weighting fraction calculation is given in
Table 1.2.5.
2.D EMISSION CORRECTION FACTORS
The LDGTl basic exhaust emission levels are based on test results under
the standardized conditions defined in Chapter 1. However, the basic
exhaust emission levels are affected by ambient and truck usage
conditions which differ from the prescribed test procedure. The
conditions under which emissions are known to vary are the average speed,
ambient temperature, fraction of VMT in cold and hot start operating
modes, use of air conditioning, carrying of an extra load, trailer
towing, and humidity level. Emission correction factors are available to
compensate for these conditions.
-------
-14-
The LDGTls correction factors are based on the LDGV information.
Therefore, the LDGT1 correction factors are those from the LDGV's, and
the LDGV discussions in Chapter 1 are valid for the LDGTls.
2.D.I Speed Correction Factor
The test procedure used for collecting the basic exhaust emissions is a
driving cycle with an average speed of 19.6 mph. For those situations
where the average speed of the truck deviates from this value, a speed
correction factor is applied. The LDGT1 speed correction factor is given
in Table 1.2.6.
2.D.2 Emission Temperature Correction Factor
The established LDGT1 emissions test procedure requires an ambient
temperature between 68°F and 86°F. For those situations where the
ambient temperature is not in this range, an emission temperature
correction factor is applied. Table 1.2.7A presents this correction
factor for the LDGTls.
2.D.3 Speed/Temperature/Operating-Mode Emission Correction Factor
A single emission correction factor called Ripstwxn adjusts for speed,
temperature, and operating-mode conditions that differ from the basic
test procedure. As described in Chapter 1, Ripstwxn depends on
normalized bag fractions. The LDGT1 normalized bag fractions are given
in Table 1.2.7B.
2.D.4 Air Conditioning Correction Factor
The LDGT1 emissions can be significantly affected by the use of air
conditioning. These correction factors are given in Table 1.2.8A. The
fractions of LDGTls equipped with an air conditioner, by model year, are
given in Table 1.2.8B.
2.D.5 Extra Load Correction Factor
The basic exhaust emission rates are based on the "typical" truck weight
with a driver and passenger, fuel, and other liquids. There are,
however, situations in which trucks have extra weight due to additional
passengers, luggage, load, etc. In these events, emissions are known to
change.
To apply the truck extra load correction factor found in Table 1.2.9 to a
specific situation, it is necessary for a user to have an estimate of the
percentage of LDGTl VMT accumulated with an additional 500 pounds.
2.D.6 Trailer Towing Correction Factor
As with the extra load correction factor, the trailer towing correction
factor will adjust LDGTl emissions for usage conditions which differ from
the basic test procedure. The correction factor coefficients given in
Table 1.2.10 are valid for a trailer weight of 1000 pounds.
-------
-15-
2.D.7 NOx Humidity Correction Factor
The NOx emission factors are normalized to 75 grains of water per pound
of dry air. In order to adjust NOx emissions to different humidity
conditions, a multiplicative correction factor is available. The formula
for the correction factor is given below, and is applicable for all model
years:
HCF - 1.0 - .0047 * (H - 75)
where:
HCF - The NOx humidity correction factor.
H » Humidity level in grains of water per pound of dry air
(20<-H<-140).

LIGHT DUTY GASOLINE POWERED TRUCKS II
3.A INTRODUCTION
This chapter presents the emission factors for light duty gasoline
powered trucks with a gross vehicle weight (GVW) rating between 6,001 and
8,500 pounds (LDGT2). A LDGT2 is defined to be any gasoline fueled motor
vehicle designed primarily for transportation of property and rated
between 6,001 pounds and 8,500 pounds GVW, inclusive. This vehicle type
is required since these trucks were classified as heavy duty vehicles
through the 1978 model year. Beginning with the 1979 model year, these
trucks have been considered as light duty trucks.
In general, every LDGV section and subsection discussion in Chapter 1 is
valid for this chapter. Therefore, these discussions will not be
reiterated. Please refer to Chapter 1 for a complete discussion of the
sections and subsections of this chapter.
As with the other chapters, the emission factors are separated into three
major sections: (1) Emissions, (2) travel weighting fractions, and (3)
emission correction factors.
3.A.I Test Procedure
The test procedure used for determining the LDGT2 basic exhaust emissions
is almost identical to the LDGV test procedure. The difference between
the two test procedures is primarily the road-load horsepower setting.
The LDGV test procedure summarized in Chapter 1 is valid for the LDGT2s.
3.A.2 General Emissions Calculation Equations
Chapter 1 also presents the generalized calculating equations that are
valid for the LDGT2s. Although the emissions, travel weighting
fractions, and emission correction factors for the LDGT2s are different
from the LDGVs, all of the equations are identical.
3'.B EMISSIONS
This section presents the LDGT2 emissions: Basic exhaust emission rates,
crankcase and evaporative HC emission levels, January 1 basic exhaust
emission levels, and idle exhaust emission rates. The pre-1979 model
year LDGT2 were considered heavy duty vehicles; their emission standards
are given in Section A.1.3 of Appendix A. The 1979 and later LDGT2
emission standards are given in Section A.1.2 of Appendix A. The
emissions reflect trucks which have received typical in-use maintenance.
Further, the trucks are not involved in an I/M program.
3.B.I Basic Exhaust Emission Rates
The LDGT2 basic exhaust emission rates are given in Table 1.3.LA. This
table presents the LDGT2 zero mile emission levels and emission
deterioration rates for every model year. The emissions are measured in
grams per mile.

3.B.2 Crankcase and Evaporative HC Emission Levels
The LDGT2 crankcase and evaporative HC emission levels are given in Table
1.3.IB. This table presents the emissions for every model year and
emission component: diurnal losses, hot soak losses, and crankcase losses.
3.B.3 January 1 Basic Exhaust Emission Levels
January 1, 1970 through 1993, LDGT2 basic exhaust emission levels are
given in Tables 1.3.2A through 1.3.2C for HC, CO, and NOx, respectively.
The HC basic exhaust emission levels reflect total, rather than non-
methane, HC emissions and exclude crankcase and evaporative HC levels.
3.B.4 Idle Exhaust Emission Rates (Hot Stabilized)
The LDGT2 hot stabilized idle exhaust emission rates are given in Table
1.3.3. These emissions are measured in grams per minute and reflect
engines operating in a hot stabilized condition.
3.C TRAVEL WEIGHTING FRACTIONS
The LDGT2 travel weighting fractions are the individual model year
proportions of the total LDGT2 VMT. To generate the travel weighting
fractions, three distributions are required: (1) the fleet annual mileage
accumulation rate distribution, (2) the registration distribution, and
(3) the estimated fleet sales fraction distribution (to account for the
proportional increase of diesel powered trucks). The first and second
distributions are given in Table 1.3.4A, and the third distribution is
given in Table 1.3.4B. More detailed information is available in Chapter
1 on these three distributions.
The travel weighting fractions in this document reflect a January 1
evaluation date. For the LDGT2s, the model year is assumed to begin
sales on the October 1 preceding the corresponding calendar year.
Further, it is assumed that the trucks are sold and accumulate mileage
according to a uniform distribution. These assumptions permit the
estimation of the January 1 fleet mileage accumulation rate distribution
and the January 1 registration distribution from July 1 information. An
example of the travel weighting fraction calculation is given in
Table 1.3.5.
3.D EMISSION CORRECTION FACTORS
The LDGT2 basic exhaust emission levels are based on test results under
the standardized conditions defined in Chapter 1. However, the basic
exhaust emission levels are affected by ambient and truck usage
conditions which differ from the prescribed test procedure. The
conditions under which emissions are known to vary are the average speed,
ambient temperature, fraction of VMT in cold and hot start operating
modes, use of air conditioning, carrying of an extra load, trailer
towing, and humidity level. Emission correction factors are available to
compensate for these conditions.
-------
-18-
The LDGT2 emission correction factors are based on the LDGV information.
Therefore, the LDGT2 correction factors are those from the LDGVs, and the
discussions in Chapter 1 are valid for the LDGT2s.
3.D.I Speed Correction Factor
The test procedure used for collecting the basic exhaust emissions is a
driving cycle with an average speed of 19.6 mph. For those situations
where the average speed of the truck deviates from this value, a speed
correction factor is applied. The LDGT2 average cycle speed emission
correcion factor is given in Table 1.3.6.
3.D.2 Emission Temperature Correction Factor
The established LDGT2 emissions test procedure requires an ambient
temperature between 68 °F and 86°F. For those situations where the
ambient temperature is not in this range, an emission temperature
correction factor is applied. Table 1.3.7A presents this correction
factor for the LDGT2s.
3.D.3 Speed/Temperature/Operating-Mode Emission Correction Factor
A single emission correction factor called Ripstwxn adjusts for speed,
temperature, and operating-mode conditions that differ from the basic
test procedure. As described in Chapter 1, Ripstwxn depends on
normalized bag fractions. The LDGT2 normalized bag fractions are given
in Table 1.3.7B.
3.D.4 Air Conditioning Correction Factor
The LDGT2 emissions can be significantly affected by the use of air
conditioning. These correction factors are given in Table 1.3.8A. The
fractions of LDGT2s equipped with an air conditioner, by model year, are
given in Table 1.3.8A.
3.D.5 Extra Load Correction Factor
The basic exhaust emission rates are based on the "typical" truck weight
with a driver and passenger, fuel, and other liquids. There are,
however, situations in which trucks have extra weight due to additional
passengers, luggage, load, etc. In these events, emissions are known to
change.
To apply the truck extra load correction factor found in Table 1.3.9 to a
specific situation, it is necessary for a user to have an estimate of the
percentage of LDGT2 VMT accumulated with an additional 500 pounds.
3.D.6 Trailer Towing Correction Factor
As with the extra load correction factor, the trailer towing correction
factor will adjust LDGT2 emissions for usage conditions which differ from
the basic test procedure. The correction factor coefficients given in
Table 1.3.10 are valid for a trailer weight of 1000 pounds.

3.D.7 NO* Humidity Correction Factor
The NOx emission factors are normalized to 75 grains of water per pound
of dry air. la order to adjust NOx emissions to different humidity
conditions, a multiplicative correction factor is available. The formula
for the correction factor is given below, and is applicable for all model
years:
HCF - 1.0 - .0047 * (H - 75)

HEAVY DUTY GASOLINE POWERED VEHICLES
4.A INTRODUCTION
This chapter presents the emission factors for the heavy duty gasoline
powered vehicles (HDGV). A HDGV is defined to be any gasoline fueled
motor vehicle designated primarily for the transportation of property and
rated at more than 8,500 pounds gross vehicle weight (GVW), or designated
primarily for transportation of persons and having a capacity of more
than 12 persons.
This chapter presents the HDGV emission factors in three major sections:
(1) Emissions, (2) travel weighting fractions, and (3) emission
correction factors.
4.A.I Test Procedure
The method for determining the HDGV emission levels is based on a test
procedure that is different from the procedures used in earlier editions
of AP-A2. The HDGV basic exhaust emission rates are based on the engine
dynamometer transient test procedure stipulated in the Federal Register
(45 FR 4181, January 21, 1980) and the Code of Federal Regulations (40
CRF, Part 86, Subpart N, July 1, 1980). The basic test conditions under
which the HDGVs are tested are as follows:
1. Anbient temperature range is 688F through 86°F.
2. Absolute humidity is adjusted to 75 grains of water per pound of
dry air.
3. Estimated cycle speed is 19.9 mph with 27% idle operation.
4. Average percent VMT in a cold start operation is 14.3%.
5. Average percent VMT in a hot start operation is 86.7%.
6. No average percent VMT in the stabilized operation.
7. Estimated trip length is 6.5 miles.
The test procedure for the HDGVs can be briefly described by the
following:
1. Generate the maximum torque vs. speed curve of the engine.
2. Precondition the engine with practice cycle runs.
3. With the engine off, let it sit for at least 12 hours between
68°F and 86°F. An optional procedure is the forced cool-down
procedure, whereby cool water is circulated (and/or air directed
onto the engine) through the engine's water coolant system until
the engine oil is between 68°F and 75°F.
4. Conduct the cold start test. The estimated mileage is 6.5 miles
and cycle speed is 19.9 mph.
5. Turn off the engine.
6. Keep the engine off for 20 minutes.
7. Conduct the hot start test. The cycle is the same as the cold
start cycle.
8. Calculate the grams of-pollutant and total brake horsepower-hour
for each test cycle.
-------
-21-
9. Correct NOx to 75 grains of water per pound of dry air.
10. Calculate the basic exhaust emissions in grams per brake
horsepower-hour.
4.A.2 General Emissions Calculation Equations
To calculate the HDGV emissions, the following generalized equations are
used:
(a) BEFnpst - SUMi(BERipn * [NMi] * TFin * SCFips * TCFipt + CCEVi *
TFin)
(b) lEFnp - SUMi(IERipn * [NMi] * TFin)

levels, and (4) idle exhaust emission rates. The emission standards are
given in Section A.1.3 of Appendix A. The emissions reflect vehicles
which have received typical in-use maintenance. Further, the vehicles
are not involved in an I/M program.
The discussions in Chapter 1 for the four emission subsections are valid
for the HDGVs. Therefore, the discussions will not be reiterated.
Please refer to Chapter 1 for a complete discussion at the following four
subsections.
A.B.I Basic Exhaust Emission Rates
The HDGV basic exhaust emission rates are given in Table 1.4.1A. This
table presents the HDGV zero mile emission levels and emission
deterioration rates for every model year. From the HDGV test procedure,
emissions are measured in grams per brake horsepower-hour. However, the
emissions in this section are given in grams per mile to be consistent
with other emission measurements.
4.B.2 Crankcase and Evaporative HC Emission Levels
The HDGV crankcase and evaporative HC emission levels are given in Table
1.4.IB. This table presents the emissions for every model year and
emission component: diurnal losses, hot soak losses, and crankcase losses.
4.B.3 January 1 Basic Exhaust Emission Levels
The January 1, 1970 through 1993, HDGV basic exhaust emission levels are
given in Tables 1.4.2A through 1.4.2C for HC, CO, and NOx, respectively.
The HC basic exhaust emission levels reflect total, rather than non-
methane, HC emissions and exclude crankcase and evaporative HC emission
levels.
4.B.4 Idle Exhaust Emission Rates (Hot Stabilized)
The HDGV hot stabilized idle exhaust emission rates are given in Table
1.4.3. These emissions are measured in grams per minute and reflect
engines operating in a hot stabilized condition.
4.C TRAVEL WEIGHTING FRACTIONS
The HDGV travel weighting fractions are the individual model year
proportions of the total HDGV VKT. To generate the HDGV travel weighting
fractions, two distributions are required: (1) the fleet annual mileage
accumulation rate distribution and (2) the registration distribution.
These two distributions are given in Table 1.4.4. More detailed
information is available in Chapter 1 on these distributions.
The travel weighting fractions in this document reflect a January 1
evaluation date. For the HDGVs, the model years are assumed to begin
sales on January 1. Further, it is assumed that the vehicles are sold
and accumulate mileage according to a uniform distribution. These
assumptions permit the estimation of the January 1 fleet mileage
accumulation rate distribution and the January 1 registration

distrlbution from July 1 information. The travel weighting fractions are
given in Table 1.1.5.
4.D EMISSION CORSECTION FACTORS
The HDGV basic exhaust emission levels are based on test results under
the standardized conditions defined in Section 4.A.I. However, the basic
exhaust .emission levels are affected by ambient and vehicle usage
conditions which differ from the prescribed test procedure. The
conditions under which HDGV emissions are known to vary are the average
speed and ambient- temperature. Emission correction factors are available
to compensate for these conditions.
4.D.I Speed Correction Factor
The test procedure used for collecting the basic exhaust emissions is a
transient engine cycle with an estimated speed of about 20.0 mph. For
those situations where the average speed of the vehicle deviates from
this value, a speed correction factor is applied. The HDGV speed
correction factor equations are as follows:
(a) SCFips - EXP(Aip + Bip*s + Cip*s2) for HC and CO, and
(b) SCFips - Aip + Bip*s for NOx
where
SCFips - The correction factor for model year i and pollutant p at
the average speed of s.
EXP - The exponential function.
Aip « The speed correction factor intercept coefficient for
model year i and pollutant p.
Bip = The speed correction factor first order coefficient for
model year i and pollutant p.
Cip - The speed correction factor second order coefficient for
model year i and pollutant p.
The coefficients for the speed correction factor equations are given in
Table 1.4.6. The speed correction factors are only valid for speeds in
the 5 through 55 mph range.
4.D.2 Emission Temperature Correction Factor
The established HDGV test procedure requires an ambient temperature
between 68°F and 86°F. For situations where the ambient temperature is
not in this range, an emission temperature correction factor is applied.
This temperature correction factor differs slightly in form from the
temperature correction factor given in Chapter 1. The HDGV temperature
correction factor is for the entire transient test as opposed to the LDGV
temperature correction factors for the individual test segments. The
-------

HDGV temperature correction factor is given in Table 1.4.7 and the
equation is as follows:
TCFipt - EXP(TCiptt(T - TT))
where the lower case letters are subscripts and
TCFipt = The emission temperature correction factor for model year
i, pollutant p, and ambient temperature t.
EXP ** The exponential function.
TCiptt » The temperature correction factor coefficient for model
year 1, pollutant p, and reference temperature tt.
T - Ambient temperature (Fahrenheit).
TT - Reference temperature which equals 67.5°F when T is less
than 680F and equals 86.5°F when T is greater than 86°F.

LIGHT DUTY DIESEL POWERED VEHICLES
5. A INTRODUCTION
Diesel powered passenger cars are becoming more prominent in the light
duty vehicle fleet* As a result, emission factors are required for these
light duty diesel powered vehicles (LDDV). A LDDV is defined to be any
diesel fueled motor vehicle designated primarily for transportation of
persons and having a capacity of 12 persons or fewer.
As with the other chapters, the LDDV emission factors are presented in
three major sections: (1) Emissions, (2) travel weighting fractions, and
(3) emission correction factors.
5.A.I Test Procedure
The test procedure used for determining the LDDV basic exhaust emissions
is identical to the LDGV test procedure. Therefore, refer to Chapter 1
for a brief overview.
5.A.2 General Emissions Calculation Equations
The LDDV generalized equations are almost identical to the LDGV
equations. The differences are the four optional emission correction
factors and the crankcase and evaporative HC emissions. To calculate the
LDDV emissions, the following generalized equations are used:
(a) BEFnpstwx - SUMi(BERipn * [NMi] * TFin * Ripstwxn)
(b) lEFnp = SUMi(IERipn * [NMi] * TFin)
where the lower case letters are subscripts, the [ ]'s refer to optional
variables and:
BEFnpstwx - The basic exhaust emission factors in grams/mile on
January 1 of calendar year n, pollutant p, average speed
s, ambient temperature t, VMT fraction of vehicles in a
cold start mode w, and VMT fraction of vehicles in a hot
start mode x.
SUMi( ) - The summation over 20 model years from i=n-19 to i=n,
where n is the calendar year.
BERipn «> The basic exhaust emission level in grams/mile for model
year 1 and pollutant p on January 1 of calendar year n.
NMI » The non-methane fraction of total HC for model year i.
This optional variable can only be applied to HC
emissions and is defined in Section E of the INTRODUCTION.
TFin « The model year i fraction of the total LDDV miles driven
on January 1 of calendar year n.
-------

Ripstwxn = The speed/temperature/operating-mode correction factor
for model year i, pollutant p, average speed s, ambient
temperature t, VMT fraction in a cold start w, and VHT
fraction of vehicles in a hot start x; on January 1 of
calendar year n.
lEFnp = The idle exhaust emission factors in grams/minute on
January 1 of calendar year n for pollutant p.
XERipn ° The idle exhaust emission levels in grams/minute for
model year i and pollutant p on January 1 of calendar
year n.
5.B EMISSIONS
This section discusses the LDDV emission estimates: Basic exhaust
emission rates, crankcase and evaporative HC emission levels, January 1
basic exhaust emission levels, and idle exhaust emission rates. The
emission standards are given in Section A.1.1 of Appendix A. The
emissions reflect vehicles which have received typical in-use
maintenance. Further, the vehicles are not involved in an I/M program.
With the exception of the crankcase and evaporative HC emissions, the
discussions of the different emissions in Chapter 1 are also valid for
the LODVs. Therefore, the discussions will not be reiterated. Please
refer to Chapter 1 for the discussions that correspond to the subsections
below.
5.B.I Basic Exhaust Emission Rates
The LDDV basic exhaust emission rates are given in Table 1.5.1. This
table presents the LDDV zero mile emission levels and emission
deterioration rates for every model year. The emissions are measured in
grams per mile.
5.B.2 Crankcase and Evaporative HC Emission Levels
LDDVs are considered to have insignificant crankcase and evaporative HC
emission levels. Therefore, no emission estimates are given.
5.B.3 January 1 Basic Exhaust Emission Levels
January 1, 1970 through 1993, LDDV basic exhaust emission levels are
given in Tables 1.5.2A through 1.5.2C for HC, CO, and NOx, respectively.
The HC basic exhaust emission levels reflect total, rather than non-
methane, HC emissions.
5.B.4 Idle Exhaust Emission Rates (Hot Stabilized)
The LDDV hot stabilized idle exhaust emission rates are given in Table
1.5.3. These emission levels are measured in grams per minute and
reflect engines operating in a hot stabilized condition.
-------
-27-
5.C TRAVEL WEIGHTING FRACTIONS
The LDDV travel weighting fractions are individual model year proportions
of the total LDDV VMT. To generate the travel weighting fractions, three
distributions are required: '(1) the fleet annual mileage accumulation
rate distribution, (2) the registration distribution, and (3) the
estimated fleet sales fraction distribution (to account for the
proportional increase of diesel powered vehicles). The first and second
distributions are given in Table 1.5.4A, and the third distribution is
given in Table 1.5.4B. More detailed information is available in Chapter
1 on these distributions.
The travel weighting fraction in this document reflect a January 1
evaluation date. For the LDDVs, the model year is assumed to begin sales
on the October 1 preceding the corresponding calendar year. Further, it
is assumed that the vehicles are sold and accumulate mileage according to
a uniform distribution. These assumptions permit the estimation of the
January 1 fleet mileage accumulation rate distribution and the January 1
registration distribution from July 1 information. An example of the
travel weighting fraction calculation is given in Table 1.5.5.
5.D EMISSION CORRECTION FACTORS
The LDDV basic exhaust emission levels are based on test results under
the standardized conditions defined in Chapter 1. However, the basic
exhaust emission levels are affected by ambient and vehicle usage
conditions which differ from the prescribed test procedure. The
conditions under which LDDV emissions are known to vary are the average
speed, ambient temperature, and fraction of VMT in cold and hot start
operating modes. Emission correction factors are available to compensate
for these conditions. Use of air conditioning, carrying of an extra
load, trailer towing, and humidity levels may affect LDDV emissions, but
no information is available to estimate the effects.
5.D.I Speed Correction Factor
The test procedure used for collecting the basic exhaust emissions is a
driving cycle with an average speed of 19.6 mph. For those situations
where the average speed of the vehicle deviates from this value, a speed
correction factor is applied. This correction factor will now be
examined and later incorporated into the Rlpstwxn correction factor in
Section 5.D.3.
The LDDV speed correction factor is based on the heavy duty diesel
vehicle (HDDV) correction factor, and is fully defined in Section 7.D.I
of Chapter 7. The speed correction factor for LDDVs is normalized to
19.6. mph. The LDDV speed correction factor equation is as follows:
SCFipswx - EXP(Aip + Bip*s + Cip*s2)/EXP(Aip + Bip*sadj + Cip*sadj2)
where the lower case letters are subscripts and
SCFipswx » The speed correction factor for model year i, pollutant
p, and average speed s, normalized for the cold start w
and hot start x VMT fractions.
-------
-28-
EXP = The exponential function.
Aip = The speed correction factor intercept coefficient for
model year i and pollutant, p.
Bip = The speed correction factor first order coefficient for
model year i and pollutant p*
Cip = The speed correction factor second order coefficient for
model year i and pollutant p.
sadj = The adjusted speed, adjusted for the cold start w and hot
start x VMT fractions. I/ sadj = ((w + x)/26) + «1 - w -
The user is cautioned that the correction factor as given in Table 1.5.6
is only valid for speeds in the 5 through 55 mph range since the
regression equations were based on speed data in that range.
Extrapolations to speeds beyond this range should not be made.
5.D.2 Emission Temperature Correction Factor
The established LODV emissions test procedure requires an ambient
temperature between 68°F and 86°F. For those situations where the
ambient temperature is not in this range, an emission temperature
correction factor is applied. Table 1.5.7A presents this correction
factor for the LDDVs. Based upon the coefficients given in Table 1.5.7A
(which are all zero), LDDV emissions will not be affected by
temperature. Based on engineering judgement and limited data, LODV
emissions appear to be insensitive to temperature.
5.D.3 Speed/Temperature/Operating-Mode Emission Correction Factor
A single emission correction factor called Ripstwxn adjusts for speed,
temperature, and operating-mode conditions that differ from the basic
test procedure. As described in Chapter 1, Ripstwxn depends on
normalized bag fractions. The LDDV normalized bag fractions are given in
Table 1.5.7B.

Chapter 6
LIGHT DUTY DIESEL POWERED TRUCKS
6.A INTRODUCTION
The light duty diesel powered trucks (LDDT) are becoming more prominent
in the light duty truck fleet. Therefore, the LDDT emission factors are
required. A LDDT is defined to be any diesel fueled motor vehicle
designed primarily for transportation of property and rated at 8,500
pounds tro«« vehicle weight or less.
This chapter, like all others, divides the emission factors into three
major sections: (1) Emissions, (2) travel weighting fractions, and (3)
emission correction factors.
6.A.I Test Procedure
The test procedure used for determining the LDDT basic exhaust emissions
is almost identical to the LDGV test procedure. The difference between
the two test procedures is primarily the road-load horsepower setting.
The summary of the test procedure in Chapter 1 is correct for LDDTs.
Therefore, refer to Chapter 1 for a brief overview.
6.A.2 General Emissions Calculation Equations
The generalized calculating equations for the LDDTS are presented in
Chapter 5.. All of the equations are identical, although the emissions,
travel weighting fractions, and emission correction factors levels for
LDDTs are different from the LDDVs.
6.B EMISSIONS
This section discusses the LDDT emission estimates: Basic exhaust
emission rates, crankcase and evaporative HC emission levels, January 1
basic exhaust emission levels, and idle exhaust emission rates. The
emission standards are given in Section A.1.2 of Appendix A. Prior to
the 1978 model year, the number of LDDTs are considered insignificant.
As a result, no emissions are measured prior to January 1, 1978. The
emissions also reflect trucks which have received typical in-use
maintenance. Further, the trucks are not involved in an I/M program.
With the «xc«ption of the crankcase and evaporative HC emissions, the
discussions of the different emissions in Chapter 1 are valid for the
LDDTs. Therefore, the discussions of the different emissions in Chapter
1 will not be reiterated. Please refer to Chapter 1 for the discussions
that correspond to the subsections below.
6.B.1 Basic Exhaust Emission Rates
Th* LDDT basic exhaust emission rates are given in Table 1.6.1. This
table presents the LDDT zero mile emission levels and emission
deterioration rates for every model year. The emissions are measured in
grams per mile.
-------
-30-
6.B.2 Crankcase and Evaporative HC Emission Levels
LDDT are considered to have insignificant crankcase and evaporative HC
emission levels. Therefore, no emission estimates are given.
6.B.3 January 1 Basic Exhaust Emission Levels
January 1, 1978 through 1993, LDDT basic exhaust emission levels are
given in Tables 1.6.2A through 1.6.2C for HC, CO, and NOx, respectively.
The HC basic exhaust emission levels reflect total, rather than
non-methane, HC emissions.
6.B.4 Idle Exhaust Emission Rates (Hot Stabilized)
The LDDT hot stabilized idle exhaust emission rates are given in Table
1.6.3. These emission levels are measured in grams per minute and
reflect engines operating in a hot stabilized condition.
6.C TRAVEL WEIGHTING FRACTIONS
The LDDT travel weighting fractions are the individual model year
proportion of the total LDDT VMT. To generate the" travel weighting
fractions, three distributions are required: (1) the fleet annual mileage
accumulation rate distribution, (2) the registration distribution, and
(3) the estimated fleet sales fraction distribution (to account for the
proportional increase of diesel powered trucks). The first and second
distributions are given in Table 1.6.4A, and the third distribution is
given in Table 1.6.4B. More detailed information is available in Chapter
1 on these distributions.
The travel weighting fractions in this document reflect a January 1
evaluation date. For the LDDTs, the model year is assumed to begin sales
on the October 1 preceding the corresponding calendar year. Further, it
is assumed that the trucks are sold and accumulate mileage according to a
uniform distribution. These assumptions permit the estimation of the
January 1 fleet mileage accumulation rate distribution and the January 1
registration distribution from July 1 information. An example of the
travel weighting fraction calculation is given in Table 1.6.5.
6.D EMISSION CORRECTION FACTORS
The LDDT basic exhaust emission levels are based on test results under
the standardized conditions defined in Chapter 1. However, the basic
exhaust emission levels are affected by ambient and truck usage
conditions which differ from the prescribed test procedure. The
conditions under which LDDT emissions are known to vary are the average
speed, ambient temperature, and fraction of VMT in cold and hot start
operating modes. Emission correction factors are available to compensate
for these conditions. Use of air conditioning, carrying of an extra
load, trailer towing, and humidity levels may affect LDDT emissions, but
no information is available to estimate the effects.
-------
-31-
6.D.I Speed Correction Factor
The test procedure used for collecting the basic exhaust emissions is a
driving cycle with an average speed of 19.6 mph. For those situations
where the average speed of the truck deviates from this value, a speed
correction factor is applied. This correction factor will now be
examined and later incorporated into the Ripstwxn correction factor in
Section 6.D.3.
The LDDT emission cycle speed correction factor given in Table 1.6.6 is
based on the heavy duty diesel vehicle (KDDV) correction factor and Is
fully defined in Section 7.D.I of Chapter 7. The LDDT speed correction
factor is normalized to 19.6 and is identical to the LDDV speed
correction factor.
The user is cautioned that this correction factor is only valid for
speeds in the 5 through 55 mph range since the regression equations were
based on speed data in that range. Extrapolations to speeds beyond this
range should not be made.
6.D.2 Emission Temperature Correction Factor
The established LDDT emissions test procedure requires an ambient
temperature between 68°F and 86°F. For those situations where the
ambient temperature is not in this range, an emission temperature
correction factor is applied. Table 1.6.7A presents this correction
factor for the LDDTs. Based on the coefficients given in Table 1.6.7A
(which are all zero), LDDT emissions will not be affected by
temperature. Based on engineering judgement and limited data, diesel
emissions appear to be insensitive to temperature.
6.D.3 Speed/Temperature/Operating-Mode Emission Correction Factor
A single emission correction factor called Ripstwxn adjusts for speed,
temperature, and operating-mode conditions that differ from the basic
test procedure. As described in Chapter 1, Ripstwxn . depends on
normalized bag fractions. The LDDT normalized bag fractions are given in
Table 1.6.7B.

Chapter 7
HEAVY DUTY DIESEL POWERED VEHICLES
7.A INTRODUCTION
This chapter presents the emission factors for the heavy duty diesel
powered vehicles (HDDV). A HDDV is defined to be any diesel fueled motor
vehicle designated primarily for the transportation of property and rated
at more than 8,500 pounds of gross vehicle weight (GVW), or designated
primarily for transportation of persons and having a capacity of more
than 12 persons.
This chapter presents the HDDV emission factors in three major sections:
(1) Emissions, (2) travel weighting fractions, and (3) emission
correction factors.
7.A.I Test Procedure
The test procedure used for determining the HDDV basic exhaust emissions
is almost identical to the HDGV test procedure. The major difference
between the two test procedures is the test cycle. The HDDV test
procedure is similar to the one for HDGVs. Therefore, refer to Chapter 4
for a brief overview. The specific differences are as follows:
1. The HDDV test procedure estimated cycle speed is 19.2 mph with
37% idle operation.
2. The HDDV test procedure has the estimated trip length of 6.4
miles.
3. NOx is not corrected for humidity.
7.A.2 General Emissions Calculation Equations
To calculate the HDDV emissions, the following generalized equations are
used:
(a) BEFnpst = SUMi(BERipn * [NMi] * TFin "* SCFips * TCFipt)
(b) lEFnp = SUMi(IERipn * [NMi] * TFin)
where the lower case letters are subscripts, the [ ]'s refer to optional
variables and:
BEFnpst « The basic exhaust emission factors in grams per mile on
January 1 of calendar year n for pollutant p, average
speed s, and ambient temperature t.
SUMi( ) = The summation over 20 model years from i=n-19 to i=n,
where n is the calendar year.
BERipn - The basic exhaust emission level in grams/mile for model
year i and pollutant p on January 1 of calendar year n.
-------
-33-
NMi The non-methane fraction of total HC for model year i.
This optional variable can only be applied to HC
emissions and is defined in Section E of the INTRODUCTION.
TFin - The model year i fraction of the total HDDV miles driven
on January 1 of calendar year n.
SCFips - The speed correction factor for model year i and
pollutant p at the average speed of s.
TCFipt - The temperature correction factor for model year i and
pollutant p at the ambient temperature of t.
lEFnp » The idle exhaust emission factors in grams/minute on
January 1 of calendar year n for pollutant p.
lERlpn » The idle exhaust emission level in grams/minute for model
year i and pollutant p on January 1 of calendar year n.
7.B EMISSIONS
This section discusses the emission estimates for the HDDVs. The four
subsections are (1) basic exhaust emission rates, (2) crankcase and
evaporative HC emission levels, (3) January 1 basic exhaust emission
levels, and (4) idle exhaust emission rates. The emission standards are
given in Section A.1.4 of Appendix A. The emissions reflect vehicles
which have received typical in-use maintenance. Further, the vehicles
are not involved in an I/M program.
With the exception of the crankcase and evaporative HC emissions, the
discussions in Chapter 1 for the four emission subsections are valid for
the HDDVs. Therefore, the discussions will not be reiterated here.
Please refer to Chapter 1 for the discussions that correspond to the
subsections below.
7.B.I Basic Exhaust Emission Rates
The HDDV basic exhaust emission rates are given in Table 1.7.1A. This
table presents the HDDV zero mile emission levels and emission
deterioration rates for every model year. From the HDDV test procedure,
emissions are measured in grams per brake horsepower-hour. However, the
emissions in this section are given in grams per mile for consistency.
7.B.2 Crankcase and Evaporative HC Emission Levels
HDDVs are considered to have insignificant crankcase and evaporative HC
emission levels. Therefore, no emission estimates are given.
7.B.3 January 1 Basic Exhaust Emission Levels
The January 1, 1970 through 1993, HDDV basic exhaust emission levels are
given in Tables 1.7.2A through 1.7.2C for HC, CO, and NOx, respectively.
The HC basic exhaust emission levels reflect total, rather than
non-methane, HC emissions.
-------
-34-
7.B.4 Idle Exhaust Emission Rates (Hot Stabilized)
The HDDV hot stabilized idle exhaust emission rates are given in Table
1.7.3. These emissions are measured in grams per minute and reflect
engines operating in a hot stabilized condition.
7.C TRAVEL WEIGHTING FRACTIONS
The HDDV travel weighting fractions are the individual model year
proportions of the total HDDV VMT. To generate the HDDV travel weighting
fractions, two distributions are required: (1) the fleet annual mileage
accumulation rate distribution and (2) the registration distribution.
These two distributions are given in Table 1.7.4. More detailed
information is available in Chapter 1 on these distributions.
The travel weighting fractions in this document reflect a January 1
evaluation date. For the HDDVs, the model years are assumed to begin
sales on January 1. Further, it is assumed that the vehicles are sold
and accumulate mileage according to a uniform distribution. These
assumptions permit the estimation of the January 1 fleet mileage
accumulation rate distribution and the January 1 registration
distribution from July 1 information. The travel weighting fraction are
given in Table 1.7.5.
7.D EMISSION CORRECTION FACTORS
The HDDV basic exhaust emission levels are based on test results under
the standardized conditions defined in Section 4.A.I of Chapter 4 and
Section 7.A.I. However, the basic exhaust emission levels are affected
by ambient and vehicle usage conditions which differ from the prescribed
test procedure. The conditions under which HDDV emissions are known to
vary are the average speed and ambient temperature. Emission correction
factors are available to compensate for these conditions.
7.D.I Speed Correction Factor
The test procedure used for collecting the basic exhaust emissions is a
transient engine cycle with an estimated speed of about 20.0 mph. For
those situations where the average speed of the vehicle deviates from
this value, a speed correction factor Is applied. The HDDV speed
correction factor equation is as follows:
SCFips = EXP(Aip + Bip*s + Cip*s2)
where
SCFips = The correction factor for model year 1 and pollutant p at
the average speed of s.
EXP = The exponential function.
Alp = The speed correction factor intercept coefficient for
model year i and pollutant p.
-------
-35-
Bip - The speed correction factor first order coefficient for
model year 1 and pollutant p.
Cip » The speed correction factor second order coefficient for
model year i and pollutant p.
The coefficients for the speed correction factor equations are given in
Table 1.7.6. The speed correction factors are only valid for speeds in
the 5 through 55 mph range. Further, the speed correction factors are
normalized to 20.0 mph.
7.D.2 Emission Temperature Correction Factor
The established HDDV emissions test procedure requires an ambient test
temperature between 68°F and 86°F. For situations which differ from this
ambient temperature range, an emission temperature correction factor is
applied. This temperature correction factor differs slightly from the
temperature correction factor given in Chapter 1. The HDDV temperature
correction factor is for the entire transient test as opposed to the LDGV
temperature correction factors for the individual test segments. The
HDDV temperature correction factor is given in Table 1.7.7 and the
equation is as follows:
TCFipt - EXP(TCiptt(T - TT))
where the lower case letters are subscripts and
TCFipt The emission temperature correction factor for model year
i, pollutant p, and ambient temperature t.
EXP - The exponential function.
TCiptt - The temperature correction factor coefficient for model
year i, pollutant p, and reference temperature tt.
T <> Ambient temperature (Fahrenheit).
TT » Reference temperature which equals 67.5°F when T is less
than 68°F and equals 86.5°F when T is greater than 86°F.
All of the coefficients in Table 1.7.7 are zero. This indicates that the
HDDV emissions are not affected by temperature.

Chapter 8
MOTORCYCLES
8.A INTRODUCTION
Motorcycles usually are not considered a significant source of air
pollution. However, they are becoming a dominant fleet. In 1978,
approximately 7.3 million motorcycles (MC) were registered in the United
States. With the exception of light duty gasoline powered vehicles and
trucks (less than 6,001 pounds gross vehicle weight), motorcycles are
more abundant than other vehicle types.
A motorcycle is defined as any motor vehicle designed to travel with not
more than three wheels in contact with the ground, and weighting less
than 1,500 pounds.
The MC fleet is composed of six engine size-type combinations: small,
medium, and large engine sizes, each size having two-stroke and
four-stroke engine types. Small or Class I motorcycles have engine
displacements in the 50 cubic centimeter (cc) through 169 cc range..
Medium or Class II motorcycles have engine displacements in the 170 cc
through 279 cc range. Large or Class III motorcycles have engine
displacements in the 280 cc and over range.
As with other chapters, the MC emission factors are divided into three
sections: Emissions, travel weighting fractions, and emission correction
factors.
8.A.I Test Procedure
With the exception of the Class I motorcycles, the MC basic exhaust
emissions test procedure is identical to the LDGV test procedure.
Therefore, with the one class exception, the summary of the test
procedure in Chapter 1 is correct for the MCs. Given below is a list of
Class I motorcycle test procedure summary statistics that differ from the
LDGV test procedure.
1. Average speed is 17.8 mph.
2. Average percent VMT in cold start operation is 18.3%.
3. Average percent VMT in hoc start operation is 24.2%.
4. Average percent VMT in the stabilized operation is 57.5%.
5. Average trip length is 6.8 miles.
6. Test segment #1 (cold start) and #3 (cold start) each have an
average trip length of 2.89 miles and speed of 20.6 mph.
7. Tc^t segment //2 (stabilized) has the average trip length of 3.91
miles and speed of 16.2 mph.
8.A.2 General Emissions Calculation Equations
The MC generalized equations are almost identical to the LDGV equations.
The differences are three optional emission correction factors that are
not applicable for MCs: air conditioning, extra load, and trailer
towing. With these three exceptions, the MC emission factors calculating
equations are identical to the LDGV equations given in Chapter 1.
-------
-37-
8.B EMISSIONS
This section discusses the MC emission estimates: Basic exhaust emission
rates, crankcase and evaporative HC emission levels, January 1 basic
exhaust emission levels, and idle exhaust emission rates. The emission
standards are given in Section A.1.5 of Appendix A. The emissions
reflect motorcycles which have received typical in-use maintenance.
Further, the motorcycles are not involved in an I/M program.
With the exception of the six engine size-type combinations being sales
weighted, the discussions of the different emissions in Chapter 1 are
also valid for the MCs. Therefore, the discussions will not be
reiterated. Please refer to Chapter 1 for the discussions that
correspond to the subsections below. Further, it is assumed that the MC
emissions reflect exactly the standard.zed test conditions described in
Chapter 1.
8.B.I Basic Exhaust Emission Rates
The MC basic exhaust emission rates are given in Table 1.8.1A. This
table presents the MC zero mile emission levels and emission
deterioration rates for every model year. The emissions are measured in
grans per mile.
8.B.2 Crankcase and Evaporative HC Emission Levels
The MC crankcase and evaporative HC emission levels are given in Table
1.8.IB. This table presents the emissions for every model year and
emission component: diurnal losses, hot soak losses, and crankcase losses.
8.B.3 January 1 Basic Exhaust Emission Levels
January 1, 1970 through 1993, MC basic exhaust emisson levels are given
in Table 1.8.2A through 1.8.2C for HC, CO, and NOx, respectively. The HC
basic exhaust emission levels reflect total, rather than non-methane, HC
emissions and exclude crankcase and evaporati've HC levels.
8.B.4 Idle Exhaust Emission Rates (Hot Stabilized)
The MC hot stabilized idle exhaust emission rates are given in Table
1.8.3. These emissions are measured in grams per minute and reflect
engines operating in a hot stabilized condition.
8.C TRAVEL WEIGHTING FRACTIONS
The MC travel weighting fractions are the individual model year
proportions of the total MC VMT. To generate the MC travel weighting
fractions, two distributions are required: (1) the fleet annual mileage
accumulation rate distribution and (2) the registration distribution.
These two distributions are given in Table 1.8.4. More detailed
information is available in Chapter 1 on these distributions.
-------
-38-
The travel weighting fractions in this document reflect a January 1
evaluation date. For the MCs, the model year is assumed to begin sales
on January 1. Further, it is assumed that the motorcycles are sold and
accumulate mileage according to a uniform distribution. These
assumptions permit the estimation of the January 1 fleet mileage
accumulation rate distribution and the January 1 registration
distribution from July 1 information. The travel weighting fractions are
given in Table 1.8.5.
8.D EMISSION CORRECTION FACTORS
The MC basic exhaust emission levels are typically based on test results
under the standardized conditions defined in Chapter 1. However, the
basic exhaust emission levels are affected by ambient and usage
conditions which differ from the prescribed test procedure. The
conditions under which emissions are known to vary are the average speed,
anbient temperature, fraction of VMT in cold and hot start operating
conditions, and humidity level. Emission correction factors are
available to compensate for these varying conditions.
The MC emission correction factors are based on the LDGV information and
the discussions in Chapter 1 are valid for MCs.
8.D.I Speed Correction Factor
The test procedure used for collecting the basic exhaust emissions is
typically a driving cycle with an average speed of 19.6 mph. For those
situations where the average speed of the MC deviates from this, value, a
speed correction factor is applied. The MC speed emission correction
factor is given in Table 1.8.6.
8.D.2 Emission Temperature Correction Factor
The established motorcycle emissions test procedure requires an ambient
test temperature between 68°F and 86°F. For those situations where the
ambient temperature is not in this range, an emission .temperature
correction factor is applied. Table 1.8.7A presents this correction
factor for the MCs.
8.D.3 Speed/Temperature/Operating-Mode Emission Correction Factor
A single emission correction factor called Ripstwxn adjusts for speed,
temperature, and operating-mode conditions that differ from the basic
test procedure. As described in Chapter 1, Ripstwxn depends on
normalized bag fractions. The MC normalized bag fractions are given in
Table 1.8.7B.
8.D.A NOx Humidity Correction Factor
The NOx emission factors are normalized to 75 grains of water per pound
of dry air. In order to adjust NOx emissions to different humidity
conditions, a multiplicative correction factor is available. The foraula
for the correction factor is given below, and is applicable for all model
years:
-------
-39-
HCF - 1.0 - .0047 * (H - 75)
where:
HCF - The NOx humidity corrector factor.
H " Humidity level in grains of water per pound of dry air

PART TWO CALIFORNIA
Chapter 9
CALIFORNIA HIGHWAY MOBILE SOURCE EMISISON FACTORS
Compared to the rest of the nation, California highway mobile sources
usually have different emission control' regulations in effect These
regulations are given in Section A.2 of Appendix A. Although the
emission standards are usually different for these California vehicle
types, the test procedure, emission calculation equations, and emission
factor section and subsection discussions are identical to those given in
low altitude non-California chapters. Therefore, the discussions will
not be repeated. To alter the eight preceding chapters to discuss the
California emission factors, two basic changes are required: (1) Change
the region prefix number in all tables from "1" to "2" and (2) change the
reference Section A.l# to A.2# for Appendix A.
-------
-41-
PART THREE HIGH ALTITUDE NON-CALIFORNIA
Chapter 10
HIGH ALTITUDE NON-CALIFORNIA HIGHWAY
MOBILE SOURCE EMISSION FACTORS
Compared to the low altitude non-California region, the high altitude
non-California highway mobile sources usually have no specific
regulations. Generally, the high altitude vehicle types are the low
altitude counterparts being operated at high altitude. There are a few
exceptions which are given in Section A.I of Appendix A.
The high altitude non-California highway mobile source emission factors
are different from those of the low altitude sources. However, with one
exception, the discussions in Chapters 1 through 8 can be used for the
high altitude emission factors. The one exception is to change the
region prefix number in all tables from "1" to "3". No further
discussions will be made for the high altitude non-California highway
mobile source emission factors.

Appendix A
NEW VEHICLE EMISSION STANDARDS
This appendix presents the emission standards assumed in this document.
At the time of the MOBILE2 release, these were the past, present, and
projected standards. However, it is possible that some of the assumed
standards are now different due to changes in regulations, waivers, etc.
A.I' LOW AND HIGH ALTITUDE NON-CALIFORNIA HIGHWAY VEHICLE EMISSION
STANDARDS
This section presents the emission standards for the eight low and high
altitude non-California vehicle types. The standards are presented in
five subsections. The light duty vehicle and light duty truck fleets are
comprised of both diesel and gasoline powered vehicle types. Further,
the LDGT2 standards are split among the two associated vehicle types.
The pre-1979 model year LDGT2s are heavy duty vehicles while the 1979 and
later model years are light duty trucks. Finally, the high altitude
standards are included in this section since there are few emission
standards specific to the high altitude vehicle types.
All hydrocarbon emission standards in this section are presented for
total hydrocarbon emissions.

LIGHT DUTY VEHICLES
1 Standards do not apply to vehicles with engines less than 50 CID from 1968
through 1974.
2 Different test procedures have been used since the early years of emission
control which vary in stringency. The appearance that the standards were
relaxed from 1971 to 1972 is incorrect. The 1972 standards are actually
more stringent because of the greater stringency of the 1972 test
procedure.
3 Applies only to diesels.
4 Evaporative emissions determined by carbon trap method through 1977, SHED
procedure beginning in 1978. Applies only to gasoline-fueled vehicles.

Appendix B
CALCULATION OF THE VMT MIX
The proportion of the total vehicle-miles-traveled (VMT) driven by a
given vehicle type depends entirely on (a) the number of vehicles,
(b) the model year registration distribution, and (c) the mileage accumu-
lation rate distribution. Also, as light duty diesel powered vehicles
and trucks become a larger proportion of their respective fleets, their
VMT proportions will increase. As the diesel powered vehicle type VMT
fractions increase, the corresponding gasoline powered vehicle type V1IT
fractions will decrease.
The MOBILE2 computer program calculates the VMT mix; unless a user inputs
locality specific information. The calculation procedure is based on the
estimated number of vehicles and the average annual miles driven for each
vehicle type. The product of these two variables estimates the total
miles driven on January 1 of a calendar year for each vehicle type. 3y
performing this calculation for each vehicle type and summing the
results, the total miles driven on January 1 for the entire highway
mobile source fleet are estimated. Finally, by normalizing the
individual vehicle type total miles, the VMT fractions are estimated.
Specifically, the MOBILE2 computer program performs the calculations in
subprogram TFCALX with the following equations:
MILES(IV) = VCOUNT(IV)*DAF(IV)*TFNORM(IV)
TOTVMT SUMiv[MILES(IV)]
VMTMIX(IV) - MILES(IV)/TOTVMT
where
TOTVMT is the total miles traveled by the entire highway mobile
source fleet.
IV is the vehicle type index (1 - LDGV, 2 = LDGTl, 3 =
LDGT2, 4 = KDGV, 5 - LDDV,' 6 = LDDT, 7 - HDDV, and 8 =
MC).
VMTMIX(IV) is the estimated VMT fraction for vehicle type IV.
VCOUNT(IV) is the estimated vehicle count for vehicle type IV based
on 1978 registrations. To use the dieselization rates,
VCOUKT(l) = VCOUNT(5) and VCOUNT(2) = VCOUNT(6). This
implies that the LDDVs and LDGVs are combined to become
the light duty vehicle fleet. Similarly, the LDGTls and
LDDTs are combined to become the light duty truck fleet.
Both the light duty vehicle and truck fleets are adjusted
by fleet sales fractions to separate the diesel from the
gasoline powered vehicles/trucks.
DAF(IV) is the dieselization rate adjustment factor for vehicle
type IV. DAF(3) = DAF(4) - DAF(7) = DAF(8) = 1.0; which
implies no dieselization adjustments are made for these

Appendix C
CALCULATION PROCEDURE TO COMBINE THE EMISSION RESULTS
OF THE TWO LIGHT DUTY GASOLINE POWERED TRUCK CLASSES
Frequently air quality analyses require the use of one light duty
gasoline powered truck vehicle type as opposed to two. However, emis-
sion factors are presented for two truck types: LDGT1 and LDGT2. As* a
result, a procedure has been developed which will combine the two truck
types. This appendix describes this procedure. The procedure simply
combines the calculated emission factors of each truck type on the basis
of VMT. To illustrate this, a hypothetical example is used.
Suppose that on January 1, 1985, the LDGT1 and LDGT2 calculated CO
emission factors are 32.57 and 22.09 grams/mile; respectively. Further,
assume that the LDGT1 and LDGT2 proportions of the total fleet VHT are
7.9' percent and 4.6 percent; respectively. Finally assume that the
entire fleet travels 4.1 billion miles.
From this example it is obvious that the combined truck types travel the
following miles on January 1, 1985:
(4.1 x 109 miles) (.079) + (4.1 x 109 miles) (.046)
Further, the total grams emitted by the combined truck types are as
follows:
(4.1 x 109 miles) (.079) (32.57 g/mi) + (4.1 x 109 miles) (.046) (22.09 g/mi)
As a result, the calculated CO gram/mile emission factor estimate for the
combined truck type is as follows (total grams/total miles):
(4.1 x 109 miles) (.079) (32.57 g/mi) + (4.1 x 109 miles) (.046) (22.09 g/mi)
(4.1 x 109 miles) (.079) + (4.1 x 109 miles) (.046)
or,
(.079) (32.57 g/mi) + (.046) (22.09 g/mi)
(.079) + (.046)
After simplifying the equation it becomes obvious 'that the combined LDGT
vehicle type is a function of the calculated emission factors and the VMT
fractions. The more generalized formula is as follows:
VMT(LDGTl) x EF(LEGTl) + VHT(LDGT2) x EF(LDGT2)
VMT(LDGTl) + VMT(UDGT2)

Appendix D
METHODOLOGY FOR CALCULATING JANUARY 1 TRAVEL WEIGHTING
INFORMATION AND FLEET AVERAGE MILEAGE ACCUMULATION
This appendix describes the derivation of January 1 registration
distributions, the annual rate of mileage accrual for the fleets, and the
fleet average mileage accumulation distributions. The January 1
registration and annual rate of mileage accrual distributions are used in
the calculation of travel weighting fractions. The fleet average mileage
accumulation distributions are used to estimate the January 1 emission
levels by model year.
D.I JANUARY 1 TRAVEL WEIGHTING INFORMATION
The travel weighting fractions for a given vehicle type are the
individual model year proportions of the total VMT for the vehicle type.
To generate the travel weighting fractions, typically three distributions
are required: (1) the annual mileage accrual rate per vehicle by age
distribution, (2) the registration distribution, and (3) the fleet sales
fraction distribution (to account for the influx of diesels).
D.I.I January 1 Registration Distribution Transformations
A portion of the January 1 travel fraction .calculation procedure is to
estimate the January 1 model year registration distribution for each
vehicle type. The model year registration distribution, frequently
referred to as the registration mix, begins with all model years combined
for a given vehicle type and apportions them into their appropriate model
year index (except for model year index 20 which represents all model
years that were built 20 or more model years ago). At this phase of the
registration mix development, the LDV and LDT model year registration
distributions are composed of both the gasoline and diesel powered
vehicle types.
For the EPA MOBILE2 computer program, the initial model year registration
distributions are assumed to be based on -July 1 data. This July 1
information is then transformed into January 1 model year registration
distributions. For vehicle types where model year sales are assumed to
begin on October 1 (light duty vehicles and trucks), the original July 1
model year registration distribution accounts for approximately 75
percent of the current model year fleet. Using the assumption of uniform
sales throughout the year, approximately 25 percent would have been sold
by January 1 (or one-third of the July 1 registration). The older model
year registration figures are six months older on July 1 than they are on
January 1. However, no direct adjustment are made to these older model
year registration figures. Although the difference between January 1 and
July 1 for the older model vehicles is primarily scrappage, the older
model year registration figures are adjusted later.
Denoting the July 1 registration fractions as R(l), R(2), R(3), . . .,
R(20+), we can generalize the January 1 adjustment equations as follows:
-------
D-2
FIRST MODEL YEAR INDEX: 1/3*R(1)
SECOND AND LATER MODEL YEAR INDEX: R(i), 1=2, 3, .... 20+
The second type of adjustment for the January 1 model year registration
distributions is to account for the fleet sales fractions: The
separation of the model year sales into diesel and gasoline powered
vehicle types. The fleet sales fractions are given in each table .48 of
Appendix E. As a result, the January 1 model year registration
distributions are adjusted according to the following formulation:
FIRST MODEL YEAR INDEX: l/3*R(l)*F(my)
SECOND AND LATER INDEX: R(i)*F(my-i+l)
F(my) is the fraction of the model year sales which are gasoline powered,
if calculating the LDGV or LDGT registration distributions. F(my) is the
fraction of the model year sales which are diesel powered, if calculating
the LDDV or LDDT registration distributions.
The last adjustment to estimate the January 1 model year registration
distributions is to normalize the distribution such that the fractions
sum to one. To accomplish this adjustment, the following procedure is
used:
DAF = SUMi[P(i)*R(i)*F(myi+l)]
where P(l) =1/3
P(l) =1 i - 2, 3 20+
R(i) « July 1 registration figures
i - 1, 2, 3, . . ., 20+
F(my-i+l) the fleet sales fraction for model year my-i+1
and SUM! = the summation over the 20 model years.
Then each January 1 registration P(i)*R(i)*F(my-i+l) figure is divided by
DAF to estimate the January 1 registration mix.
For vehicles whose model year sales begins on January 1 (heavy duty
vehicles and motorcycles), there are two changes to the above
normalization procedure. P(l) should be set to zero and every F(my-i+l)
term should be set to 1.
D.I.2 January 1 Annual Rate of Mileage Accrual for the Fleet
The last aspect of calculating the travel weighting fractions is
determination of the January 1 annual rate of mileage accrual. The
methodology for calculating the average mileage accumulation rate will be
explained by the following example: Calculation of the average annual
mileage accumulation rate for the 1985 model year (MY) vehicles on
January 1 of 1985, 1986, 1987 and later years.
First the average annual mileage accumulation rate of the 1985 MY light
duty vehicles on January 1, 1985, will be calculated (the calendar year
when the vehicle model year index is one). It is assumed that mileage
-------
D-3.
accrual is uniform throughout the year and that 1985 light duty model
year sales begin on October 1, 198A.
Using these assumptions, it is obvious that by January 1, 1985, all 1985
MY vehicles are less than one year old and accumulate mileage at the
first year rate. The annual rates of mileage accural are presented in
table .4 or .4A for each vehicle type. For the light duty gasoline
powered vehicles, the annual mileage accrual rate for vehicles during
their first year is 14,400 miles.
By January 1, 1986, those vehicles that had been sold by January 1, 1985
have been on the road for an additional year and accumulate mileage at
the second year annual rate of 13,900 miles.
In addition to the 1985 model year vehicles sold before January 1, 1985,
those 1985 MY vehicles sold after January 1 and before October 1, 1985,
must be considered. Again by assuming uniform sales, approximately 75
percent of the 1985 model year vehicles are sold after January 1, 1985.
Further, on January 1, 1986 these vehicles are still in their first year
of mileage accumulation and are accumulating mileage at a 14,400 mile
annual rate.
Since the first group represents three months of sales and the second
group represents nine months of sales, the average annual mileage accrual
rate of 1985 MY vehicles on January 1, 1986 can be expressed as follows:
(.25)*(13,900) + (.75)*(14,400)
By extension, the formula for the average mileage accumulation rate of
the 1985 MY vehicles on January 1, 1987 is as follows:
(.25)*(13,400) + (.75)*(13,900)
Denoting the average annual rate of mileage accrual during the first,
second, and third year as M(l), M(2), and M(3); respectively, the
generalized average annual mileage accumulation rate equations on January
1 are as follows:
FIRST MODEL YEAR INDEX: M(l)
SECOND MODEL YEAR INDEX: .25*M(2) + .75*M(1)
THIRD MODEL YEAR INDEX: .25*M(3) + .75*M(2)
Ith MODEL YEAR INDEX: .25*M(i) + .75*M(i-l)
For the vehicle types whose model year sales begin on January 1 (heavy
duty vehicles and motorcycles) the generalized formulae are as follows:
FIRST MODEL YEAR INDEX: 0
Ith MODEL YEAR INDEX:.M(i-l)
D.2 JANUARY' 1 FLEET AVERAGE MILEAGE ACCUMULATION
To estimate the emission levels on January 1 for each model year (as in
tables .2A through .2C for each vehicle type), the annual mileage accrual
rate per vehicle by age distribution is used to derive the fleet average
mileage accumulation distribution.
-------
D-4
The methodology for calculating the average January 1 fleet cumulative
mileages will be explained by example: Calculation of the average
cumulative mileage for the 1985 model year (MY) vehicles on January 1 of
1985, 1986, 1987, and later years.
First, we calculate the average fleet cumulative mileage of the 1985 MY
LDGVs on January 1, 1985 (the calendar year when the vehicle model year
index is defined as one).
We assume vehicle sales are uniform throughout the year, the mileage
accrual is uniform throughout the year, and the 1985 model year sales
begin on October 1, 1984.
Using these assumptions, it is obvious that by January 1, 1985 (25
percent of the way through the sales year), approximately 25% of the 1985
model year vehicles will be sold. These vehicles range in age from 0 to
3 months. Assuming uniform sales, their average age is 1.5 months.
Therefore, the average mileage accrual for these 1985 MY vehicles which
have been sold by January 1, 1985, is 1.5/12, or .125, times the annual
rate of mileage accrual for the first year. The annual rates of mileage
accrual are presented in table .4 or .4A for each vehicle type. For
LDGVs the annual mileage accrual rate for vehicles during their first
year is 14,400 miles.
By January 1, 1986, those vehicles sold before January 1, 1985 have been
on the road for an additional year. Therefore, those vehicles have
accumulated mileage for l+(1.5/12) years, or 1.125 years. Referring to
table .4A or .4 for the annual rates of mileage accrual, we can calculate
the average cumulative mileage of these vehicles as the sum of the first
year's mileage (14,400 miles) plus .125 times the second year annual rate
(13,900 miles).
In addition to the 1985 model year vehicles sold before January 1, 1985,
we must consider those 1985 MY vehicles sold between January 1, 1985 and
September 30, 1985. If we again assume uniform sales, then by. January 1,
1986 these vehicles range in age from 3 months to 12 months, with an
average age of 7.5 months. Since these vehicles are still in their first
year of use on January 1, 1986, their average mileage accumulation on
that date is 7.5/12, or .625, times 14,400 miles.
The average cumulative mileage of all 1985 MY vehicles on January 1, 1986
is the sales weighted average of the cumulative mileages for these two
groups of vehicles (those sold before January 1 and those sold after
January 1).
Since the first group represents three months of sales and the second
group represents nine months of sales, the weighted average cumulative
mileage of 1985 MY vehicles on January 1, 1986 can be expressed as
follows:
.25*[14400 + .125*13900] + .75*[.625*14400]
-------
D-5
By extension, the formula for the cumulative mileage of 1985 model year
vehicles on January 1, 1987 is given by:
.25*[14400 + 13900 + .125*13400] + .75*[14400 + .625*13900].
Denoting the average rate of mileage accumulation during the first,
second, and third years as M(l), M(2), and M(3), we can generalize the
equations for cumulative mileage on January 1 as follows:
FIRST YEAR: .125*M(1)
SECOND TEAR: .25*[M(1) + ,125*M(2)J + .75*[.625*M(1)]
THIRD YEAR: M(1)+.25*[M(2)+.125*M(3)]+.75*[.625*M(2)]
Ith YEAR: M(1)+M(2)+...-H!(i-2)+.25*[M(i-l)+.125*M(i)]+.75*[.625*M(i-l)]
For vehicles whose sales year begins on January 1 (heavy duty vehicles
and motorcycles) the formulae are modified as follows:
FIRST YEAR: 0
SECOND YEAR: .5*M(1)
THIRD YEAR: M(l) + M(2) + ... + M(i-2) + .5*M(i-l)

Appendix F
SAMPLE CALCULATION OF MOTOR VEHICLE EMISSIONS
This appendix presents the procedure for calculating emissions factors in
a step-by-step manner. Although most users of motor vehicle emission
factors should rely on computerized calculations (such as MOBILE2), this
sample calculation may prove useful to those becoming familiar with the
methodologies presented in this document.
For this sample calculation, the light duty gasoline powered vehicle
(LDGV) hydrocarbon emissions for January 1, 1985 are computed. An
ambient temperature of 80°F is assumed. Although this HC calculation is
only for the LDGVs, it is designed to give the user an understanding of
the logical sequence of calculations. The emission factor calculation
procedure of the other vehicle types follows the same logical sequence;
however, the equations may differ.
An inventory of motor vehicle sources of hydrocarbon emissions should
include emissions from the eight vehicle types. For each vehicle type
the exhaust emission factors should be calculated with the equation
presented in the corresponding chapter. The resultant exhaust emission
factors multiplied by the fraction of vehicles-miles-traveled (VMT) for
the respective vehicle types will sum to the average gram/mile exhaust
emission levels from the entire highway mobile source fleet. For
hydrocarbon emission estimates, the crankcase and evaporative HC
emissions are calculated and added to the exhaust HC emissions estimates.
F.I DATA REQUIREMENTS
Before determining what data are required, the user should review the
conditions under which vehicles are tested in order to ascertain whether
these conditions differ from the locality specific ambient temperature,
average speeds, and vehicle operating modes (see Section .A.I in each
chapter).
The user should determine the following locality specific data:
1. Ambient temperature.
2. Fraction of January 1 travel, by model year, for each vehicle
type (model year registration distributions and fleet annual
mileage accumulation rates)
3. The VMT mix.
4. Percent of VMT in cold start and hot start operating modes for
light duty vehicles, light duty trucks, and motorcycles.
5. The calendar year of study (January 1 of that year).
6. Any other data required to utilize additional (optional)
correction factors.
-------
F-2
F.2 DATA USED TO CALCULATE HC EMISSIONS
For this sample calculation, the following conditions are assumed:
1. Ambient temperature is 80°F.
2. National statistics on average fleet annual mileage accumulation
rates and vehicle registration by model year are used.
3. The total hydrocarbon emissions (as opposed to non-methane HC)
are calculated for the speed of 30 mph.
4. The percentages of VMT in the cold start, stablized, and hot
start operating modes are assumed to be 40%, 30%, and 30%
respectively, for light duty vehicles; both catalyst and
non-catalyst.
5. The calendar year of study is 1985.
6. All other conditions are assumed to match the vehicle testing
conditions.
F.3 CALCULATION OF EXHAUST EMISSION FACTORS
The equation to calculate the exhaust hydrocarbon emission factor for
LDGVs as discussed in Chapter 1, is given as follows:
BEFnpstwx - SUMi(BERipn* [NMi] *TFi*Ripstwxn*
[ACCFipt*ELCFip*TTCFip*HCF]-K:CEVi*TFln)
Since the air conditioning usage (ACCFipt), extra load (ELCFip), trailer
towing (TTCFip), and humidity level for NOx (HCF) are assumed to match
the basic test conditions, they are set equal to 1.0 (i.e., they have no
effect on the calculations and may be disregarded). Similarly, the
non-methane fraction (NMi) can be set to 1.0 since total HC emissions are
being calculated.
Only four factors are of concern in this sample calculation: (1) the
basic exhaust emission level (BERipn); (2) the model year fraction of
annual' travel (TFin); (3) the speed/temperature/operating-mode correction
factor (Ripstwxn); and (4) the crankcase and evaporative HC emission
level (CCEVi). Refer to Chapter 1 for a full explanation of the emission
factors equation.
F.3.1 Basic Exhaust Emission Levels (BERipn)
The basic exhaust emission levels for LDGVs are the emission levels per
mile; assuming the basic test conditions. The HC emission levels on
January 1, 1985 are given in Table 1.1.2A. These BERipn values are also
listed in Table F-l and will be used to calculate the tailpipe exhaust HC
emissions.
-------
F-3
F.3.2 Travel Weighting Fractions (TFin)
In order to calculate the fraction of annual travel by model year (TFin),
the fraction of in-use vehicles by model year are weighted on the basis
of annual rate of mileage accumulation. In many cases, locality specific
data on automobile use and registration are readily available. Whenever
possible, local data should be used. However, for purposes of this
sample calculation, the national average fraction of annual travel from
Table 1.1.5 will be used. The TFin values are also listed in Table F-l
to be used for calculating the exhaust HC emissions.
F.3.3 Speed/Temperature/Operating-Mode Correction Factor (Ripstwxn)
Although the speed/temperature/operating-mode correction factor can be
calculated manually using the generalized equations in Chapter 1, the
computer program, MOBILE2, was used to generate the Ripstwxn values for a
cold/stable/hot mix of 40%/30%/30%, an ambient temperature of 80°F, and
an average route speed of 30 mph. The appropriate Ripstwxn values are
listed in Table F-l.
F.3.4 Calculated Tailpipe Exhaust Emission Factors
The final step in the calculation of the tailpipe exhaust HC emission
factor for LDGVs is to multiply the mean emission levels, travel factors,
and correction factors for each model year and then sum the products.
This procedure is also shown in Table F-l depicting the calculation of a
tailpipe exhaust HC emission factor for LDGVs. The emission factor is
expressed in units of grams per vehicle mile traveled.
If the pollutant were CO or NOx, no further calculations would be needed
to estimate the total exhaust emission factor. However, for HC emission
estimates the additional calculations in Sections F.3.5 and F.3.6 need to
be performed.
F.3.5 Crankcase and Evaporative HC Emission Levels (CCEVi)
To calculate the crankcase and evaporative HC emission level, the model
year total crankcase and evaporative HC emission levels (CCEVi) are
required from Table 1.1.IB. Further, the fractions of annual travel by
model year (TFin) are required (the same as in Section F.3.2). The final
step in this procedure is to multiply the average CCEVi levels with the
annual travel model year fractions, TFin, and then sum the products.
This procedure is shown in Table F-2 depicting the calculations of the
crankcase and evaporative HC emission factor for LDGVs. The emission
factor is expressed in units of grams per vehicle mile traveled.
F.3.6 Total HC Emission Factors (BEFnpstwx)
Slimming the emission factors from Sections F.3.4 and F.3.5 will result in
the total HC emission factor. For this example the total HC emission
factor is 2.534 grams/mile (2.095 + 0.439).

Appendix 6
NATIONAL AVERAGE EMISSION FACTORS FOR HIGHWAY VEHICLES
Light duty vehicles, light duty trucks, heavy duty vehicles, and
motorcycles comprise the four main types of highway vehicles. Within
each of these types, the number of engine cycles and fuel type results in
different emission characteristics* For .example, vehicles may be powered
by either gasoline or diesel fuel.
It is also important to note that highway vehicle emission factors change
with time and, therefore, must be calculated for a specific time period.
The major reason for this time dependence is the gradual replacement of
vehicles with older emission control equipment by vehicles with newer
control equipment, as well as the gradual deterioration of vehicle
emissions as they accumulate mileage.
This appendix contains average emission factors for several calendar
years between 1975 and 1995 for various ambient temperature, cold/hot
start VMT weighting, and average speed combinations. This appendix
includes one case that represents the average national emission factors
aa generated from the basic test conditions (in Tables G-3, G-9, and G-15.
for HC, CO, and NOx; respectively) as well as other scenarios that can be
used to assess the sensitivity of the emission factors to changing input
conditions. All emission factors are given in units of grams of
pollutant per vehicle mile traveled. The hydrocarbon emission levels
include the crankcase and evaporative HC emission results. Further, the
hydrocarbon emissions are total, rather than non-methane.
Emission factors presented in this section are intended to assist those
individuals interested in compiling approximate mobile source emission
estimates for large areas, such as an individual air quality region or
the entire nation.
The emission factor calculation techniques presented in this document are
strongly recommended for the formulation of localized emission estimates
required for air quality modeling or for the evaluation of air pollutant
control strategies. Many factors, which vary with geographic location
and estimation situation, can affect emission estimates considerably.
The factors of concern include average speed, percentage of VMT in
cold/hot start vehicle operation, percentage of travel by vehicle type,
ambient temperature, air conditioning usage, vehicle load, trailer
towing, and humidity. Clearly,, the innumerable combinations make it
impossible to present mobile source emission factors for each
application. An effort has been made, therefore, to present emission
factors for a range of conditions. The following conditions are
considered for each of these cases:
1. Each table represents one average speed. There are 6 basic
tables with speeds of 5.0, 10.0, 19.6, 35.0, 50.0, and 55.0 mph.
2. Each table presents six calendar years: 1975, 1980, 1982, 1987,
1990, and 1995.
-------
G-2
3. Each calendar year presents 30 combinations of five temperatures
and six operating modes. The five temperatures are 0°, 25°, 50°,
75°, and 100°F. The six operating mode combinations (percent VMT
in a cold start, non-catalyst; percent VMT in a hot start,
catalyst; and percent VMT in a cold start, catalyst) are 0/0/0;
0/27.3/0; 0/100/0; 20.6/0/20.6, 20.6/27.3/20.6; and 100/0/100.
4. The VMT mixes are those calculated from MOBILE2. They are as
follows:
Calendar Year LDGV/LDGT1/LDGT2/HDGV/LDDV/LDDT/HDDV/MC
1975 .786/ .083/ .047/.042/.000/.000/.033/.009
1980 .781/ .083/ .047/.042/.005/.001/.033/.009
1982 .773/ .082/ .046/.042/.013/.002/.033/.009
1987 .729/ .077/ .046/.042/.056/.007/.033/.009
1990 .693/ .073/ .046/.042/.092/.012/.033/.009
1995 .647/ .069/ .046/.042/.138/.017/.033/.009
Each table presents emission factors for the 30 combinatons discussed
above for the six calendar years between 1975 and 1995. The table
entries were calculated using the techniques described and data presented
in this document. Examination of the tables indicate the sensitivity of
the emission factors to various conditions. A user who has specific data
on the input factors should calculate a emission factor to fit the exact
scenario. When specific input factor data are not available, however, it
is hoped that the range of values presented in the tables will cover the
majority of applications. The user should be sure that the appropriate
scenario is chosen to fit the situation under analysis.
