Nonroad Engine Population Estimates
Report No. NR-006b
revised December 4, 2002
Assessment and Standards Division
EPA, Office of Transportation and Air Quality
Purpose
The purpose of this memorandum is to document the source of the nonroad engine
population values used in EPA's draft NONROAD2002 emission inventory model. Engine
populations are provided as default values in EPA's NONROAD emission inventory model
categorized by equipment type, power level, and fuel type. This categorization allows the
NONROAD model to determine the phase-in of new emission standards and other unique
aspects of emissions or allocations by application, fuel type, or power level.
Introduction
The default base year application populations are used as a starting point to estimate
future and past year engine populations in the NONROAD emissions model. The base year is
either 1996, 1998, or 1999, depending on the application. The base years are the most recent
years for which population data are available. The NONROAD model tracks engines rather than
equipment because present and planned nonroad emissions regulations focus on engines instead
of equipment. EPA anticipates that future nonroad emission regulations would also focus on
engines.
The engine populations were divided into many applications because of the variety of
ways nonroad engines are used. This variety of applications allows for application-specific
geographic and temporal allocations, activity, emission rates, and other input factors to
characterize nonroad engine usage and emissions.
The engine populations were also divided into 5 fuel types: diesel (2 and 4-stroke
combined), gasoline 2-stroke, gasoline 4-stroke, compressed natural gas (CNG) (2 and 4-stroke
combined), and liquid petroleum gas (LPG) (2 and 4-stroke combined). The diesel, CNG, and
LPG engine populations for 2 and 4-stroke engines were combined because these engines exhibit
little difference in emission rates between 2 and 4-stroke engines, most likely because these
engines use fuel injection to deliver the fuel to the combustion chamber. Gasoline 2 and 4-stroke
engines were separated because of the availability of information indicating widely different
-------
emission rates, especially for hydrocarbon emissions. Each combination of application and fuel
has been assigned a unique "Source Classification Code" (SCC).
The engine populations by application and fuel were further divided into 19 power level
categories to account for emission regulations and some technology differences associated with
power level. The power level categories provided were 0-1 hp, 1-3 hp, 3-6 hp, 6-11 hp, 11-16
hp, 16-25 hp, 25-40 hp, 40-50 hp, 50-100 hp, 100-175 hp, 175-300 hp, 300-600 hp, 600-750 hp,
750-1000 hp, 1000-1500 hp, 1500-2000 hp, 2000-3000 hp, and 3000+ hp. While this detailed
disaggregation by application, fuel type, and power level allows users to make fine distinctions in
understanding the effects of control strategies, it also might lead to very small engine populations
for some states for some application and power segments.
Appendix A provides the default base year national populations used in draft
NONROAD2002.
Equipment Inventory Changes and Classifications
Previous equipment population estimates in the Nonroad Engine and Vehicle Emission
Study (NEVES) were provided by Power Systems Research (PSR), an independent marketing
research firm. (1) NEVES used 1989 in-use year estimates from PSR. The PSR population
estimates were determined from engine manufacturer sales surveys, experimentally determined
engine life, and surveys of usage of these engines. The population estimates were verified by
equipment owner surveys over the course of several years. A review and evaluation of the PSR
methodology was later provided by Pechan, another independent contractor. (2) The NEVES
work led to development of source category codes (SCCs) for given applications.
Appendix B describes both significant and minor changes between the SCCs in the
NEVES report and the NONROAD model. New equipment classes and power range additions
for some equipment types were included in the NONROAD model, altering the engine
population estimates. LPG and CNG engines, which were not included in NEVES, were added
to the NONROAD model. New SCCs were added to accommodate these new engines. There
were other minor changes that did not affect engine populations but rather changed the
description of the codes.
For many categories, draft NONROAD2002 uses updated 1998 PSR estimates of national
populations, but, as described in the report on geographic allocation, the model uses other
methods to allocate populations to the state and county level.(3) The exceptions to the use of
1998 PSR estimates are described in detail in later sections of this report.
PSR developed engine population estimates for 2 and 4-stroke diesel, gasoline, liquid
petroleum gas (LPG), and compressed natural gas (CNG) engines, categorized by application
codes. These populations were further divided by power level for the NONROAD model to
-------
determine appropriate fleet turnover rates and appropriate engine emission standard phase-in
strategies.
Appendix C describes how the PSR application codes correspond to the source
categorization codes (SCCs). Each source category is uniquely identified with an SCC, which is
a ten-digit number. The SCC number conventions are summarized in Table 1. The first two
digits, 22, represent mobile sources. For most categories, the next two digits represent the engine
or fuel type (60, 65, 67, 68, and 70, represent 2-stroke gasoline, 4-stroke gasoline, LPG, CNG,
and diesel, respectively). The next three digits represent the segment type (for example,
recreational or construction). The last three digits represent the specific kind of equipment (for
example, golf carts or snowmobiles). If the last three digits are zero, it is implied that all
equipment types in the segment are included.

In order to apply the emission standards for small (<25 hp other than snowmobiles, off-
road motorcycles, and all-terrain vehicles, which are not regulated currently) and recreational
marine spark-ignition engines, the 2 and 4-stroke gasoline, LPG, and CNG engines were
combined into one category (while still maintaining power level distinctions). The new emission
standards intend to produce cleaner engines in part by reducing the number of 2-stroke in favor
of 4-stroke engines. The reasons for combining these engines, and the associated problems, will
be described in more detail later in this report.
Mobile and Stationary Nonroad Engines
One challenge in preparing a mobile source inventory is that engines used for generators,
pumps, compressors and other applications may be either mobile or stationary, and, thus, may be
subject to different regulations. Therefore it was necessary to determine the fraction of engines
used as mobile and stationary emission sources. The NONROAD model estimates emissions
from 'mobile' equipment. The legal definition of a mobile nonroad engine is an engine that
moves from one place within a 12-month period. (4) In some cases the distinction may not be
clear because engines that might appear stationary are in fact considered as mobile. For example,
a palette-mounted engine is easily moved from one site to the next with a forklift or other type of
lift truck over the course of several months. To account for mobile nonroad engines, EPA used
the only information available which was derived from a report to the California Air Resources
Board by Booz, Allen, and Hamilton (5) and given in Table 2 to provide fractions of engines
used as mobile nonroad engines for the few application classes in which some of the engines are
used and regulated as stationary sources. Hydro power units, irrigation sets, generator sets,
pumps, compressors, and welders were the applications which were determined to have some
stationary engines. The fraction of mobile engines was applied to the equipment populations for
the appropriate applications as provided by PSR in order to avoid counting stationary sources in
the nonroad mobile sources inventory.

Small (<25 hp) Spark-Ignition Equipment
Most small (<25 hp) spark-ignition engines fall under EPA regulations targeting mainly
hydrocarbon emissions. (4,6,7) The regulations define new engine classes (I through V) based on
use (handheld versus nonhandheld) and displacement, while the NONROAD model classifies
engines by application and power level. For the purposes of inventory modeling, the five classes
are defined by application and power level. Table 3 describes the definitions of engine class by
application and power level that were used in the NONROAD model.
The 1998 PSR population estimates were used for small (<25 hp) SI equipment, except
for the following applications: lawn mowers, trimmers/edgers/brush cutters,
leafblowers/vacuums, and chain saws. The methodology for calculating the base year
populations for these four applications is described below. (Recreational equipment will be
discussed in a separate section.)
As of 1998, engines less than 25 hp used in gasoline-fueled nonroad equipment (such as
lawn and garden equipment) were required to meet the first set of Federal emission standards,
known as Phase 1 standards. Using sales estimates submitted to EPA by manufacturers of small
nonroad engines as part of their Phase 1 certification, EPA estimated the total number of engines
sold in 1998 in four of the highest sales volume small engine applications: lawn mowers,
trimmers/edgers/brush cutters, leafblowers/vacuums, and chain saws. For 1993 and earlier years,
EPA used sales estimates that had been submitted for those years by manufacturers during the

development of EPA's Phase 1 rulemaking. For the years 1994 to 1997, EPA linearly
interpolated between the 1993 and 1998 sales estimates for each application. Using this year by
year sales information and the expected scrappage of small nonroad equipment, EPA estimated
the total 1996 calendar year population for the four applications noted above. In order to
determine the power category specific populations, EPA relied on the fractions of engines in each
engine class based on the certification sales estimates for all categories other than lawnmowers.
For lawnmowers, nearly all of which were certified as Class I engines, EPA used the power
category fractions in the PSR database. The resulting 1996 base year populations were used in
draft NONROAD2002. (8,9)
Two important issues regarding small (<25 hp) SI engines and equipment require further
discussion: treating commercial and residential users separately, and accounting for the effects
of new regulations.
Many of the small spark-ignited engines are used in lawn and garden equipment
applications, and lawn and garden equipment is used both by commercial and residential users.
The commercial users are grounds keepers for golf courses, nonresidential buildings, large
apartment complexes, and some single-family homes. Commercial equipment therefore has
significantly different usage than residential equipment in terms of hours per year as well as
hours per weekday versus weekend day. To account for these differences in equipment usage,
separate SCCs were defined to account for commercial and residential lawn and garden
equipment. The 1998 PSR population estimates and the 1996 population estimates for the four
lawn and garden applications described above were divided into residential and commercial
fractions as shown in Table 4. For applications not shown in Table 4, 100% commercial use was
assumed for the engines because these applications include such categories as construction,
agricultural, commercial, and many other applications already considered commercial.
From information derived by California (10), the sales fraction combined with the
average life (in years of average operation shown in another report, NR-005B) of the engines was
used to calculate an in-use population fraction of residential and commercial equipment. The
calculation uses the sales fraction multiplied by the average life for both residential and
commercial equipment and the population fraction determined from the two populations as
shown in the equation below.
Commercial Population Fraction = (Commercial Sales Fraction * Commercial Average Life in Years) /
(Commercial Sales Fraction * Commercial Average Life + Residential Sales
Fraction * Residential Average Life)
The above methodology was applied for all applications in Table 4 with the exception of
trimmers/edgers/cutters, chain saws, and leafblowers/vacuums. Based on discussions with
manufacturers during the Phase 2 rulemaking process, we believe that the residential/commercial
split for these three applications is strongly dependent on engine class. We now classify all these
equipment powered by Class HI two-stroke engines as residential. Equipment powered by Class

IV two-stroke engines is now predominantly classified as residential. The Class IV split was
estimated based on input from the three largest manufacturers of commercial equipment (i.e.,
ECHO, Stihl, and Husqvarna) and production estimates from all manufacturers of Class IV
chainsaw engines. We now also classify the four-stroke engines over 6 hp as commercial
equipment. (11)
The regulations to be proposed require reduced emission rates in future years, and, among
other consequences, are estimated to reduce the number of two-stroke engines sold in favor of
four-stroke engines. With the current NONROAD modeling methodology, it was not possible to
keep the 2-stroke and 4-stroke spark-ignition engines in separate SCCs in the emissions model
and account for the shift of 2-stroke to 4-stroke engines. Therefore, spark-ignition engines of
less than 25 horsepower (except for snowmobiles, offroad motorcycles, and ATVs, which are not
regulated currently) were lumped into one SCC category, eliminating the SCC distinction
between 2 and 4-stroke gasoline, LPG, and CNG engines. The SCC description was changed to
reflect the new engine classes described in Table 3. The distinction between 2 and 4-stroke
gasoline, LPG, and CNG engines will be maintained for sales fraction and emission rates by
using technology groups within the SCC.
One problem with lumping 2-stroke and 4-stroke engines together is that the different
engine types have different conversion factors for converting total hydrocarbons (THC) to other
hydrocarbon types (TOG, NMHC, NMOG, and VOC). This problem was ameliorated somewhat
by defining the population to be primarily 2-stroke or primarily 4-stroke fuel types. In the base
year, engine classes of in, IV, and V were primarily 2-stroke gasoline engines, so they were
assigned SCCs of 2260xxxxxx. Engine classes I and n are primarily 4-stroke gasoline, therefore
they were assigned SCCs of 2265xxxxxx. This means that 2-stroke hydrocarbon conversion
factors were used for engine classes HI, IV, and V, and 4-stroke conversion factors were used for
engine classes I and n.
Large Spark-Ignition Equipment
The 1998 PSR population estimates were used for large SI equipment, with the exception
of forklifts. We are using different population estimates for forklifts based on a recent market
study. That study identified a 1996 population of 491,321 for Class 4 through 6 forklifts, which
includes all forklifts powered by internal combustion engines. Approximately 80 percent of
those were estimated to be fueled by propane, with the rest running on either gasoline or diesel
fuel. Assuming an even split between gasoline and diesel for these remaining forklifts leads to a
total population of SI forklifts of 442,000. (12) Draft NONROAD2002 therefore uses this
estimate for the 1996 base year forklift population.
Analysis and assumptions regarding refueling methods was necessary in order to establish
fuel type distributions in the absence of other data. Some applications of nonroad SI equipment
face much different refueling situations. Lawn and garden equipment is usually not centrally
fueled and therefore operates almost exclusively on gasoline, which is more readily available.
-------
Agriculture equipment is predominantly powered by diesel engines. Most of these operators
likely have storage tanks for diesel fuel. For those who use spark-ignition engines in addition to,
or instead of, the diesel models, we would expect them in many cases to be ready to invest in
gasoline storage tanks as well, resulting in little or no use of LPG or natural gas for those
applications. For construction, general industrial, and other equipment, there may be a mix of
central and noncentral fueling, and motive and portable equipment. We therefore believe that
estimating an even mix of LPG and gasoline for these engines is most appropriate. The
approximate distribution of fuel types for the individual applications used in the NONROAD
model are listed in Table 5.

Recreational Equipment
Recreational equipment consists of snowmobiles, off-road motorcycles, all terrain
vehicles (ATVs), golf carts, and specialty vehicle carts. The 1998 PSR population estimates
were used for golf carts and non-diesel specialty vehicle carts.
The 1998 PSR population estimates were not used for snowmobiles, off-road
motorcycles, ATVs, or diesel specialty vehicle carts. For snowmobiles, a study done by the Oak
Ridge National Laboratory (ORNL) estimated the total snowmobile population for 1999 based on
state registrations. They also developed a methodology for estimating the number of
snowmobiles unregistered in each state, which works out to be approximately five percent of the
total. Thus, they estimate a total snowmobile population of 1,567,000, which is used in draft
NONROAD2002. (13) The International Snowmobile Manufacturers Association (ISMA) also
estimated the total number of snowmobiles by summing the total number of registered
snowmobiles in those states that require snowmobile registration. However, they did not
estimate the number of unregistered snowmobiles. Therefore, we use the value presented by
ORNL as the estimate of total snowmobiles. The distribution into hp categories was based on
the hp category fractions in the PSR database.
For off-road motorcycles, the only source is the Motorcycle Industry Council (MIC).
MIC projects a total population for 1998 of 1,196,000 off-road motorcycles nationwide (13),
which is used in draft NONROAD2002. Based on sales information, 67 percent are 2-stroke
engines and 33 percent are 4-stroke engines.
The population of ATVs used in draft NONROAD2002 for the 1998 base year is
3,910,000. This estimate comes from a 1998 Consumer Products Safety Commission study. (14)
Populations of diesel specialty vehicle carts are estimated per the methodology presented
below for compression-ignition equipment in general.
Compression-Ignition (CD Equipment
Past versions of NONROAD used PSR's population estimates directly. The PSR
population estimates are derived using PSR's estimates of equipment sales, load factor, activity,
median life, and a default scrappage curve used to estimate the percent of equipment in operation
with age. Draft NONROAD2002, however, incorporates a number of significant changes that
affect the CI equipment inventory, including load factor and median life estimates. In order to
maintain consistency between the revised inputs for load factor and activity used in the model
and the load factor and activity inputs used to derive base year population estimates, the 1998
PSR diesel populations were not used. Instead, the latest PSR sales estimates (15) were used in
conjunction with the latest draft NONROAD2002 input values for load factor, activity, median
life and the default scrappage curve to calculate the 1998 base year populations for CI equipment
11
-------
used in draft NONROAD2002. The 1998 populations are a sum of equipment in operation from
model years 1948 through 1998, based on a backcast extrapolation of sales from 1973.
Recreational Marine Equipment
The 1998 PSR population estimates were used for the recreational marine equipment
category.
The LPG and CNG recreational marine engine population values were estimated to be
zero, which was confirmed with the PSR estimates. There were some diesel recreational marine
engines not covered by the emissions regulations for spark-ignition marine engines and therefore
not included in the recreational marine estimate just described.
Recreational marine spark-ignition engines fall under EPA regulations targeting mainly
hydrocarbon emissions. (16) The regulations require reduced emission rates and, among other
consequences, are estimated to reduce the number of 2-stroke engines sold in favor of 4-stroke
engines. With the current NONROAD modeling methodology, it was not possible to keep the 2-
stroke and 4-stroke spark-ignition engines in separate SCCs in the emissions model and account
for the expected effects of the regulations. Therefore, spark-ignition engines are lumped into one
SCC, which eliminates 2- and 4-stroke distinctions.
As with small gasoline engines, one problem with lumping 2-stroke and 4-stroke
recreational marine engines into a single SCC is that the different engine types have different
conversion factors for converting total hydrocarbons (THC) to other hydrocarbon types (TOG,
NMHC, NMOG, and VOC). This problem is ameliorated somewhat by defining the population
to be primarily 2-stroke or primarily 4-stroke fuel types. For outboard (SCC 2282005010) and
personal water craft (SCC 2282005015), the primary engine type in the base year is 2-stroke; for
inboard engines (SCC 2282010005), the primary engine type in the base year is 4-stroke. The
NONROAD model uses these primary engine types as the basis for the conversion factors for
these SCCs.
As presented in Appendix A, three types of recreational marine equipment are
differentiated: inboard, outboard, and personal water craft. The NEVES report documents three
types of recreational applications; inboard, outboard, and sterndrive. Since sterndrive vessels use
the same engines as inboard vessels, the EPA no longer considered the sterndrive category to be a
unique application and eliminated it. Personal water craft, sometimes known by the brand name
Jet Ski, were added to what was formerly the sterndrive category, and the SCC description was
changed accordingly.
Sailboat auxiliary propulsion engines are also included in the outboard and inboard
engine categories. The national estimates include these engines, so NONROAD does not use this
category to avoid double counting. PSR estimates that these engines only represent a small
percentage of recreational marine engines.
12
-------
The population of diesel recreation marine engines provided in the default engine
populations was derived from the PSR estimates and uses SCCs of 22820200xx. The 'xx' here
denotes inboard as '05', outboard as '10', and sailboat auxiliary as '25.' The categories of' 15'
and '20' were not used because sterndrive is no longer a category, and the sailboat auxiliary
diesel engines were of a low horsepower design resembling outboard engines rather than inboard
engines. There is little distinction between inboard and outboard for activity, allocations, or any
other parameter, so assigning these sailboat auxiliary engines to outboard rather than inboard is a
moot issue.
Note that the population values shown in this report for diesel recreational marine engines
are expected to decrease slightly in the next version of the model, based on setting the median
life to an equivalent of 25 years, which is less than the current median life hours at full load, load
factor, and activity inputs would generate.
Average Horsepower (Hp) Estimates
As seen in Appendix A, the base year population estimates in NONROAD are provided
by equipment type/hp category. In order to calculate an emissions inventory, the average hp
corresponding to each equipment type/hp category is required. For draft NONROAD2002, a
sales-weighted average hp for each equipment type/hp category was generated using information
from PSR. For diesel equipment the average hp inputs come from the same 1999 PSR sales
information that was used for the engine population calculations. For SI equipment the average
hp inputs come from the same 1998 PSR Partslink database from which most of the SI
equipment populations were obtained. The resulting average hp estimates are also provided in
Appendix A.

1 Inputs for ATV's and offroad motorcycles are set to allow calculations based on g/mile emission factors
instead of g/bhp-hr. Thus the hp values shown here do not represent the actual in-use hp of these engines.
2 The base year for swathers should be 1998. This will be corrected in the next version of NONROAD.
3 Diesel recreational marine populations are expected to change in next version due to different median life.
