Nonroad Engine Population Estimates
Report No. NR-006e
July 2010
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 final NONROAD2008a 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. Relative to the
previous December 2005 version of this report, this version includes population estimates for
high performance sterndrive and inboard (SD/I) recreational marine engines.
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, 1999, or 2000, 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
1
-------
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, 50-75 hp, 75-100 hp, 100-175 hp, 175-300 hp, 300-600 hp,
600-750 hp, 750-1000 hp, 1000-1200, 1200-1500 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 final
NONROAD2008a. A table containing descriptions of each SCC can be found in Appendix B.
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, final NONROAD2008a uses the 2003 version of the PSR estimates
of national populations1, 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 PSR estimates are described in detail in later sections of this report.
Depending on the equipment application, the 2003 version of PSR includes population estimates for the years 1996,
1998, 1999, and 2000.
-------
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 spark-ignition (<25 hp other than
snowmobiles, off-road motorcycles, and all-terrain vehicles) 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 certain other applications may be either mobile or stationary, and, thus,
may be subject to different regulations. Therefore it was necessary to estimate 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. 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, for fractions of engines used in mobile nonroad
equipment 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 in order to avoid counting stationary sources in the nonroad mobile sources
inventory. The model input populations, which are shown in Appendix A, have already been
-------
reduced according to the percentages shown in Table 2 to represent only the portions of these
applications considered to be mobile equipment.

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
continue to be used in final NONROAD2008a. (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-005d) 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 III 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 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 III, IV, and V were primarily 2-stroke gasoline engines, so they were
assigned SCCs of 2260xxxxxx. Engine classes I and II 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 III, IV, and V, and 4-stroke conversion factors were used for
engine classes I and II.
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 CNG, gasoline, or diesel
fuel. Assuming diesel equipment makes up roughly half of these remaining forklifts leads to a
total population of SI forklifts of 442,000. (12) Draft NONROAD2002a and later model
versions therefore use this estimate for the 1996 base year SI forklift population. The 1998 PSR
data was then used to subdivide the SI forklifts, such that propane accounts for about 85 percent,
CNG about ten percent, and gasoline fueled equipment roughly five percent of the SI forklifts.
-------
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 non-central 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. It should be noted that the use of 100% LPG/CNG for large SI
generators was based on recent sales and other market data. Due to the lack of such data for
compressors and other large SI equipment, the 50% default value was used for these equipment
types.

* For forklifts the 95% is split roughly 85% LPG and 10% CNG.
In a prior version of the model (draft NONROAD2004), populations in the 50-100 hp bin
were entirely assigned to either the 50-75 hp bin or the 75-100 hp bin, depending on the average
hp of the 50-100 hp bin. Since final NONROAD2005, these populations are distributed to the
50-75 hp and 75-100 hp bins based on the PSR population data, and new population-based
average hp estimates are calculated for each bin. This change should have little effect on
emissions.
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.
11
-------
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 final
NONROAD2008a. (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 final NONROAD2008a. Based on sales information, 67 percent are 2-stroke
engines and 33 percent are 4-stroke engines.
The population of ATVs used in final NONROAD2008a 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
Versions of NONROAD prior to NONROAD2005 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. Since final NONROAD2005, however, the model 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 2003
update of the PSR sales estimates through year 2000 (15) were used in conjunction with the
latest input values for load factor, activity, median life and the default scrappage curve to
calculate the 2000 base year populations for CI equipment. The 2000 populations are a sum of
equipment in operation from model years 1950 through 2000, based on a backcast extrapolation
of sales from 1973.
12
-------
Recreational Marine Equipment
The 2000 PSR population estimates were used for the base year of the recreational
marine equipment category. Since final NONROAD2005, the power distribution of the
population estimates for outboard and personal watercraft engines were reevaluated using the
projected sales reported in the 1998-2004 model year certification data. This results in higher
average rated power estimates for these categories compared to previous versions of the model.
Similarly, for stern drive/inboard engines, the available California certification data for 100-600
hp engines were used to update the power distribution for these engines, since the manufacturers
certifying in California make up more than 90 percent of sterndrive/inboard sales. This also
results in higher average rated power estimates compared to versions prior to final
NONROAD2005.
Previous versions of NONROAD did not include high-performance SD/I marine engines.
Manufacturers have more recently commented that approximately 1,500 high-performance
engines are produced in the U.S. per year. These engines range from 500 to 1500 horsepower
and are used in both racing and non-racing applications. Based on conversations with individual
high-performance engine manufacturers, we estimate that about two thirds of these engines are
sold for use in the U.S., with an average power of about 650 horsepower. These engines are
designed to sacrifice service life for power, but with rebuilds, generally are used for 7-8 years
(we use 8 years for our modeling). Based on these estimates and the growth rate in the model,
we estimate a 1998 population of SD/I engines over 600 horsepower of 7500 units. (16)
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. (17,18) 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
13
-------
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 substituted into 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.
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 separate category, and the sailboat
auxiliary diesel engines were of a design providing low horsepower similar to that of outboard
engines rather than inboard engines. There is little distinction between inboard and outboard for
sailboat activity, allocations, or any other parameter, so assigning these sailboat auxiliary
engines to outboard rather than inboard is a moot issue.
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. Final NONROAD2008a uses a
sales-weighted average hp for each equipment type/hp category that was generated using
information from PSR. For diesel equipment the average hp inputs come from the same 2003
PSR sales information for 1990-2000 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.
