~his document officially .revises previous mctile source 

emission factors which ve~e ~resented in Supple1ent No. 5 to 

AP-42, Corpilation of Air Pollutant Emission 

Factors(Dece1her, 19;5). !n mid-19~8 this documEnt will b~ 

published as a Supplement to AP-U2, at which time additional 

explanatory matErial, revised type~et, renumbered tables, 

and other format changes will be made. 

!his dccument does not revise all infottation in 

Supplement Ne. 5. In particular, updated factors are not 

included for liqht-duty diesel automobiles, light-duty 

diesel trucks, off-road sources, or aircraft; net is any 

information included on particulates. 

AP-42 will te revised periodically via new su~plements 

if measured emission factor values, as determinEd through 

in-use vehiclE testing progtams (assembly line and 

surveillance testing) , and FtOjEcted emission factors, as 

estimated from testing of prctotype vehicles and from 

chanqes to statutory motor vehicle emission standards vary 

from the estimates contained in this document. 

A. Dat! ~£!!!~~ To answer the question of how ~ell 

vehicles perfor• in actual us~, EPA has administered a 

series of Exhaust emissicn surveillance progrars. ~est 

fleets of consumer-owned vehicles within varicus major 

cities are selected by model year, make, engine size, 

transmission, and carburetor in such proportion as to be 

representative of both the normal rroduction of each model 

year and the contribution of that mcdel year to total 

_,_ 

vehicle miles traveled. In the case of heavy-duty vehicles, 

fuel -type and gross vehicle weight' were ·also ·key · items in 

the stratification scheme. 

""he data collected in these rtogruis are analyzed to 

provide mean eaissions by 

·calendar year, chanqe in emissfons wftli the accumulation of 

mileage, change in emissions with the accuai-ulat·icn cf· age, 

percentage of vehicles 6~mplying with standards, and effect 

on em£ssions of vehicle ~arameters (~riginj di~Flacement, 

vehicle ~eigbt, etc.). ~heEe ~orveillance ·d~ta~ along with 

prototype v~bicle test data, assemtly line ·test data, and 

technical judgment, form ·the tasis for the existir.g and 

pro1ected motile source emissicn fact~rs presentEd iri this 

aoc"u11e rit. 

. . 

~he moet recently published results of the emission 

factor program are available in a sum•ary repcrt, 

•Automobile Exhaust Emission Surveillance Analysis of the FY 

19~q Progra1•, EPA-460/3-7€-01 9, Envircnmental Frotection 

Agency, o~sAtC/ECTD, Ann Arbor, ~ichigan 48 0~. Both the 

EPA emission factor surv.eillarce program ana the EPA 

regulatory program depend on a valid test procEdure over 

which represEntative urban emissions can be measured. At 

the present timE, EPA bas twc test procedur~s: one for 

light-duty vehicles (LDVs)--including cars, light trucks, 

and motorcycles--and one for heavy-duty vehicles fHDVs). 

~bese procedures are discussed in subsequent chaftErs. 

For localized pollu~ants such as co, the ability of the 

test procedure to pre~ict changes in emissions depends on 

the similarity of the localized driving pattern and 

-'2­
assoeiat~d cperating conditions to tbo~e in the test 

procedure. The EPA therefore has developed a ~eries of 

correction factors to expand u~on the LOV and EDV test 

procedures and tc predict emiseicne frcm a large number of 

user• specific scenarios.. r:ata required to deve I,op t bese 

correction factors have been generated using carefully 

desiqned statistical studies which test ccnsu•er-o~ned 

vehicles. 

B. lY!R.Q..§~. ~his current revisicn to previous mctile source 

emissicn factors is necessary for several reasons~ 

1. 	~hese numbers reflect test data from a much larger sam~le of in-use vehicles in all vehicle categories 

than was available previcu~ly. 

2. 	 ~ew data on catalyst-equipped (~cst- 974) 

automotiles are available, requiring sigr.ificant 

revisicn of pr~viously projected emission factors. 

3. 	 Additicnal correction factors and tEvised 

correction factors for a wider range of cc~ditions 

are now available. 

4. 	 EPA haE prom~lgated new standards for ligbt-du~y 

trucks, heavy-duty vehicles, motorcycles, and 

light-duty vehicle ar.d light-drty truck evaECtative PtdE~icns. · 

5. 	 Vehicle emission standards for several vehicle 

cateqories hav• been revised ty the Clean ·Air Act 

Amendments of 197~ (Putlic !av 95-95). 

-3­
: 	 ~ . c. 	 th•~ content or 

~his document· diff~r from A~~ql, Supjlement Ne~ S, in 

several vays: 

1 • 	 Both actual and projected emissi~D tacte~e are ~resented in one table for all calendar. years fer 

each pcllutant. Previouslyr this information Va! ~resented .in separate tatles for each .. calendar 

year. · ".'he revised tables shculd be easier tc use. 

2. 	 :n additicn to tabled emission values, the 

eguatiens used to generate the tables are included 

to increase the ease of automating the E~ission 

inventcry process. 

3. 	All vehicles are no longer assumed to travel 10,000 

miles per year. :nstead, the national aweraqe 

mileaqe accumulation. rates are used, result1n9 in 

vehicle miles traveled (Vl''!) greater than 10,000 

miles ~er vear for newer vehicles and decrea!ing 

mileage accumulati~p as.vehicles age. 

4. 	 Detericraticn of exhaust emissions is assu111ed to 

continue beyond the first ten years cf the 

vehiclE's eperatin9 life. 

5. 	 ~he emission standards for each model year vehicle 

and the derivation.of ap~rcpriate emi~sicn rates 

are given in appendices. 

6. 	Emissicn factors specific to California and highaltitude areas are ccntained in separate i:arts of 

this. dccument.

A. :n!IQQ]£~12n~ Because of their videsprPad u~e, lightdutv vehicles (automobiles) are responsible fer a large 

share of air pollutant emissions in many areas of th~ Unit~d 

~tates. ~ub~tantial research effort has be@r. expended to 

accuratc.ly characterize emissicns from these vehicles. 

E?A's Emissicn Factor Proqram (!r~) was instituted a numb~r 

of years ago in order to ~stimate emission levels of in-use 

v~hicles fer area-wide urban scenarios. 

:~ addi~ior. to the methodologies present~d for 

calculatinq co, HC, and ~ex e1haust ~missions, data are 

qiven later in this chapter for etissions in the idle mode 

and for c=ankcase and evaporative hydrocarbon emissions.

speeds and loads with a hot start and a hot statilized 

phase. Since emissicns from these tests are net equivalent 

to on-the-road emissicns, regression equaticns were 

developed sc that on-the-road emissions (SA~F) could be

~he Sar. Antonio Foad ?.oute (SA?~) located in San 

·Antonio, ~exas, is ~.24 miles long and includeE freeway, 

arterial, and lccal/collector highway segments. A ccnstant 

volume sampler is carried en beard each of the test vehicles 

for collecticn of a proportional ~art of the exhaust gas 

from the vehicle. !his sample is later analyzed to yield 

mass emission rates. Because the SA~? is an actual road 

route, the average speed varies depending en traffic 

conditions at the time of the test. !he average speed tends 

to be arour.d 20 mi/hr, with about 20, of the time spent ~t 

idle. ~he test procedure e1issicn factor iE composed 

entirely of warmed·up vehicle operation. Eased on 

preliminary a~alysis of vehicle opera~ior. data, almcst all 

heavy-duty vEhicle operation is under warmed-up ccnditicns. 

At this time, it is not known whether the ~A~~ 

accura~ely represents averaqe urban H~V driving patterns.

within the urban environmentr it is not surprising that the 

truck and cat schedules are similar. How~ver, the SAP~ (and 

the current LDV F~P) makes no attempt to account for the 

time that trucks spend idling as a result of deliveries, 

special o~erations (buses, garhaqe trucks), auxilia~y pcw~r

Thus, it is possible that the final HD cycle that is 

developed ir. future rulemakin9 will have a higher· idle 

percentage and a lover average ~peed than the SA~'· Since 

the operational data have not yet teen completel, analyzed 

and trucks have not been tested on transient cycles 

developed from the operaticnal data, the tabled emission 

factor estimates are based on the SAFP driving schedule. 

Data were assembled from tvc major sources: 

1 • 	 The emission factors contracts involving testing of 

35 gasoline and ten diesel in-use heavy-duty trucks 

by chassis dynamometer versions of the Federal Test ~rocedure (FT~) as well as over the ~an Antonio ~oad 

Poute (SAPP). 

2. 	 The emission factors (sensitivity study) of 19 

gasoline and 12 diesel in-use heavy-duty trucks. 

!hese vehicles were also tested by chassis versions 

of the FTP and over various experimental sequences (bot~ steady state and transient cycles). SA?P 

estimates were obtained ty using linear regressions 1 based on data source • 

~ther in-use heavy-duty vehicle and engine data which 

are available were not incor~orated because they were either 

not sampled usir.g current testing methcdclcgy (e.g.r 

gasoline 9-mcde concentration data whicb are net directly 

convertible to mass emissions) er vere ccllected on 

potentially non-represer.tative engines (e.9., er.9ines witb

A. :n~~gducti~.!l:. Motorcycles, which are not generally 

considered an im~ortant source of air pollution, have become 

more popular, and their nurbers have been steaa11y 

increasing in the last few years. ~he majority of 

motorcvcles are powered by either 2­ or u-stroke air-coclea 

engines; howevei, water-cooled motorcycles and Wankelpowered mctorcvcles have recently been introduced. Until 

recently, the ~redominant use of 4-stroke motorcycles was 

for on-highwav use, while the 2-stroke motorcycles were 

pred~~ina~tly for off•hiqhway u~e. ~his differ~nce in use 

was primarily a reflectio~ of significant weight and pcw~r 

variations between available 2• and 4-stroke vehicles. As 

light-weight 4-strokes and more po~erful 2-strok@s become 

available, the relative number of motorcycles in each engine 

cateqory mav char.ge. Currently, the nationvide FOpulation

calculation of Reqional Hydrocarbon Eaissio1s 

ftoa 8otor Vehicles 

This appendi• to the [evised •otor •eh1cle e•ission 

factoc docu•ent presents one pcocedute for calculating 

re9ion•ide pollutant eaissions in a step-by-step manner. 

Although most usecs of ~otor •ehicle e•ission factors should 

rely on co•puterized calculations, this sa•ple calculation 

•ay prowe useful to those •ho are beco•ing fa•iliarized with 

the 	•ethodologies pre~ented in this docuaent. 

For tbis saaple calculation we calculate light-dutr 

•ehicle hydrocarbon eaissioms for a ~uly day in 1'80. Ye 

assuae an ambient te•perature ot aoo r. Although this HC 

calculation is not coapleteo it is designed to 9iYe the user 

ao understanding of the logical sequence of calculations. 

In inweotory of motor vehicle soarces of b7drocarbon 

emissions s~ould include e•issions froa the four priocipal 

vehicle categories: li9bt-duty wehicles(auto•ot:iles); light,­

duty trucks; hea•y-duly gasoline-powered wehiclea; and 

heavy-duty diesel-powered vehicles. For each Yebicle 

category the coaposite exbausi eaission fa~tor equation 

presented in tbe corresponding chapter &bould be solYed. 

The resultant co•posite emission tactors. •ultiplied by the 

•ehicles •iles of travel (IRT) foe the respectiYe vehicle 

categories. yield the hydrocar~on exhaust e•issions fro• the 

wehicle groups. Fo~ tot~l hydrocarbon eaission est~••tes. 

the crankcase and e•aporative HC eaissions •usl also be 

C-2 

calculated aad added to the.exhaust HC e•issio11S esti•ates. 

Before deter•ining Hhat data are required. the user 

&bould re•iew the FTP conditions under which •ehicl~s are 

tested in order to ascertain vhethet these conditions differ 

fro• the area-specific a•bient te•perature. aweraqe speeds, 

and vehicle operating •odes. (See lntrodactions to Chapters 

I. 	II, III. and IV). 

The user should determine the following area-specific 

1. 	Ambient teapetature. 

2. 	Age-specific percent of annual travel tor each 


vehicle category. 


l. 	The VftT or vehicle counts and link lengths bJ 

•atious transient speed categories (e.g.. bJ 10 

•ph 	increaents). 

• '· 	Percent of YftT in cold start and bot start •odes 


lot light-dutJ vehicles and light-dut1 trucks. 


~. Any other data required to utilize addition•l. 


optional correction factors. (for th:is sa•ple 


calculation. all otb~r tactors are assu•ed to

For this sample calculation. the follovinq conditions 

are applicable: 

1~ AabieDt te•pelatate is 800 F. 

j• 	lational sta~istics on average annual ~ileage and 

vehicle re9istration by model 1ea1 will be used. 

J. 	The bydlocarbon eeissions ~ill be calculated for 

only one speed category (30 mph). In actGalitr. 

e•issions shogld ~e calculated for selected speed 

categories. an 

associated ttip len9th. From traospottation data 

fro• our hypothetical region. the awerage trip 

length for a speed of 30 aph is 6 ailes. 

~. The percentages of YftT in the cold, stable, and 

bot transient modes are assuaed to be '01, Joi. 

and 30:. respectively, for li9bt-duty Yehicles. 

both catal1st and non-catalyst~ 

The calculation ot the co•posite ezhaust hydrocarbon 

emission facto1 tor light-duty vehicles. as discussed in 

Chapter 1. is 9iven by:

Since the correction factors for air-conditioning ~sa9e 

(lip). wehicle loading ( Lp) , and tr a i 1 er to 11 i 119 (Oipw) are 

assu•ed to be equi•alent ~o the FTP conditions, they ace set 

eq~al to 1 0 0 (i.e., t~ey h~we no effect on the calculations 

and •ay be disregarded}.

Only three factors are of concern in this saaple 

calculation: (1) the FTP •ean e11ission factor (C'ipn) ; (2) 

the fraction of annual t ra•el tP1111); and (3) tbe correction 

factor fot speed. te•perature, and •ehicle o~erating •odes 

(Ripst1n). lefer to Chapter I for a full e1:planation of the

The tables auabeted -2. -3. and -~ in each chaptet of 

this docu•ent pr•sent tbe emission factors for calendat 

yeats ''70 tbtougb 19950 For each calendar 1ear. aodel-year 

specific e•issioa factors ate ptesented lot tbe 20 aost 

recent •odel reats. 

The eaission factors fot a 91ven model rear ate assuaed 

to watJ lineatlJ with aileage. Since the eaission factots 

foe a giwen aodel 1ear webicle ate calculated for July 1 of 

each calendar year it is necessacy to know the awer19e 

cueulatiwe aileage on July 1 of each calendat 7eat. 

The cuaulatiwe ailea9es ace ptesented i• Tables 1-sa. 

II-Sc. II-Sd. IIl-Sa,Il-Sa, and 1-~a. 

The aethodology tor calculating awerage cuaalatiwe 

aileage •ill be esplained by reference to a specific 

ezaaple: calculation of the ayecage cuaulatiwe eileage fot a 

1978 •odel 1eac webicle on JulJ 1 of 1978. 1,7,, 1980. and 

late11: years. 

First. •e •ill calculate th• awera9e cu•ulatiwe aileaqe 

of a 1978 Rt LDY on JulJ 1 of 1978. the calendar 1ea11: when 

the •ehicle age is defined a& 1 year. 

We assaae that the wehicle sales distribution is 

constant year• that the rate of •ileage 

acetual is constant throu9bout the rear. and tba t the 1978 

sales year begins on oct~ber 1. 1977. 

Usin9 these asau•ptions. it is obwious that bJ Joly t. 

1978 (J/qths of the way thtough the sales 7ear) 

appto•i•ately lSI of .the "78 •odel year webi cl•s ha-we been 

c-2 
sold. These •ehicles range in age fro• 0 to 9 •onths. 

lssa•in9 a constant sales distribution. thei1 awerage age is 

~.s •oaths. 

Therefore. the aweraqe •ilea9e accrual for these 1978 

"' webicles which ha•e been sold by July 1. 1978 is -.S/12~ 

or .37S ti•es the annual rate o1 •ileage accrual for tbe 

fitst year. the annual rates ot •ileage accru•l ire 

presented in Tables I-5 through ¥-~ for each Yehicle tfpe. 

1or LD's t•e annual •ileage acc~ual rate tot •~hicles dGrin9 

tbeir first 1e~r is 1~~00 •iles. 

BJ July 1. 1979. those vehicles that had beea sold bJ 

Joly 1. 1978 •a•e beea on the road tor an additional year. 

therefore. those •ebicles hawe accu•ulated •ileage for 

1•(~.5/12) 7e1rs. or 1.37~ years. Beterrinq to T•ble I-5 

for the aa1ual rates ot •ileaqe accroal. we can calculate 

the awera9e CQ•ulati•e •ilea9e of these wehicles as the sua 

of the first year•s aileaqe, 15900. plus .375 ti•es the 2nd 

J••r annual rate of 15000 •iles. 

In additiom to the 1978 •odel yeac •ehicle6 sold befoxe 

July 1. 1978, we •ust consider those 1978 ft! Yebicles sold 

bet~een Jaly l. 1978 and Sept. 30. 1978. If~• are again 

assu•in9 a uniter• sales distiibqtion, then by Jqly 1, 1979 

these •ehicles canqe in age fro• 9 •onths to 12 •ontbs. and 

thef have an a•erage age of 10.s •ontbs. Since these 

wehicles are still in their ficst 1ear of use on July 1. 

1979, their aYetage •ileaqe accu•ulation on that date is 

10.5/12, or .e1s. tiaez '~900 •iles. 

The a•erage cu•ulative •ileage of all ''18 ft1 webicles 

G-3 

on July 1r 1979 is the weighted aTerage of the cumulative 

•ileaqes foe these two groups of •ehicles (those sold b~foxe 

July 1 and those sold a[ter July 1). 

Since the first group represents 9 aontbs of sales and 

the second qroap represents 3 aonths of sales, t~e vei9hled 

a•eraqe cumulative •ileaqe of 1978 "' vehicles on July 1, 

1979 can be eapressed as follows: 

(l/11) (1~900 • (.37!1} 15000) • (1/li) ((.875) 15900) 

B.y extension. the,for•ula tor the cu11ulatiTe mileage of 

1978 aodel year vehicles on July t, 1980 is given by: 

(l/q) (15900 • \5000 • (.375) 11~000) • (1/16) psgoo + (.87~) 1SOOO) 

and so on. 

Denoting the average rate of •ileage accu•ulation 

during the ficst, second, and third years as vl, v2. and vJ, 

we can generalize the equations for caaulative •ileage on 

July 1 as follows: 

FIRST TEAB: (.l75)vl 

S£CO•D IEAR:(J/11) (vl + (.375)v2) • (1/16) ((.875)w1) 

TRIRD YEAR: (3/'I} (wl t Y2 • (.375)vl) + (1/11) (v1 • (.87S)v2). 

and so on. 

For wehicles ~hose sales year be9ins on January 1 

(bea•J d.aty trucks and •otorcycles) the for•ulas are 
•odified as follows: 

FIRST l!AI: {1/•)v1 

SECOID JEU: ( 1/2) (• 1 + ( 1/4) v2} t (1/2J ( {3/li) v 1) 

THIRD TEAJi: (l/2) (wt t v2 t (1/•)•1) t (1/2) (v1 + (3/11)•2)
