OFFICE OF 

SEP 6 1988 AIR ANO RADIATION 

Mr. Samuel A. Leonard -

Director, Automotive Emission Control 

Environmental Activities Staff 

General Motors Corporation 

General Motors Technical Center 

Warren, Michigan 48090 

Dear Mr. Leonard: 

Running loss emission measurements are provided in the 

enclosure in response to your request to Richard Wilson, dated 

July 1, 1988. These running loss measurements are preliminary 

results from EPA's ongoing test program. The running loss test 

program was described in the June 30, 1988 workshop on 

evaporative and refueling test procedures. A copy of the 

workshop handout on the running loss program is also enclosed. 

More vehicles have been tested for running losses since 

the workshop. The enclosed information includes data on twelve 

vehicles. This represents all currently available information. 

Please let me know if you have any questions regarding the 

materials in this package. 

Sincerely yours, 

,£*'s \Sr-y..-*>yi *y

Running Loss Test Program 

The enclosed data are preliminary and subject to further 

data validation. The data are highly variable. The fuel tank 

temperatures on some of the tests are significantly lower than 

the target tank temperatures. The running losses also may be 

low on those tests. EPA plans to continue running loss testing 

for several weeks. Care should be taken in interpreting the 

results until further data has been collected and all the data 

are validated.

"Init" canister weight was normalized 

prior to preconditioning for each seq. 

"End" canister weight after completion 

of dyno procedure. 

Fuel Temp Rises are change in 

fuel tank temperature from 

start of test (following DHB) 

to end of Bag 3, 4 and 6. 

Nominal fuel start temperature 

is same as ambient Test Temp. 

(Diurnal fuel heating from 

20 degrees below test temp to

All tests with a diurnal prior to LA4s 

Small subset of tests both with and without diurnal 

0 Diurnal Temperatures - 75 to 95°* rise, 60 to 80° rise 

0 Cell Temperatures - 95°- 80° 

0 Fuels - 11.7, 10.4, 9.0, 7,0* RVP

Original target - 15° rise after 3 bags 

Current target - 15° rise after 3 bags, 22° after 6 bags 

0 Standardize Canister Weight Before Each Prep 

Using 11.7 RVP fuel and 80°F, base is the weight following 

the LA4, 1 hr. soak, LA4, 1 hr soak 

* The 7 0 RVP fuel test has only one set of temperatures 

which are 95° cell temperature and 75° to 99° diurnal
