Docket A-87-11 

or Project Manager JJ L /jLJ<^ 

and Support Branch /* ^ 

On April 18, 1989 a briefing was given to Dr. J.J. Liu of 

NHTSA on our application of simplified onboard refueling 

controls to a Ford Taurus vehicle. A copy of the briefing 

materials used is attached. We also showed Dr. Liu the video 

tape of our laboratory fill tests comparing the onboard car 

with a stock Taurus and other late model vehicles. 

Following the presentation, we took the vehicle on the 

road for Dr. Liu to observe fill and driving performance. The 

fueling was done at the Shell gas station at Plymouth and 

Broadway. The car was filled by Dr. Liu with no problems, even 

after multiple top-offs. Dr. Liu also fueled a stock 1989 

Buick Century. This vehicle had multiple premature shut-offs 

and would only fuel at a reduced dispensing rate (the full-flow 

dispensing rate was approximately 11.2 gallons per minute). It 

also experienced spitback at the end of the fill. Dr. Liu then 

drove the Taurus for approximately 15 minutes on both local 

streets and the US 23 expressway. At the conclusion of the 

drive, Dr. Liu commented that the vehicle drove "just like a 

normal car". He also expressed the desire to see the car 

evaluated under hot summertime conditions.

Application of Simplified Refueling 

Controls to a Ford Taurus Vehicle

Introduction 

EPA has previously applied simplified refueling controls 

to fuel systems (Figure 1) 

GH Cutlass Ciera, Spring 1988 

Ford Taurus, Fall 1988 

Both systems performed as desired 

Met proposed emission standard 

Eliminated spitback 

Excellent fill quality with fuels meeting RVP and 

dispensing rate limits of EPA proposal 

Simplification of current designs 

0 Commenters have faulted EPA vork, for not being on a car 

GM and Ford claimed system didn't work when put on a 

car 

Similar designs on API cars had several problems 

Commenters pointed to lack of purge development for 

EPA sysiem 

0 In response, EPA set out to develop a car based system

Vehicle Selection 

EPA not able to significantly alter purge system 

Therefore, necessary to find a vehicle which could handle 

onboard purge in stock configuration 

Based upon running loss testing, a Ford and a GM vehicle 

were identified 

Low running losses suggested good purge 

Testing isolated the Ford Taurus as having best purge 
P.7 

System Definition 

Current in-use conditions exceed proposed future standards 

High dispensing rates 

High fuel volatility 

Enhancements were developed to handle these conditions 

Would not be needed for future vehicles 

However, EPA desired vehicle to perform adequately 

under current conditions 

Key areas of improvement 

Reduced flow resistance for liquid seal 

Enlarged anti-spitback valve 

Enlarged rollover/vent valve 
P.8 

Components of Vehicle System 

Liquid seal by overflow tube (Figure 2) 

Less resistance at high dispensing rates 

Liquid seal down to 3 gallon/minute 

Enlarged anti-spitback valve (Figure 3) 

Located in filler pipe to allow use of overflow tube 

Production design would place at fuel tank inlet 

Enlarged rollover/vent valve (Figure 4) 

0.4" orifice 

Secondary orifice eliminated in favor-of retaining 

. existing tank vent 

Existing tank vent upgraded with production "blue" valve 

having larger vent orifice

Test Results 

0 Rollover tests of vent valve on fuel tank 

Zero leakage for left or right rollover 

0 Refueling emissions using full proposed test procedure 

well below proposed EPA standard (Table 1) 

0.07 at 4 gallons per minute 

.02 at 10 gallons per minute 

No effects on exhaust emissions or driveability 

0 Severe fuel tank slosh/carryover evaluation 

No liquid carryover to canister 

0 Laboratory finability comparisons (Table 2) 

14-15 RVP fuel, 15 gallon per minute dispensing rate 

* No spitback on onboard car 

* Droplet spray and some spitback on stock Taurus 

* Other late model cars unable to fill at these 

conditions
