Study of uncontrolled automotive refueling emissions. Final report

Technical Report ·
OSTI ID:6977672

Twenty-two (22) late model vehicles, representing a variety of fuel-system geometries from eight different manufacturers, were tested to determine uncontrolled refueling emissions. The effects that fuel RVP, dispensed fuel temperature, differential temperature between the vehicle's tank temperature and the dispensed fuel temperature, and fuel tank and inlet pipe geometries have on refueling emissions were studied. Three factors were found to significantly affect a vehicle's refueling emissions: fuel RVP, dispensed fuel temperature, and the differential temperature between the vehicle's tank temperature and the dispensed fuel temperature. A variety of fuel-system geometries were represented in the study, however, none were found to be significant. A correlation equation was derived from the study.
