STUDY OF UNCONTROLLED AUTOMOTIVE REFUELING EMISSIONS

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 was found to be significant. A correlation equation was derived from the study.
