EVAPORATIVE LOSSES FROM AUTOMOBILES: FUEL AND FUEL SYSTEM INFLUENCES

THE PRINCIPAL INFLUENCES BEARING ON EVAPORATIVE HYDROCARBON LOSSES FROM AUTOMOBILES HAVE BEEN STUDIED IN EXPERIMENTAL WORK AT THE BARTLESVILLE ENERGY RESEARCH CENTER OF THE U.S. BUREAU OF MINES AT BARTLESVILLE, OKLAHOMA, USA. THIRTEEN FUELS AND THIRTY-ONE VEHICLES WERE USED IN THE STUDY. HYDROCARBON LOSSES, BOTH EXHAUST AND EVAPORATIVE, WERE MEASURED DURING TESTS THAT SIMULATED TYPICAL CITY DRIVING WITH THE VEHICLES. RESULTS SHOW THAT FUEL COMPOSITION MARKEDLY AFFECTS BOTH THE AMOUNT AND CHEMICAL CHARACTER OF THE LOSSES, THE AMOUNT OF LOSS IS ALSO DEPENDENT UPON AMBIENT TEMPERATURE AND FACTORS RELATED TO THE VEHICLE. THE MANNER AND DEGREE IN WHICH THE SPECIFIC FUEL AND VEHICLE FACTORS INFLUENCE THE LOSSES ARE DISCUSSED. (A)
