THE EFFECT OF FUEL HYDROCARBON COMPOSITION ON EXHAUST EMISSIONS FROM JAPANESE VEHICLES

The effect of fuel hydrocarbon composition on exhaust emission was deterined according to the Japanese statutory cycles for five Japanese vehicles using severn kinds of unleaded fuels. The effect of fuel composition on mass emissions of CO, HC and NOx is of little significance for any of the vehicles tested. The hyudrocarbon composition in exhaust gas varies substantially with the fuel composition and emission control system of the vehicles. As the fuel aromatics increase, aromatic content in the exhaust hydrocarbon fraction also increases but olefin content tends to decrease in all vehicles except the catalyst vehicle. The specific reactivity of the exhaust hydrocarbon fraction does not vary much for any vehicle except the catalyst one. /SAE/
