Effects of Gasoline Properties on Emissions From SI Engine-The Influence of Sulfur on Performance of Catalyst
Published May 16, 1995 by Society of Automotive Engineers of Japan in Japan
Event: JSAE Spring Conference
Effects of gasoline fuel volatility, sulfur content and composition on emissions were investigated using a typical Japanese vehicle. In this result, increasing sulfur content of gasoline significantly raised exhaust CO, THC and NOx emissions from the vehicle equipped with a fresh catalyst or an aged catalyst. The sulfur affected performance of catalyst, and influenced paraffins conversion more than olefins and aromatics conversions. The sulfur effect on benzene conversion was greatest in aromatics.
