Development of Internal Combustion Engine and Fuel Composition to Achieve Early Low Carbonization of Automobiles

Abstract

In order to significantly reduce CO2 emissions from automobiles, it is essential to develop technologies for improving the thermal efficiency of internal combustion engines, such as lean combustion, and fuel technologies suitable for combustion. In this study, the effects of fuel composition on lean-burn engines were verified, and by analyzing the effects, fuel characteristics that achieve both knock suppression and lean-burn limit expansion were investigated.
