Abstract
To correspond with CO2 reduction from the automobile, in conjunction with electrification, improving the thermal efficiency of ICE is crucial and lean and EGR diluted combustion are being studied. It is important to enhance combustion in lean and EGR diluted condition and it is known that the effects of fuel components are significant. In this study the effects of fuel components on the lean & EGR diluted combustion are examined with L4 engine and the fuel specifications required to enhance lean combustion are reported.
