Homogeneous charge compression ignition (HCCI) combustion can be achieved further improvement in thermal efficiency by increasing both compression and specific heat ratios. Toward the commercial production of gasoline HCCI engines, it is important to understand the effect of fuel characteristics on HCCI and SI combustion. The model fuels used in this study have the two parameter, octane number and fuel components. Using these model fuels, the effect of fuel components against two Auto-Ignition phenomena, which are 1) HCCI combustion and 2) knocking in SI combustion, was analyzed with experimental approaches.
