Homogeneous Charge Compression Ignition (HCCI) and Premixed Charge Compression Ignition (PCCI) combustion are combustion concepts, which offer simultaneous reductions in both NOx and soot emissions from internal combustion engines. However, increasing of dependence on chemical reactions to ignite and combust fuel makes controlling the combustion difficult. So far we consider that the bigger cetane number fuel has, the shorter the ignition delay becomes. On the other hand, the possibility of existence of state in which lower cetane number mixture represents shorter ignition delay is reported from recent analysis of chemical reaction using numerical calculation. In this study, combustion experiment of various cetane numbers fuels was carried out using Rapid Compression Machine (RCM) which simulated compression ignition combustion. Experiment results shows experimentally low cetane number represents short ignition delay time.
