Although Homogeneous Charge Compression Ignition (HCCI) engines are expected both higher thermal efficiency and lower NOx emission, they have problems of its operation under high load region and of its ignition control. We have applied EGR to HCCI combustion of natural gas for stationary use in order to enhance the engine power successfully. This paper describes effect of EGR inhomogeneity on HCCI combustion using a single cylinder experiments with various EGR supply methods. The experiments showed that inhomogeneity of the composition and the temperature of the mixture affect the ignition timing and combustion duration significantly, and which indicates mixture inhomogeneity have possibility for control of HCCI combustion.
