Characteristics of homogeneous charge compression ignition (HCCI) combustion using dimethyl ether and methanol-decomposed gas were experimentally analyzed. This research controlled ignition timing in HCCI combustion by varying a ratio of a high cetane number fuel and a high octane number fuel. Dimethyl ether was employed as the high cetane number fuel and methanol-decomposed gas, mixture of 67% hydrogen and 33% carbon monoxide, was as the high octane mumber fuel. Both dimethyl ether and methanol-decomposed gas can be reformed from methanol in endothermic reactions using exhaust heat of engines. The experiments were made with several equivalence ratio, proportions of the fuels and compression ratio. The results show that the HCCI combustion with dimethyl ether and methanol-decomposed gas has high thermal efficiency over a wide operational range.
