An experimental study was performed to clarify the operation condition on natural gas fueled homogeneous charge compression ignition engine. Using a single cylinder engine, operation range, engine performance and exhaust emissions were measured under various intake air temperature, compression ratio and equivalence ratio. Under the high intake air temperature, combustion efficiency is high, but under lower temperature, engine was operated in narrow A/F range. The use of high compression ratio, engine was operated at lower intake air temperature. To keep combustion efficiency over 80% and NO x emission under 10 ppm, maximum in-cylinder temperature should be controlled within the narrow range between 1 500 K and 1 800 K. Natural gas auto-ignited over 1 000 K and the effect of A/F was low. Auto ignition temperature was decreased according to the decline of intake air temperature.
