In this study, ignition and combustion characteristics of biomass gas in a HCCI engine was investigated experimentally. Imitation biomass gas consisted of H_2 CH_4, CO, N_2 and CO_2, was used assuming wood pyrolysis gas. Test engine was a 3cylinder 1.6L gas engine by modifying compression ratio from 9.5 to 24 and equipping intake air heating system. Experiments were carried out by changing fuel composition and fuel/air mixture condition. As results, knocking was not occurred at higher equivalence ratio 0.4, because the fuel had much dilution components. Indicated thermal efficiency was achieved 47%. It was also clarified that H_2 advanced ignition timing but CO retarded it.
