Abstract: This paper presents basic combustion characteristics of a spark-ignition engine fuelled with three kinds of gaseous fuels; H_2, CO and CH_4. A single-cylinder engine was operated under WOT at 1500min^<-1> condition. CO gas gives lower thermal efficiency than H_2 and CH_4, since the energy of the fuel can not be transferred to the pressure or the work, although it gives higher combustion temperature which makes the higher exhaust gas temperature and much higher NO_x emissions than those for CH_4. H_2 gives upper limit of flammability due to the occurrence of backfire and almost comparable thermal efficiency with that for CH_4 at its stoichiometric condition.
