Abstract: This report presents the impacts of triple fuel blends composed of liquefied methane-hydrogen and benzene, gasoline, hexane, toluene, iso-octane, ethyl alcohol (ethanol) and methyl alcohol (methanol) on the specifications of performance and NO formation of a spark ignition engine (SIE). A gas fuel's mass ratio has been remained constant as 50%, and mass ratio of other gas fuel has been changed between 10% and 50%. The maximum thermal and exergy efficiencies are 37.15% and 37.31% which are observed with 50% benzene-50% hydrogen combustion and minimum values of them are 20.69% and 20.61% which are attained with 50% methanol-50% hydrogen. The peak NO is attained with 50% benzene-50% hydrogen combustion as 5.78E-07 mol/cm³ and minimum NO is attained with 50% methane-50% hydrogen as 2.92E-9 mol/cm³.
