A fundamental study has been made on the combustion process of homogeneous mixtures of air and methane, propane, n-butane and isobutane using a pancake-type constant volume combustor with the final goal of developing a natural-gas-fueled spark ignition engine with high thermal efficiency and low exhaust emissions. Combustion process measurements were made by schlieren photography, the laser beam deflection method and the analysis of pressure development which enabled determination of mass fraction burned curves and burning velocities. Elucidated were the effects of charge pressure, temperature and additives of propane, n-butane and isobutane in methane, under stoichiometric and lean conditions. The effect of charge dilution by burned gases was also clarified.
