The objective of this study in to improve thermal efficiency in gasoline engines using hydrogen. Mixed combustions with gasoline and hydrogen were investigated by using a single cylinder engine. The brake thermal efficiency of hydrogen mixture combustion was higher than that of gasoline combustion at the wide range of load. At low load, 23% of the thermal efficiency was improved by using 10% hydrogen mixture. The brake thermal efficiency had no dependence on the hydrogen mixture ratio in hydrogen/gasoline mixture combustion. The cooling loss was increased with decreasing the exhaust loss and unburned loss by hydrogen mixture in gasoline combustion since the burning rate of hydrogen mixture combustion was higher than that of the gasoline combustion.
