PROBLEM TO BE SOLVED: To completely burn gasoline so as to reduce the exhaust emission concentration and improve fuel cost by supplying natural gas or hydrocarbon fuel with a low boiling point to an injection area for gasoline to be exploded and burnt. SOLUTION: Gasoline is supplied from a gasoline tank 10 through an adjust valve 11 to a carburetor 2 provided at an air intake port 3 of a combustion chamber 5. At this time, the gasoline is heated above about 30 deg.C by electric heat from the combustion chamber 5. When natural gas or gasoline gas from the carburetor 2 is compressed in a gasoline injection rear of the combustion chamber 5, gas is ignited at a high temperature, combustion flame is instantaneously transmitted to an injection area of the liquid gasoline, and injected liquid gasoline is quickly and uniformly vaporized over the whole injection area. Thus, ignition is performed in the air-fuel mixed state to explosively cause combustion so that gasoline can be completely burnt. The previously heated gas or natural gas is thus fed in with the air so as to improve combustion efficiency and decrease the concentration of black smoke and exhaust gas.
