To reduce exhaust emission, and improve heat efficiency by providing with a fuel reformer for reforming hydrocarbon fuel to hydrogen gas, and operating a spark ignition engine with at least either one of hydrocarbon fuel and hydrogen gas.
A part of hydrogen gas generated by a fuel reformer 10 is supplied to a spark ignition engine 1 by a control signal 83, and a hydrogen distributor 14 is controlled so as to supply residual hydrogen gas to a fuel battery 11. An electric power regulator 9 is controlled by a control signal 84 so as to supply electric power of the fuel battery 11 to an electric motor 2. Gasoline is reformed to hydrogen gas by the fuel reformer 10, electric power is generated by the fuel battery 11, and the electric motor 2 is rotated. Rotating force of the electric motor 2 is transmitted to wheels 8 through a differential gear 7 by a power transmitter 6 so as to obtain driving force. Driving force of the wheels 8 is regulated in such a way that an output of a fuel pump 16 is regulated by the control signal 81, and a gasoline flow rate supplied to the fuel reformer 10 is increased/decreased.
