PROBLEM TO BE SOLVED: To largely improve the efficiency of an engine by using methanol as the fuel of an engine, increasing the enthalpy of exhaust gas with the combustion chamber of the engine as a heat-shielding structure, and providing a turbocharger and a turbine in an exhaust tube. SOLUTION: The outside of an engine 1 formed at a combustion chamber of ceramics and the outside of an exhaust passage formed as a heat-shielding structure, methanol is used as fuel, and the shaft of a main generator 2 is coupled to a crankshaft. A turbocharger 3 and a turbocharger generator 31 are provided at the heat-shielded exhaust tube, intake air is compressed by the thermal energy of the exhaust gas of the engine 1, and a turbine 4 is driven by the exhaust gas to drive a sub-generator 5. The generating powers of the generator 2, the sub-generator 5 and the generator 31 are used to control the operations of axle motors 71, 72 and the charging or discharging of a capacitor 10 and a battery 11 by a controller 6. The catalyst 12 of the intake port of the engine 1 is heated by an electric heater 13, and the methanol is modified to dimethyl ether having high cetane number. |
