ABSTRACT:
A hybrid electric vehicle which is driven by a motor powered with electric power generated by an engine, wherein the cylinder, piston, and sub-combustion chamber of the engine have insulation structure so that heat sufficient for evaporating fed fuel is held in the sub-combustion chamber. The sub-combustion chamber having a central communicating orifice is formed on the central portion of the piston head, a fuel collision table is formed in the sub-combustion chamber, and a plurality of radial communicating orifices for jetting flame from the sub-combustion chamber against the cylinder is provided, the burning is easy even with using a low pressure fuel injection mechanism, therefore a solenoid valve type injection pump with simple structure is used, the burning is smooth with using alcohol fuel such as methanol and ethanol, the fuel injection timing is adjusted dependently on load to the optimal timing, the number of working cylinders is controlled so as to match to the load, the control allows the engine to operate at the optimal fuel consumption, therefore emission of hazardous substance contained in exhaust gas is minimized. The engine of the present invention needs no cooling mechanism, and also needs no heavy gear box and no clutch mechanism, the weight of the whole vehicle is significantly reduced comparing with conventional vehicles, the fuel consumption is reduced also in terms of the light weight.
