This invention is one of a reciprocating internal-combustion engines. Because former engines have the maximum pressure of combustion when piston and crank arm are on a straight line, it gives only large mechanical stress on the engine, and thermal and work efficiencies are reduced. This invention, finishing the 4-stroke cycles within 2 stroke-period promotes the work and thermal efficiencies, decreases the weight and volume per unit power and saves energy by the active use of exhausted heat because ignition is done at the large fixed crank shaft angle after T.D.C. where the rotative force is very large. It is, therefore, suitable to ship, heavy equipment, bus, truck, train and generators that need high power and is suitable for cars and especially airplanes that need small weight and volume per unit power. |
