Description of the Related Art In a conventional piston type internal combustion engine, an increase in output is measured by absorbing air exceeding the volume of the combustion chamber or a mixture of air and flammable liquid fuel (hereinafter referred to as mixture) into the combustion chamber. In this case, there is a supercharger that uses supercharged air driven by an exhaust turbine and takes out the rotational force directly from the crankshaft and supercharged by mechanical drive. There was a problem in the durability of the engine because there was only an increase in the air or the air-fuel mixture and the condition was very severe as compared with the non-turbo engine.

である。By taking advantage of the two cycles, high output can be obtained at low speed. By sending a large amount of compressed air into the combustion chamber immediately after the explosion, it has the effect of promoting secondary combustion of exhaust gas and reducing the emission of nitrogen oxides into the atmosphere. If the internal combustion engine has three or more cylinders, it can be used like a conventional internal combustion engine.
