Claims

[Scope of utility model registration request]

a mechanical supercharger that is driven by the engine and compresses the air supply of the engine; a turbo supercharger that is driven by using the exhaust gas of the engine as a working medium and compresses the air supply of the engine; a first air supply passage; a first air intake valve that supplies air into the cylinder of the engine through a second air intake passage; and a second air intake valve that supplies air into the cylinder through a second air intake passage; During operation, air is supplied into the cylinder through the first and second air supply valves from both the first air supply passage communicating with the mechanical supercharger and the second air supply passage communicating with the turbo supercharger. is supplied, and a strong swirl is generated due to the pressure difference between the intake air supplied from both intake valves.
Both the and second air supply passages are communicated with the turbocharger, and supply air of approximately equal pressure is supplied from the turbocharger into the cylinder via the first and second intake valves, thereby creating a weak swirl. A supercharged engine characterized in that the supercharged engine is configured to generate a supercharged engine.
