Claims

[Scope of utility model registration request]

(1) A case in which engine output is transmitted to a supercharger via a continuously variable automatic transmission and an electromagnetic clutch, and supply air is pressurized by the supercharger and supplied to the combustion chamber by the operation of a bypass solenoid valve. The system is configured such that the air may flow through an air supply passage that bypasses the supercharger and is supplied to the combustion chamber, and the continuously variable automatic transmission, the electromagnetic clutch, and the bypass electromagnetic valve are controlled according to the operating state of the engine. An internal combustion engine with a supercharger.

(2) The continuously variable automatic transmission speeds up as the engine rotates at low speeds, and when the engine is under low load, the electromagnetic clutch is disconnected and the bypass solenoid valve opens the bypass air supply passage. An internal combustion engine with a supercharger according to claim 1, which is operated as a utility model.
