Claims

[Scope of utility model registration request]

An engine equipped with a supercharger is provided with an air flow sensor that detects the amount of intake air in the intake passage, a rotation speed sensor that detects the engine rotation speed, and a fuel supply means for supplying fuel to the engine. is provided, receives signals from the air flow sensor and engine speed sensor, and issues a fuel cut signal when the intake passage pressure determined based on intake air amount information and engine speed information exceeds a predetermined limit value. A supercharging prevention device for a supercharged engine, characterized in that a supercharging prevention control means for outputting the fuel to the fuel supply means is provided.
