置。[Claims for Utility Model Registration] A bypass passage is provided in the turpin of the supercharger, and a waste gate valve that opens and closes via an actuator that operates according to supercharging pressure is installed in the bypass passage. In a supercharged engine that is equipped with a boost pressure switch that shuts off fuel injection when boost pressure becomes excessive in the pressure passage that detects the intake pressure downstream of the compressor, the intake pressure of the supercharger is detected. 1. A fuel cutoff device for a supercharged engine, characterized in that a delay valve is provided in a pressure passage to cut off fuel injection for a certain period of time when supercharging pressure exceeds a set value.
