Claims

[Scope of utility model registration request]

In an engine that has an air supply and exhaust system that does not overlap with each other for each of two cylinder groups and is equipped with a supercharging device, a resonance pipe is provided in the pipe on the side of the supercharging device that faces the engine, and at least one of the resonance pipes is 1. A supercharging device for an engine, characterized in that the two communicating pipes communicate with each other, the communicating pipes are provided with a valve, and control means is provided for controlling the opening and closing of the valve based on the engine speed and load.
