Claims

[Scope of utility model registration request]

It consists of a rotor having a large number of gas passages separated from each other passing through it in the direction of the rotation axis, and a case that supports the rotor rotatably around the rotation axis, and the case includes a rotor that is opposite to the end of the rotor. An exhaust inlet port connected to the engine exhaust port and an exhaust discharge port for discharging exhaust gas into the atmosphere are formed at a position offset in the rotor rotation direction, and an Pressure wave supercharging, in which an intake discharge port connected to the engine intake port is formed at a position, and an intake inlet port for sucking atmospheric air is formed at a position opposite to the exhaust discharge port in the rotation axis direction. A supercharged engine equipped with a turbocharger, comprising a bypass passage that communicates an upstream side of the intake passage with a downstream side of the supercharger, and a control valve that opens the bypass passage when exhaust gas recirculation control is performed. Features a supercharged engine.
