Claims

[Scope of utility model registration request]

It consists of a rotor having a large number of mutually separated gas passages penetrating in the direction of the rotation axis, and a case that supports the rotor rotatably around the rotation axis, and the cable length includes:
At a position facing the end of the rotor, an exhaust inlet port connected to the engine exhaust port and an exhaust discharge port for discharging exhaust gas to the atmosphere are formed offset in the rotor rotation direction, and an exhaust inlet port An intake discharge port connected to the engine intake port is formed at a position opposite to the rotational axis direction, and an intake inlet port for sucking atmospheric air is formed at a position opposite to the rotational axis direction from the exhaust discharge port. In a supercharged engine equipped with a pressure wave supercharger of the same type, and a starting device downstream of the supercharger that bypasses the supercharger and supplies intake air to the engine when the engine is started, The passage is provided with a bypass exhaust passage that branches from the upstream side of the supercharger and bypasses the supercharger, and is provided with a valve device that opens the bypass exhaust passage during light load operation of the engine. A supercharged engine.
