Background

This section provides background information related to the present disclosure only and is not necessarily prior art.

The turbocharger is actually an air compressor that increases the intake air amount by compressing air.

Therefore, the turbocharger has remarkable improvement on the performance of the automobile engine, and is widely applied to the fields of passenger vehicles and commercial vehicles.

However, because the turbocharger of the engine is usually cooled by oil and coolant in a high-temperature and high-pressure environment, after the engine is stopped, the oil pump and the water pump are driven by the operation of the engine to stop working, and the oil and the coolant stop flowing along with the oil pump and the water pump, the temperature of the turbocharger of the engine cannot dissipate heat, so that the service life of the turbocharger of the engine is shortened, and the maintenance cost is increased.

In order to solve the problems, part of operators can idle for a period of time after stopping the engine, and the engine is stopped after being cooled, so that the damage of the supercharger can be delayed to a certain extent, but the problems cannot be solved fundamentally.

Further, the first connection portion 411 and the second connection portion 412 are both U-shaped, and the height of the first connection portion 411 is smaller than that of the second connection portion 412.

Specifically, since the crank is rotatably coupled to the displacer 21 and the power piston 22, that is, the first coupling portion 411 of the crank is rotatably coupled to the power piston 22 and the second coupling portion 412 is rotatably coupled to the displacer 21. A driving rod 4111 is disposed between the first connection portion 411 and the power piston 22, and both ends of the driving rod 4111 are connected to the first connection portion 411 and the power piston rod 222, respectively, specifically, the driving rod 4111 is rotatably connected to the first connection portion 411.
