An engine assembly includes an air inlet pipe having an air inlet, an air supply port, and an air return port. The air inlet communicates with air. The air supply port communicates with an air inlet manifold of an engine. In a length direction of the air inlet pipe, the air return port is located between the air inlet and the air supply port. An air inlet control valve is disposed on the air inlet pipe, and located between the air inlet and the air return port. An exhaust gas return pipe communicates with the air return port. An exhaust pipe communicates with the exhaust gas return pipe and an exhaust manifold of the engine. In the length direction of the air inlet pipe, a distance S between the air return port and the air inlet control valve and an inner diameter D of the air inlet pipe meet S/D≤2.

Exhaust gas recirculation system, engine assembly, and vehicle

An oil pump is provided. The oil pump comprises: a shell; a rotor mounting part on the shell and having a rotor supporting structure; and a rotor mechanism disposed on the rotor mounting part. The shell has an inlet and an outlet and defines a low-pressure oil chamber and a high-pressure oil chamber. A partition wall is disposed between the low-pressure oil chamber and the high-pressure oil chamber for separating the low-pressure oil chamber and the high-pressure oil chamber. An engine cover comprising the oil pump and an engine comprising the engine cover are also provided.

Oil pump, engine cover and engine comprising the same

An oil pump is provided. The oil pump comprises a shell, a rotor mounting part on the shell, and a rotor mechanism disposed on the rotor mounting part.
