Specifically, the engine is the heart of an automobile, and the engine is provided with a plurality of metal surfaces which rub against each other, and the parts have high movement speed, poor environment and high working temperature, so that lubricating oil needs to be added into the engine. The lubricating oil can play roles of lubricating, reducing wear, assisting in cooling, sealing, preventing leakage, preventing rust, preventing corrosion, damping, buffering and the like on the engine, and the service life of the engine is prolonged.

The oil return passage 1 is used for returning the lubricating oil of the cylinder head to the oil pan so as to ensure the amount of the lubricating oil in the oil pan.

The cylinder cover belongs to a valve actuating mechanism and is mainly used for sealing the upper part of a cylinder to form a combustion chamber. And is used as a support for the camshaft and the rocker shaft as well as the air inlet and outlet pipes. In order to prevent the abrasion of the components such as the camshaft, the rocker shaft and the like in the motion process and cool the camshaft, the rocker shaft and the like, a channel for lubricating oil to flow is arranged in the cylinder cover.

The oil baffle plate 2 is arranged at the oil pan, and the oil baffle plate 2 is used for ensuring that engine oil of the oil pan is at a normal liquid level when the engine passes through different road conditions so as to ensure the oil absorption function of an engine oil pump of the engine.

The one-way valve 4 is a valve which can only flow along the water inlet and can not return the medium at the water outlet. In this application, lubricating oil can only flow to the oil pan direction through check valve 4, and the oil-gas mixture in the oil pan can not flow back.

The path of the oil return passage refers to both ends of the oil return passage 1 and a portion between both ends of the oil return passage 1. The engine is through set up on the route of oil return route check valve 4 can prevent in the oil gas mixture in the oil pan recoil to the cylinder cap from oil return route 1, has reduced the gas mixture and has smugglied machine oil secretly to the combustion chamber and burn, has avoided the lubricating oil return in the cylinder cap not smooth, can reduce the machine oil consumption of engine to and the emission of engine has been reduced.

In one embodiment, the one end of the oil return passage 1 connected to the oil baffle 2 is provided with the check valve 4.
