Description

a drainage structure

technical field

The invention relates to the technical field of automobiles, more specifically, it relates to a drainage structure for the oil filling port of a cylinder cover.

Background technique

In the prior art, the engine oil generally flows directly into the crankcase through the oil port of the cylinder cover. This process is generally accompanied by the generation of a large number of air bubbles and is likely to be directly spilled on the chain during the filling process; and after the oil is added, If the oil accumulates for a long time, the lack of flow will cause the oil to emulsify.

Engine oil, that is, engine lubricating oil, can lubricate and reduce friction for the engine, assist cooling and cooling, seal and prevent leakage, prevent rust and corrosion, shock absorption and buffering, etc. Known as the "blood" of the car.

Engine oil emulsification is the appearance of white emulsion and the color of engine oil turns white. Normally, the engine oil is clear and transparent. After running for a period of time, the new engine oil will turn black at most, and it is still a liquid with strong fluidity. Generally, when the engine oil emulsifies, there will be no obvious failure phenomenon in the initial stage of the vehicle.
