Timing cover lid of engine

Abstract

The invention discloses a timing cover lid of an engine, and relates to the technical field of engines. The purposes of reducing noise generated by the timing cover lid when the engine works and improving the structural compactness of the timing cover lid are achieved. The timing cover lid comprises a cover lid body, wherein an oil return hole is formed in the cover lid body; an inlet of the oil return hole is connected with an oil outlet opening of an oil and gas separator of the engine; and an outlet of the oil return hole is connected with an oil inlet of an oil return box of the engine. The timing cover lid is mainly applicable to engines of vehicles.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine timing cover. Background technique [0002] The timing cover of the engine plays a role in sealing and protecting the timing system device in the engine. Since the timing system device will generate relatively large noise during the engine working process, the timing cover can also play a role in reducing noise. [0003] However, although the timing cover can reduce the noise emitted by the timing system device, since the timing cover is a thin-walled structure with relatively poor rigidity, relatively large noise and vibration will be generated during engine operation. At present, in order to reduce the noise and vibration generated by the timing cover during engine operation, various automobile manufacturing companies have also designed timing covers with different structures, but they still cannot effectively improve the rigidity of the timing cover, resulting in low...

[0003] However, although the timing cover can reduce the noise emitted by the timing system device, since the timing cover is a thin-walled structure with relatively poor rigidity, relatively large noise and vibration will be generated during the engine operation.

At present, in order to reduce the noise and vibration generated by the timing cover during engine operation, various automobile manufacturing companies have also designed timing covers with different structures, but they still cannot effectively improve the rigidity of the timing cover, resulting in lowering The effect of noise and vibration is not satisfactory; and these structures do not fully utilize the space of the timing cover, resulting in poor structure compactness
