一种发动机气缸盖罩制造技术

本实用新型专利技术公开了一种发动机气缸盖罩，该气缸盖罩的本体为塑料注塑件，在该气缸罩的外表面及内表面设有保护层。通过采用塑料注塑件的气缸盖罩，不仅可以降低发动机整体重量以及降低发动机噪音，而且制造成本低，能降低发动机的整体成本。为了有利于曲轴箱内的废气进行油气分离，在该气缸盖罩上设有迷宫式油气分离装置，位于该气缸盖罩的本体空腔内，迷宫式油气分离装置中的迷宫与该气缸盖罩为同质一体构成，容易成型，工艺性较好。（*该技术在2021年保护过期，可自由使用*）

Cylinder head cover of engine

The utility model discloses a cylinder head cover of an engine, wherein, the body of the cylinder head cover is a plastic injection molded part, and a protective layer is arranged on the outer surface and the inner surface of the cylinder cover. By adopting the cylinder head of plastic injection parts, not only the overall weight of the engine can be reduced, but also the noise of the engine is reduced, and the manufacturing cost is low, and the overall cost of the engine can be lowered. In order to facilitate the exhaust gas in the crankcase oil and gas separation, the cylinder cover is provided with a labyrinth type oil-gas separating device, the body cavity in the cylinder cover, labyrinth type oil-gas separating device in the maze and the cylinder head cover, as one homogeneous easy molding process, good.
