Engine cylinder cover shield

The utility model relates to the technical field of internal combustion engine fitting devices, and in particular relates to an engine cylinder cover shield. The engine cylinder cover shield comprises a breather, a cylinder cover shield body and a shield cover plate, wherein the breather is provided with a breather cover, a breather air outlet pipe, a gas cyclone cavity and a breather oil return passage; the cylinder cover shield body consists of a breather shell and a guide plate, a front division plate, a rear division plate and a cylinder cover shield body air outlet which are arranged on the breather shell; the shield cover plate is provided with an oil-gas inlet and an oil return port. The engine cylinder cover shield adopts a circuitous oil-gas separation passage, so that the structure is simple, the oil-gas separation path is extended, the oil drop adsorption area is enlarged, and the oil-gas separation effect can be effectively improved. Meanwhile, the cylinder cover shield body and an oil-gas separator are integrated by adopting engineering plastics, so that the manufacturing difficulty is reduced, and the manufacturing cost is reduced, thus the purposes of facilitating manufacturing and having a good oil-gas separation effect are achieved on the whole, and the pollution of waste gas emitted by an engine to the environment is relatively low.
