The invention discloses a cylinder head cover for an engine. The cylinder head cover comprises a cover main body, and a containing groove is formed in the top of an inner cavity of the cover main body; the open end of the containing groove is connected with a mounting bottom plate to form an oil-gas separation channel; an opening communicating with the oil-gas separation channel is formed in one end of the mounting plate, so that an oil-gas inlet is formed, and an exhaust pipe is arranged on the side wall of the cover main body; a plurality of labyrinth type oil-gas separation walls are arranged at the end, close to the oil-gas inlet, of the bottom of the containing groove in the length direction at intervals, and the other end of the mounting bottom plate is connected with a separation assembly; an oil return channel used for communicating the separation assembly with an inner cavity of the engine is arranged on the mounting bottom plate; and a transition cavity communicating with the oil-gas separation channel is further formed in the end, close to the exhaust pipe, of the cover main body, and a diaphragm valve is arranged at the open end of the transition cavity. The cylinder head cover for the engine is simple in structure and convenient in machining and assembly; and effective oil-gas separation can be achieved, and the oil content of gas exhausted through the exhaust pipe is reduced.
Description
technical field [0001] The invention relates to the technical field of engines, in particular to a cylinder head cover for an engine. Background technique [0002] The cylinder head cover for the engine is a cover that covers the engine block, which can prevent external impurities from entering the engine, and at the same time play a role of sealing. The engine cylinder cover is generally connected to the cylinder head by bolts so that it can cover and seal the cylinder head and keep the engine oil inside the engine. In addition, the high-temperature gas generated by the engine during operation will escape into the crankcase through the gap between the piston group and the cylinder, causing blow-by. The components of blow-by gas are unburned fuel gas, water vapor and exhaust gas. Water vapor condenses in the engine oil to dilute the engine oil and reduce the performance of the engine oil; the sulfur dioxide in the exhaust gas is oxidized by the air to form sulfuric acid, w...
