Abstract
This utility model belongs to the field of automotive parts technology, and provides an integrated cylinder head cover, engine, and vehicle. The cylinder head cover includes: a cover body with an internal cavity; an inner cover plate connected to the side of the cover body with the internal cavity, forming an oil-gas separation channel between the inner cover plate and the inner wall of the internal cavity, the oil-gas separation channel including an inlet, a coarse separation structure, and a fine separation structure in sequence along the flow direction of the oil-gas mixture; a pressure regulating zone disposed on the cover body and located on the fine separation structure; and a gas exchange zone disposed on the cover body, one end of which communicates with the fine separation structure. Compared with the prior art, this utility model achieves efficient separation of the oil-gas mixture in the engine crankcase by constructing a cavity inside the cover body and setting an inner cover plate to form an oil-gas separation channel, and sequentially integrating the coarse separation structure and the fine separation structure inside the cover.
