The invention provides an automobile engine air cylinder cover. The automobile engine air cylinder cover comprises an air cylinder cover body (1) and a cylinder cover oil chamber (4), whereon a cylinder cover bolt hole (2), an oil return hole (3) and an oil return channel (5) are formed in one side of the air cylinder cover body (1), and the lower end of the oil return channel (5) is communicated with a crankshaft box. The upper end of the oil return channel (5) is communicated with the cylinder cover oil chamber (4) through the oil return hole (3), and projections of the oil return hole (3) and the cylinder cover bolt hole (2) on the plane perpendicular to the central line of the cylinder cover bolt hole (2) are overlapped at least partially. The embodiment of the invention further provides a corresponding automobile engine and a corresponding automobile. By means of the automobile engine air cylinder cover, the corresponding automobile engine and the corresponding automobile, space required by the engine air cylinder cover can be decreased, accordingly the size of the air cylinder cover is decreased, and the total size of the engine is decreased.
Description
technical field [0001] The invention relates to an automobile engine component, in particular to an automobile engine cylinder head, an automobile engine and a corresponding automobile. Background technique [0002] The engine cylinder head belongs to the gas distribution mechanism, which is mainly used to close the upper part of the engine cylinder and form the combustion chamber. At the same time, it also acts as a seal to prevent engine oil from leaking, so that the engine can be lubricated normally. Usually, an oil return passage is arranged on one side of the cylinder head oil chamber, and its function is to allow the oil in the cylinder head oil chamber to flow back into the crankcase. When the engine is running, it not only ensures that there is a certain amount of oil in the cylinder head oil chamber, but also prevents the cylinder from leaking. The oil level in the cover oil chamber is too high; there is an air passage arranged on the other side of the cylinder head...
