Engine and air cylinder head cover thereof

Abstract

The invention discloses an air cylinder head cover, which comprises a head cover at the intake side and a head cover at the exhaust side, wherein the head cover at the intake side is provided with a first containing hole for containing an oil pressure control valve at the intake side, the head cover at the exhaust side is provided with a second containing hole for containing an oil pressure control valve at the exhaust side, the air cylinder head cover is provided with an oil inlet passage, the oil inlet passage is respectively communicated with the first containing hole and the second containing hole, the head cover at the intake side is provided with an intake advanced oil outlet passage and an intake delayed oil outlet passage which are communicated with the first containing hole and a VVT (variable valve timing) device at the intake side, and the head cover at the exhaust side is provided with an exhaust advanced oil outlet passage and an exhaust delayed oil outlet passage which are communicated with the second containing hole and a VVT device at the exhaust side. The air cylinder head cover has the advantage that the oil pressure control valve and an oil path communicated with the same are arranged on the air cylinder head cover, so the installation and detachment of the oil pressure control valve are convenient, the layout of the engine is more reasonable, the structure is more compact, and the size is reduced. The invention also discloses the engine using the air cylinder head cover.

Description

technical field [0001] The invention relates to the technical field of automobile engines, in particular to a cylinder head cover of the engine. The invention also relates to an engine using the cylinder head cover. Background technique [0002] The cylinder head cover is an integral part of the engine cylinder, usually made of aluminum alloy or plastic. After it is fitted with the end face of the cylinder head, it forms a closed space, and the camshaft in the engine transmission, the front bearing cover of the cylinder head, etc. It is enclosed in it for sealing and noise reduction. [0003] Most of the existing engines adopt VVT technology (Variable Valve Timing Technology, which is the abbreviation of Variable Valve Timing in English). Or the exhaust volume, as well as the opening and closing time and angle of the valve, so that the amount of air entering can be optimized and the combustion efficiency can be improved. Specifically, the oil pressure control valve (also ...

AI Technical Summary

Problems solved by technology

[0004] The engine with VVT device is limited by the structure, so the OCV valve and the oil passage connected with it can only be arranged in the cylinder head, which makes the manufacturing and processing technology of the cylinder head more complicated and increases the purchase cost. The OCV valve and the oil channel are set on the cover, so that the layout of other structures of the engine is restricted, and the optimal layout of the engine components cannot be achieved, resulting in a larger engine volume

[0005] To sum up, how to solve the problem of unreasonable layout and excessive volume of the engine caused by the OCV valve and oil passage on the cylinder head has become an urgent problem to be solved by those skilled in the art
