Abstract

The invention relates to an integrated cylinder head cover and an automobile engine. The integrated cylinder head cover includes a cover body, a camshaft mounting seat arranged in the middle of the cover body, a solenoid valve mounting seat and a variable valve mounting seat respectively provided at both ends of the cover body, and a first lubricating oil passage structure and the second lubricating oil channel structure; the first lubricating oil channel structure includes the camshaft delivery oil channel in the middle of the cover body, the camshaft lubricating oil channel on the camshaft mounting seat, and the variable valve The variable valve lubricating oil passage on the mounting seat, the camshaft lubricating oil passage and the variable valve lubricating oil passage are all in communication with the camshaft delivery oil passage; the second lubricating oil passage structure includes a solenoid valve located at the end of the cover body The delivery oil passage, and the solenoid valve lubricating oil passage located on the solenoid valve mounting seat. The invention can solve the problem in the related art that after the cylinder head cover is integrated with VVT, VVL and other mechanisms, the demand for engine oil is increased, which leads to the deterioration of the lubricating condition of the camshaft.

Description

technical field [0001] The invention relates to the technical field of automobile engines, in particular to an integrated cylinder head cover and an automobile engine. Background technique [0002] As the country's requirements for automobile fuel consumption and emission performance become more and more stringent, the automobile industry is also making continuous progress, and more and more new technologies are applied to automobile engines at the same time, such as VVT (Variable Valve Timing), VVL (Variable valve lift), etc., make the structure of modern engines more and more complex, and the design concept of integration and modularization is also more and more respected by the industry. On the other hand, people's requirements for car quality are not limited to the satisfaction of space and performance. Low noise and comfort have also become an important focus of car companies. At present, the above-mentioned complex technologies and structures are more and more integra...
