Embodiment Construction

[0021] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0022] Bolts are screwed through each bolt hole to fix the first bearing cap 1 to the cylinder head G, so that the lower surface 16 of the bearing cap is closely attached to the upper surface S of the cylinder head. When the engine is running, when the lubricating oil in the main oil passage 161 of the cylinder head reaches the oil storage tank 16, the lubricating oil in the oil storage tank supplies oil to the intake and exhaust camshaft bearings respectively through the oil passage 17 arranged on the lower surface 16 of the first bearing cover. , and enter the oil passage inside the hollow camshaft through the corresponding oil hole 171 on the camshaft T, and then lubricate each camshaft bearing.

[0023] In this embodiment, an oil pipe can be installed on the installation hole 8 of th...

Abstract

The invention relates to a first bearing cover of an engine cylinder cover, which is characterized in that: a bolt hole is arranged on the bearing cover, and is used for fixing the bearing cover onto the cylinder cover. An air inlet bearing and an exhaust bearing are connected with each other into a whole through a cross arm. At the same time, two oil holes which are arranged on the upper end of an air inlet cam shaft bearing are communicated with an oil passage of a variable valve timing (VVT) control valve through an external pipeline. An oil storage trough and the oil passage are cast on the lower surface of the first bearing cover, and the casting of the oil passage can greatly reduce the mechanical processing difficulty. The first bearing cover of the engine cylinder cover has simple design, is easy to arrange, is simple to process, and can effectively reduce the processing difficulty.

Description

technical field [0001] The invention relates to a first bearing cap, in particular to a first bearing cap applied to an engine cylinder head. Background technique [0002] In recent decades, many countries, engine manufacturers, and scientific research institutions have invested a lot of manpower and material resources in the research and development of new technologies based on the requirements of improving the power, economy and reducing pollution of automobile engines. The use of VVT satisfies the development of the current situation, but for engines with VVT, the oil circuit layout of the general engine cylinder head, especially the oil circuit layout of the first bearing cap is complicated, the processing procedures are cumbersome, and the processing is difficult. It is a big challenge for the processing technology. Contents of the invention [0003] The purpose of the present invention is to provide a first bearing cap of an engine, the bearing cap is suitable for t...
