Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing:

[0021] As shown in Figure 1 and Figure 2, the cylinder head is provided with a main oil passage 6 connected with the cylinder body. The main oil passage is the bolt hole of the cylinder head. In order to ensure a certain amount of oil in the oil passage, the bolt hole is The bolt hole diameter is 1-1.5mm larger.

[0022] The cylinder head is also provided with the first auxiliary oil passage 8 of the cylinder head and the vertical oil passage 10 of the cylinder head. Road 11 is connected with each other, and the direction of the oil passage is in turn the main oil passage 6, the first auxiliary oil passage 8 of the cylinder head, the oil passage 9 of the phase solenoid valve 3, the vertical oil passage 10 of the cylinder head, the auxiliary oil passage 11 of the bearing cap, the intake air passage Camshaft auxiliary oil passage 12, camshaft phaser 5, this oil passage is oi...

Abstract

The present invention relates to a lubricant passage way of VVT engine with a simple and compact structure, which can effectively reduce the weight of the engine. The technical proposal is that the lubricant passage way of VVT engine consists of a cylinder head, a phase electromagnetic valve, a cam shaft phasing device, an air inlet cam shaft, an air outlet cam shaft, a cam shaft bearing cover, a cam, a tapper arm and a valve. The present invention is characterized in that the cylinder head is provided with a main oil passage communicated with the cylinder and the main oil passage is the screw hole of the cylinder head.

Description

technical field [0001] The invention relates to a lubricating oil circuit of a VVT engine. Background technique [0002] With the development of the automobile industry, the requirements for the economy and power of the engine are getting higher and higher, so the requirements for the lubrication system of the engine are also getting higher and higher, so how to make the lubricating oil circuit simpler, the structure more compact, and the lubrication effect better? Better is the problem we need to break through. At present, the lubricating oil passage of the engine with VVT is basically to set the main oil passage in the middle of the front end of the cylinder head. The oil passage is outside the water jacket and must ensure a certain wall thickness, so the length of the cylinder head will be relatively increased by 10-15mm, and then There are two oil distribution passages above the oil pool of the cylinder head. The long oil passage is used to supply oil to the intake and ...
