Problems solved by technology

Due to the reason of the external pipeline, this design is messy, and at the same time increases the risk of bump damage, bump damage is easy to cause oil leakage or leakage, resulting in damage to the oil circuit, the engine cannot work, resulting in the pressure release of the lubricating oil can not guarantee the engine. Lubrication, and the structural design of the external pipeline is not beautiful enough

Embodiment Construction

[0014] Most of the oil pans of existing engines are stamped parts of thin steel plates. This process cannot realize the design of the lubricating oil circuit inside the oil pan. Because it is a thin-walled part, the vibration noise is relatively large. The lubricating oil path of the existing engine is as follows: oil collector assembly → oil pump assembly → external pipeline → oil filter → cylinder auxiliary oil passage → main oil passage → inclined oil passage and cylinder head vertical oil passage .

[0015] The role of the oil collector assembly is to absorb oil from the oil pan and perform primary filtration. The role of the oil pump assembly is to absorb and pressurize the oil, and there is an internal oil circuit connected to the oil collector and the external pipeline. The function of the external connection pipeline is to realize that the oil from the oil pump assembly enters the oil filter. The function of the oil filter is to filter the oil, and the filtered oil en...

Abstract

The invention includes an engine oil collector, an engine oil pump, an engine oil filter, a cylinder, a cylinder head, an oil sump and a frame. A main oil passage, an auxiliary oil passage connected with the oil filter, an oblique oil passage and a vertical oil passage are disposed in the cylinder. An oil passage, an oil sump oil passage and a frame oil passage are disposed in the oil sump and the frame mechanism separately. The run of the basic oil passage is: the oil collector to the oil pump to the frame oil passage to the auxiliary oil passage to the oil filter to the main oil passage to the oblique passage to the vertical passage.

Description

technical field [0001] The invention relates to an automobile engine, more specifically to a lubricating oil passage of an automobile engine cylinder block assembly. Background technique [0002] Usually the oil pan of the engine is mostly stamped parts, because the stamping parts are thin-walled parts, and the stamping process cannot guarantee the formation of complex lubricating oil circuits inside the oil pan, so there is no lubricating oil circuit layout design inside the engine oil pan in the past , The disadvantage of the thin-wall stamped oil pan is that the whole machine is noisy after assembly, and it is easy to be bumped and deformed; in the past, the main bearing caps of the engine are mostly designed with several independent structures, that is, the four-cylinder engine has 5 independent main bearing caps, The disadvantage of the independent main bearing cap is that the overall rigidity of the main bearing cap is poor, which has an adverse effect on the noise of ...
