Embodiment Construction

[0017] Below in conjunction with embodiment the present invention is described in further detail:

[0018] Such as figure 1 As shown, a V-type multi-cylinder diesel engine parallel symmetrical compensation lubrication system, in figure 1 The arrangement sequence of each component is clarified in , and the specific parameters and dimensions of each component need to be calculated and determined in combination with the characteristics of the diesel engine. The lubrication system of the present invention adopts a parallel compensation system of symmetrical double oil pumps and a parallel compensation system of symmetrical double main oil passages. , to meet the needs of V-type multi-cylinder diesel engines for larger oil flow, and reduce the design requirements of diesel engines for single parts. The parallel compensation system of the symmetrical dual oil pumps includes a symmetrical first oil pump and a second oil pump. The oil passage enters the first oil filter and the seco...

Abstract

The invention discloses a V-type multi-cylinder diesel engine parallel symmetrical compensation type lubrication system, the oil in the oil pan is pumped out by the oil pump, flows to the main oil passage, then flows through the oil passage of the diesel engine accessories, and finally flows back to the oil pan for lubrication system, the lubricating system adopts a parallel compensation system of symmetrical double oil pumps and a parallel compensation system of symmetrical double main oil passages. Part design requirements.

Description

technical field [0001] The invention relates to the arrangement of a V-type multi-cylinder diesel engine lubricating system, in particular to a V-type multi-cylinder diesel engine parallel symmetrical compensation type lubricating system. Background technique [0002] When the current V-type multi-cylinder diesel engine is designed for the layout of the lubrication system, the series arrangement is mostly adopted. It enters from one end of the engine (free end or flywheel end) and extends to the other end in turn. A pressure limiting valve is set at the end of the main oil passage. The existing technology can achieve diesel engine lubrication, but due to the tandem structure, the oil pressure of each cylinder is distributed in a decreasing manner, and the oil pressure difference between the oil inlet end and the end of the main oil passage is relatively large, which causes the oil to be delivered to the bearing bushes, bushings, etc. of each cylinder. There is a large differ...
