Problems solved by technology

[0005] 1. The oil pressure of the engine oil pressure feedback oil passage is taken from the inclined oil passage, the oil pressure is unstable, and the frequent adjustment of the oil supply by the oil pump will lead to frequent fluctuations in the oil pressure of the whole machine, poor lubrication of engine parts, and unstable VVT ​​operation. In addition, the oil pressure feedback oil passage is long, which will cause excessive oil pressure loss;
[0006] 2. The oil in the oil storage tank of the tensioner is taken from the inclined oil passage, which will cause the oil pressure at the first gear main bearing bush to be slowly established and low, and shorten the service life of the first gear main bearing bearing;
[0007] 3. The pressure feedback oil passage needs to be connected with the tensioner oil passage through machining, the oil passage is long, the processing technology is complicated, the layout space is not compact, and the processing cost is high

Abstract

The invention relates to an engine cylinder block lubricating oil path system which comprises a suction filter, an oil pump, an oil pump oil outlet pipe, an cross engine oil channel, an oil filter, an oil cooler, a vertical engine oil channel, main bearing oil channels, piston cooling nozzle oil channels, a main oil channel, a supercharger oil channel, an air inlet VVT oil channel, a tensioner oil storage pool oil channel, an exhaust VVT oil channel, a tensioner oil storage pool and an oil pressure feedback oil channel. The tensioner oil storage pool oil channel is connected with the main oil channel and the tensioner oil storage pool. The exhaust VVT oil channel is connected with the tensioner oil storage pool. The oil pressure feedback oil channel is connected with the tensioner oil storage pool and the oil pump. Oil of the oil pressure feedback oil channel is taken from the tensioner oil storage pool, the tensioner oil storage pool has the function of a pressure stabilization cavity, oil pressure is stable, and the overall engine lubricating effect and VVT work stability are improved.

Description

technical field [0001] The invention belongs to the field of engine lubrication, in particular to an engine cylinder lubricating oil circuit system. Background technique [0002] In order to cope with the national fuel consumption regulations and the energy crisis, more and more engines start to use variable displacement oil pumps to reduce the extra fuel consumption caused by the waste of oil pump flow. At the same time, in order to ensure the running performance of the engine, it is necessary to provide reliable lubrication for various parts of the engine, such as camshafts, crankshafts, bearing bushes, etc. The layout of the pressure feedback oil passage of the engine with a variable displacement oil pump will affect the oil pressure and stability of the VVT, bearing bush and other components, thereby affecting the performance of the whole machine. When the engine is working, the oil pressure of the whole machine should be reduced as much as possible fluctuation. The st...
