Problems solved by technology

[0004] The increase of the inlet pressure of the oil pump can effectively reduce the power consumption of the oil pump. In this case, the oil pump can easily input the lubricating oil to the designated lubrication position by consuming less power. In order to increase the inlet pressure of the oil pump, there are currently Variable displacement oil pump, however, the structure of the variable displacement oil pump is very complicated, and also requires a complicated control structure. The purpose of reducing the power consumption of the oil pump is achieved by changing the gear width or changing the eccentricity of the rotor. The oil pump not only requires a large installation space, but also has a very high cost of installation and maintenance

Abstract

The invention relates to a machine oil sump strainer. The machine oil sump strainer comprises a lubricating oil channel and an oil inlet and an oil outlet respectively formed in two ends of the lubricating oil channel, and further comprises an oil return boost channel; one end of the oil return boost channel is communicated with the lubricating oil channel; and an oil return port for flowing in returned lubricating oil is formed in the other end of the oil return boost channel. In actual working process, the lubricating oil in the oil return boost channel is merged with the lubricating oil flowing in the lubricating oil channel by the oil inlet, so that the flow and the pressure of the machine oil sump strainer in the oil outlet are effectively increased; and the oil outlet of the machine oil sump strainer is communicated with an inlet of a machine oil pump, the machine oil sump strainer can effectively improve the inlet pressure of the machine oil pump, reduces the power consumption of the machine oil pump, and promotes the fuel economy. The invention further discloses a lubricating system using the machine oil sump strainer and an internal combustion engine with the lubricating system.

Description

Technical field [0001] The invention relates to the technical field of internal combustion engine production, in particular to an internal combustion engine, a lubrication system and an oil filter. Background technique [0002] As we all know, the internal combustion engine needs lubricating oil to lubricate each movement pair during operation to avoid dry friction of each movement pair, so as to ensure the reliable operation of the internal combustion engine. [0003] The oil pan, lubricating oil passage, oil pump and the oil filter set in front of the oil pump constitute the lubrication system of the internal combustion engine. With the gradual development of science and technology, the improvement of fuel economy and overall reliability has become the inevitable development of the internal combustion engine. Trend, reducing the power consumed by the oil pump is an important technical means to improve fuel economy. [0004] The increase in the inlet pressure of the oil pump can ef...
