Automatic machine oil cleaning system, oil return pipeline of communicating vessel, and engine system

Abstract

The embodiment of the invention provides an automatic machine oil cleaning system, relates to the technical field of internal combustion engines lubrication, and is used for prolonging the replacing period of machine oil in an engine, reducing the cost of a machine oil cleaning system, and improving the reliability of the machine oil cleaning system. The automatic machine oil cleaning system comprises an auxiliary machine oil box, an oil supply device connected with the auxiliary machine oil box and the engine respectively, and an oil return pipeline of a communicating vessel, wherein two ends of the oil return pipeline are communicated with the bottom end of an oil pan and the top end of the auxiliary machine oil box respectively; the peak of the oil return pipeline is higher than the set machine oil level of the oil pan; the set machine oil level of the oil pan is lower than the accessible uppermost level and the accessible bottommost level of the engine; the height difference between the set machine oil level of the oil pan and the accessible uppermost level or the accessible bottommost level is set according to the pressure in the oil pan during the operation of the engine and the atmospheric pressure, so that when the machine oil level in the oil pan is higher than the set machine oil level, machine oil can flow back to the auxiliary machine oil box along the oil return pipeline.

Description

technical field [0001] The invention relates to the technical field of internal combustion engine lubrication, in particular to an automatic engine oil cleaning system, an oil return pipeline of a connector thereof and an engine system. Background technique [0002] Engine oil, that is, engine lubricating oil, can lubricate, clean, cool, seal, and reduce wear on the engine. The engine oil will consume a certain amount during the operation of the engine, and metal wear debris, dust, carbon deposits and colloidal deposits oxidized at high temperature, water, etc. in the engine will continue to be mixed into the engine oil, so the engine needs regular maintenance , replace the engine oil, clean or replace the oil filter, how to extend the maintenance interval of the engine oil, and reduce maintenance costs have always been a major issue to be solved urgently in the relevant industries. [0003] In order to extend the service life of the engine oil, the existing engine oil auto...
