Description

External oil filter

Technical Field

The invention relates to the technical field of engine oil filtering devices, in particular to an external engine oil filter.

Background

The oil filter, also called as oil grid, is used to remove dust, metal particles, carbon deposits and soot particles from oil and protect engine. The full-flow filter is connected in series between the oil pump and the main oil gallery, so that all lubricating oil entering the main oil gallery can be filtered. The shunting cleaner is connected with the main oil duct in parallel and only filters part of lubricating oil sent by the oil pump.

The existing oil filter is used for intercepting and filtering harmful impurities in engine oil by virtue of filter element holes, the smaller the micropores of the filter paper are, the better the filtering effect is, but the poorer the engine oil passing capacity is. The filter paper aims to solve the contradiction that the smallest particles of impurities can be filtered on the same filter paper micropore, and the engine oil which is supplied to an engine in a sufficient quantity can also pass through the micropore. The test of the international standard test method adopted by the filter efficiency ISO4548 of the oil filter by the filter division of the national internal combustion engine industry Association shows that: even the best oil filter in the market can only be designed to filter 60% of impurities in the engine oil, which is the maximum filtering value obtained after hundreds of experiments, in practical use, 40% of harmful impurities are also left and can not be effectively filtered by a paper filter element, in the 40% of impurities, because the ferromagnetic impurities are relatively fine and hard, the ferromagnetic impurities are more, the damage to the engine is the largest, in addition, because of the viscous characteristic of the engine oil, the engine oil throughput of different parts of the filter element is uneven, the part of the filter element is completely blocked by the impurities due to less engine oil throughput, the filtering effect of the part of the filter element is better due to less engine oil throughput, and if the oil throughput is not replaced in time, the defects that the oil output in the filtering process is not smooth or the impurities are extruded and the like are caused, and the service life of the engine is influenced.
