Background
The filter is a filter that filters impurities or gas through filter paper. Generally referred to as an automobile filter, is an accessory of an engine.

The engine has three filters of air, engine oil and fuel oil, generally called three filters, and an air-conditioning filter, commonly called four filters.
In order to make the lubricating oil flow smoothly and prevent impurities from scratching and galling the surface of a part, the engine oil in the lubricating system must be strictly filtered before being sent to a friction surface.
