What is the purpose of an automotive filter?
1 Answers
Automotive filters are primarily used to remove impurities such as dust, metal particles, carbon deposits, and soot particles from engine oil, thereby protecting the engine. There are mainly two types: 1. The first type: Full-flow filter. It is connected in series between the oil pump and the main oil passage, filtering all the lubricating oil entering the main oil passage. 2. The second type: Bypass filter, which is connected in parallel with the main oil passage and only filters a portion of the lubricating oil pumped by the oil pump. The oil filter removes harmful impurities from the oil coming from the oil pan, supplying clean oil to moving parts such as the crankshaft, connecting rod, camshaft, turbocharger, and piston rings, providing lubrication, cooling, and cleaning functions, thereby extending the lifespan of these components. Simply put, the role of the oil filter is to filter the engine oil, making the oil entering the engine cleaner and preventing impurities from entering and damaging the precision components of the engine.
