Passenger Car Oil Filter Engine Oil Filter Synthetic Fiber High Efficiency Filtration

The engine oil filter in a passenger car is a core filtering component that ensures the normal operation of the engine. Its core function is to filter impurities, metal debris, carbon deposits, and other pollutants from the oil, preventing wear of precision components within the engine (such as pistons, crankshafts, and bearings), while maintaining the lubrication, cooling, and sealing properties of the oil. Its main features can be expanded from the dimensions of filtering performance, structural design, adaptability, and durability, as follows:

1. Core function: high-precision filtration, engine protection​

Filtration accuracy adapted to engine requirements:
Filtration accuracy is typically measured in microns (μm). Mainstream passenger car oil filters typically have a filtration accuracy of 10-30μm (some high-end filters can reach 5-10μm).
It effectively traps impurities in the oil, such as metal debris (such as iron and aluminum shavings) generated by engine wear, carbon particles from combustion, and airborne dust. If these impurities are not filtered out, they can scratch cylinder walls and wear bearings as the oil circulates, leading to reduced engine sealing, increased fuel consumption, and even cylinder scuffing.
It also preserves beneficial additives in the oil (such as anti-wear agents and antioxidants), preventing over-filtration from degrading oil performance.

2. Structural design: Adapting to engine layout, taking into account both sealing and easy maintenance​

Highly sealed structure prevents oil leaks:
The interface between the filter element and the engine is typically equipped with an oil-resistant rubber seal/gasket (mostly made of nitrile rubber or fluororubber). This seal is resistant to high temperatures (can withstand oil temperatures of 120-180°C) and oil corrosion, effectively preventing oil leakage from the interface during pressure circulation and ensuring full oil filtration.

3. Material characteristics: heat and oil resistant, ensuring long-term reliability​

Housing: Pressure-Resistant and Rust-Resistant Metal/High-Strength Plastic:
Traditional filter housings are mostly made of cold-rolled steel (galvanized or spray-coated). They offer strong pressure resistance (capable of withstanding 8-15 bar oil pressure, preventing breakage under high pressure) and are rust- and corrosion-resistant.
Some lightweight models utilize high-strength engineering plastic housings (such as PA66 + fiberglass), which are lighter (in line with overall vehicle lightweighting trends) while maintaining comparable pressure and temperature resistance.
