The oil filter is one of the core components of the engine lubrication system. Its functions and advantages are as follows:
1. Function of the Oil Filter
1. Filtration of Impurities
- Intercept impurities in the oil, such as metal debris (e.g., worn piston rings, bearing fragments), dust, combustion residues (carbon deposits), and gummy substances produced by oxidation, preventing them from entering the engine interior.
- Avoid the friction between impurities and metal surfaces, reducing engine wear.
2. Protecting Precision Components
- Ensure the cleanliness of the engine oil and protect the sliding surfaces of key components such as the crankshaft, camshaft, and cam follower, thereby extending the lifespan of the engine.
3. Maintain the performance of the engine oil
- Remove water, oxidation by-products and sludge from the engine oil to maintain its lubrication, cooling and sealing properties.
- Prevent sludge from blocking the oil channels or oil holes to ensure smooth circulation of the engine oil.
4. Collaborate with engine oil
- Work in conjunction with the engine oil to form a "cleaning - filtering" cycle, continuously providing a clean lubrication environment for the engine.
2. Advantages of the Oil Filter
1. Extended Engine Lifespan
- Reduces direct friction between metals, minimizes internal engine wear, and prevents severe faults such as early cylinder seizure and bearing burnout.
2. Enhance lubrication efficiency
- Maintain the cleanliness of the engine oil to ensure its lubrication performance, reduce friction resistance, and increase the engine's power output efficiency.
3. Reduce maintenance costs
- Prevent engine damage caused by pollution, reduce the probability of major repairs, and save maintenance expenses over the long term.
4. Environmental Protection and Emission Reduction
- Reduce carbon deposits inside the engine and pollutant emissions, thereby indirectly lowering the content of harmful substances in exhaust gases.
5. Extend the lifespan of the engine oil
- Filtering out impurities can slow down the oxidation and deterioration of the oil, allowing it to maintain its performance for a longer period of time (this requires regular oil changes).
6. Economy
- Although it needs to be replaced regularly, compared to the repair cost for engine damage, the cost of filter replacement is extremely low and offers high value for money.
