Focus on Car Maintenance: Do Not Neglect the Importance of Oil Filters

Technical characteristics of the oil filter on top of engine

Rubber seal: The seal of a high-quality oil filter is made of special rubber, ensuring zero oil leakage.

Anti-return valve: Only high-quality oil filters have this feature. When the engine is turned off, it prevents the oil filter from drying out. When the engine is restarted, it immediately produces pressure to supply oil for engine lubrication (also known as a check valve).

Filter paper: The requirements for the filter paper of the oil filter are higher than those of the air filter in the car. This is mainly because the temperature of the oil varies from 0 to 300℃, and the concentration of the oil changes with the sudden temperature changes, which affects the flow rate of the oil filtration.The filter paper of a high-quality oil filter should be able to filter impurities under extreme temperature changes while ensuring sufficient flow rate.

Overflow valve: Only high-quality oil filters have this feature. When the external temperature drops to a certain value, or when the oil filter exceeds its normal service life, the overflow valve will open under special pressure, allowing unfiltered oil to flow directly into the engine.Although impurities in the oil will enter the engine, the damage caused by this is much smaller than that caused by having no oil in the engine. Therefore, the overflow valve is key to protecting the engine in an emergency.

The engine is known as the "heart" of the car, and its importance is evident. Long-term work and careless maintenance can cause irreversible damage to the engine.

The small but important role of the oil filter on top of engine

In Filton oil filter supplier, During operation, the engine produces metal shavings, dust, carbon deposits, and gummy sediments. These substances gradually seep into the oil. The role of the oil filter is to filter out these mechanical impurities, maintain the cleanliness of the lubricating oil, and extend its service life.

Therefore, the oil filter must have strong filtering ability, low flow resistance, and long service life.

If the oil filter element is blocked, the oil cannot pass smoothly through the filter element, causing the filter element of the oil filter on top of engine to bulge or pass through the bypass valve.

This will cause the filter to fail, and the oil will still carry the worn debris back to the lubrication parts of the engine, causing the engine to wear more severely, and the working environment will become more severe.

The working environment of the oil filter is relatively harsh, not only should impurities in high-temperature oil be filtered out, but also a certain filtering accuracy must be ensured.

If only filtering accuracy is pursued, the filtering amount may be insufficient, resulting in insufficient lubrication of the engine. In mild cases, it may cause cylinder body tension, burn the crankshaft and bearing, while in severe cases, it may lead to engine cylinder pulling or explosion, affecting driving safety.

Selection techniques for the oil filter on top of engine

Appearance

The appearance is exquisite, the details are treated properly, and a good oil filter must use excellent manufacturing processes. The surface of the oil filter is smooth and shiny, and the printed graphics and fonts are clearly visible.

Handle it

The rubber ring has a soft texture but is not lacking in toughness. The seal is an important indicator of whether the oil filter on top of engine is good or bad. A good sealing ring will not have cracks at the fold after folding, and it will have sufficient elasticity when touched.

Shake it

The shell is firm and makes no sound when shaken firmly. The interior of the genuine brand oil filter is firm and makes no sound when shaken. The interior of an inferior oil filter is not firm and makes a noise when shaken.

Probe inside

If there is a check valve, it is located inside the oil port. Use a rod-shaped object such as chopsticks or a pen to probe into the oil port. The obstruction felt is the check valve made of rubber.

The engine is the heart of the car, and the oil filter on top of engine is the guardian of the engine. It can protect the engine from debris and impurities, and make the engine run better and longer.

Therefore, the oil filter is very important, and the oil filter on top of engine must be replaced on time to protect the engine.
