Because a small number of maintenance personnel did not realize the importance of the air filter, they only wanted to buy cheap air filters without asking for quality, so that the engine appeared abnormal soon after installation.
Especially when there are many counterfeit and shoddy products in the current market, it is better to shop around, carefully choose the cabin filter in a car, and always adhere to the principle of quality first. Filton Filter is a leading car air filter supplier in China, for more custom selections of air filters, inquiry now.
The engine must use an air filter, which is scientifically based. However, some drivers remove the air filter at will, so that the engine can directly suck in unfiltered air to work.
The test of removing the air filter of the truck shows that after removing the air filter in the empty car, the wear of the engine cylinder will increase by 8 times, the wear of the piston will increase by 3 times, and the wear of the piston ring will increase by 9 times.
In the instruction manual of the air filter, although it is stipulated that the mileage or working hours are used as the data for maintenance or replacement. But in fact, the maintenance and replacement cycle of the air filter is also related to environmental factors.
For cars that often drive in an environment with a lot of dust, the maintenance or replacement cycle of the air filter should be shorter; for cars in an environment with less dust, the maintenance or replacement cycle of the air filter in the car can be extended appropriately.
In actual work, many drivers follow the regulations mechanically, instead of flexible control according to different factors such as the environment, insisting on waiting until the driving mileage reaches the standard and the engine working state is obviously abnormal before performing maintenance.
It should be noted that maintenance at this time will not only fail to recover the losses that have been caused, but will also cause greater harm. What's more, individual drivers don't even know that the air filter will fail, and continue to use it as long as the outside is not damaged.
The working condition of the air filter and when it needs to be maintained or replaced can be identified as follows:
In theory, the service life and maintenance interval of the air cabin filter in a car should be measured by the ratio of the gas flow rate flowing through the filter element to the gas flow required by the engine.
When the flow rate is greater than the flow rate, the filter works normally; when the flow rate is equal to the flow rate, the filter should be maintained; when the flow rate is lower than the flow rate, the filter can no longer be used, otherwise the engine's working condition will be worse It's getting worse and can't even work.
In actual work, when the filter element of the air filter is blocked by suspended particles to the extent that it cannot meet the air flow required for the engine to work, the engine's working state will appear abnormal.
When these symptoms appear, it can be judged that the air filter is clogged, and the air filter element in the car should be removed in time for maintenance or replacement. When maintaining the air filter element, attention should be paid to the color change of the inner and outer surfaces of the filter element.
After removing the dust, if the outer surface of the filter paper is clear and the inner surface is bright, the filter element can continue to be used; if the outer surface of the filter paper has lost its original color or the inner surface is dark, it must be replaced!
