The sudden epidemic in 2020 has taught us the importance of masks. For heavy trucks, the air filter is like a mask, filtering out dust and impurities in the air and giving the engine a good operating environment.
People's masks need to be replaced every day, and of course the "masks" of the car also need to be maintained regularly.
Today, the editor will talk to you about the common sense of truck air filter maintenance and take you out of the misunderstanding of air filter maintenance.
Myth 1
The air filter element does not need to be cleaned and replaced, and can be used for a long time.
correct
This will reduce the intake air volume, reduce the engine power, and increase the internal wear of the engine. The main filter element in the air filter is the filter element. If it is not cleaned or replaced for a long time, a large amount of dust inside the air filter will accumulate. Once the air filter is completely blocked, it will greatly increase the air intake resistance, reduce the intake air volume, and cause fuel combustion. Incomplete, resulting in decreased engine power and poor economic performance.
If the filter element is used for a long time beyond the service life of the filter element, the filter element may be damaged and the filtering function will be lost. A large amount of dust will enter the cylinder, causing accelerated wear of important parts, and the dust will also enter the oil pan through the piston ring gap, which will bring bad consequences to the lubrication system.
If it does not work with an air filter, the wear of the piston and cylinder liner increases by 3-5 times, and the wear of the piston ring increases by 8-10 times. Therefore, it is of great significance to maintain and maintain the air filter strictly in accordance with the technical requirements.
Myth 2
There is no life limit for the cleaning and replacement of the air filter element. If it is dirty, replace it or wait for it to be blocked.
correct
The air filter element has a certain design life limit, when the service life is exceeded, the function will decline. Each model's manual has recommended filter maintenance, replacement mileage or time.
Under normal circumstances, it is recommended that you: clean the filter element every 8,000 kilometers or half a year, and replace the filter element every 30,000 kilometers. If it is used in harsh environments for a long time, the maintenance and replacement cycle should be shortened appropriately.
Myth 3
The replacement of the air filter element does not need to use the original parts, as long as it can be installed in it, it can be used normally.
correct
The air filter element is designed and matched according to the performance of the engine and the size of the air filter housing. Different materials and sizes will affect the filtration performance and air intake resistance of the air filter. Replacing a filter element whose size or filter material is inconsistent with the original one may reduce the filtration efficiency of the air filter or increase/reduce the intake resistance of the engine. Although you will not immediately perceive a bad driving experience, over time, it will make your love The car was damaged.
Some OEM models use a neural network structure, and the use of non-original filter elements may affect the accurate judgment of the engine air intake and control system, and directly cause the engine fault indicator to light up.
Therefore, when the air filter element is repaired and maintained, be sure to use the original filter element spare parts in strict accordance with the technical requirements, and do not buy the filter element from informal channels for petty cheap.
