Usually, people who use air filters have the following errors.
(1) Do not seek quality when purchasing
Since a small number of maintenance personnel did not recognize the importance of the air filter, it was only cheap, not quality, and was purchased at will, so that the engine was abnormally installed soon. Especially in the current market, there are many counterfeit and shoddy products, it is better to shop around, carefully purchase, and always adhere to the principle of quality first.
(2) Demolition at will in use
The engine must use an air filter, which is scientifically based. However, some drivers arbitrarily remove the air filter to allow the engine to directly draw into unfiltered air. Tests on the removal of air filters from trucks have shown that after removal of the air filter, engine cylinder wear will increase by a factor of eight, piston wear will increase by a factor of three, and piston ring wear will increase by a factor of nine.
(3) Maintenance and replacement are not based on actual conditions
In the air filter instruction manual, although the mileage or working hours are specified as data for maintenance or replacement. However, the maintenance and replacement cycle of the air filter is actually related to environmental factors. For vehicles that are frequently driven in dusty environments, the maintenance or replacement cycle of the air filter should be shorter; in an environment with less dust, the maintenance or replacement cycle of the air filter can be Prolonged appropriately. In actual work, many drivers do mechanically according to the regulations, and do not flexibly grasp according to different factors such as the environment, and must wait until the mileage is up to standard and the engine working condition is obviously abnormal. It should be noted that maintenance at this time will not only save the losses already caused, but will also cause greater harm. What's more, individual drivers simply don't know that the air filter will fail, and continue to use it as long as the outside is not damaged.
