Clean air filter

The air filter is directly related to the air intake of the engine when the car is running. The manager of Guangben dealership told the reporter that the air filter will not be blocked when the car is only driving in the urban area, but if the car is driving on dusty roads, it is necessary to pay special attention to the cleanliness of the air filter.

If the air filter is blocked or there is too much dust, the air inlet of the engine will be blocked, and a large amount of dust will enter the cylinder, which will accelerate the carbon deposition speed of the cylinder, which will hinder the ignition of the engine and cause insufficient power, and the fuel consumption of the vehicle will naturally increase. If you are driving on a normal city road, you should check the air filter when the car is driving 5000 kilometers.

If there is too much dust on the filter element, consider blowing compressed air from the inside of the filter element to clean the dust. But the pressure of compressed air should not be too high to avoid damaging the filter paper. He told reporters that water or oil must not be used when cleaning the air filter to prevent oil and water from soaking the filter element.
