The vehicle engine can be said to be a very precise part, which is often damaged by a small impurity. The air filter is an important spare part to ensure that the air entering the engine is clean.

Equivalent to the human nose, it is the first "level" for air to enter the engine. Its function is to finely filter the air entering the engine cylinder, filter out the sand and some suspended particles in the air, so that the air entering the engine is relatively pure, so its maintenance I will take stock of the air filter here. The maintenance method of the device is hoped to be helpful to the majority of car owners.

Clean the empty filter regularly.

If the air filter is the "nose" of the car, then the adjustment of the air filter is directly related to whether the nose of the passengers in the car can breathe healthy air.

Filter the air entering the car from outside the car, improve the cleanliness of the air, and ensure the health of the passengers in the car. Keeping the air filter clean is very important if the vehicle travels frequently on dusty roads. In the colder temperature in winter, some car owners will close the windows when driving, only open the internal circulation, and do not open the empty switch. The master pointed out that this is incorrect. Driving for a long time will cause the air in the car to be turbid, which will bring certain hidden dangers to human health.

Under normal circumstances, the filter needs to be replaced once when the vehicle is running at 8000 km ~ 10000 km empty. Usually only regular cleaning is required between seasons, especially after winter. The empty filter can also be cleaned by itself, it is not difficult.

How to maintain the air filter?

According to the maintenance cycle of the vehicle, under normal road conditions, the air filter should be cleaned and maintained every 5,000 kilometers. In areas with heavy sand and dust and poor air quality in the surrounding environment, the maintenance interval mileage should also be shortened accordingly. The master recommends cleaning once 3,000 kilometers in advance. When the car travels 20,000 kilometers, the generally empty air filter needs to be replaced.

Cleaning DIY Air Filters

Tool: Screwdriver

1. Shut off the engine and stop. Make sure the vehicle is off and cool down for 15-20 minutes, then open the hood to find the location of the air filter. The air filter is generally located on the right side of the engine compartment, you can check the location marking in the vehicle manual.

2. Hold the filter element. Open the lock of the filter cover, remove the nut fixing the cover, pull down the baffle, and take out the filter element. When removing the filter element, take care to prevent impurities from falling into the carburetor.

3. Clean the filter element. Check for more dust in the filter element. Tap the end face of the filter element lightly, and use compressed air to blow off the dust on the filter element from the inside out. If there is no compressed air, tap the filter element lightly with the handle of a screwdriver, then use a brush to clean the outside dirt. Do not wash with gasoline or water.

If the air filter is severely clogged, it needs to be replaced with a new one.

4. After cleaning the filter element, install all parts in the reverse order of removal.

2 How often should the air filter be replaced?
The air filter has a great impact on the air environment of the car, so when using the car, you must always pay attention to the air quality of the car and replace the air filter frequently. So, how often should the air filter be replaced?

1. [/k0/]The working principle of the air filter

During the working process of the engine, a large amount of air is sucked in. If the air body is not filtered, the dust suspended in the air body will be sucked into the cylinder, which will accelerate the wear of the piston group and the cylinder. Large particles entering between the piston and cylinder can cause severe cylinder pulling, especially in dry and sandy working environments. The air filter is installed in front of the carburetor or intake pipe to filter out the dust and sand in the air to ensure sufficient and clean air to enter the cylinder.

2. How often should the air filter be replaced?

Engine air filter, recommended replacement interval: once every 15,000 kilometers. If the road surface is particularly dusty, we can shorten the replacement cycle of the air filter to 10,000 kilometers.

3. Maintenance and repair of air filter:

1. Clean the filter yourself, open the front cover, there will be a black square or rectangular box. Then there's a big exhaust pipe that goes to the throttle. There are some screws and some buckles on it. Easy to open and take out. Generally, if you wash it, just blow off the dust. If it is too dark or has been used for a long time, it is recommended to replace it. During installation, it is also necessary to clean the air and blow it into the room first.

2. Regularly clean the air filter or replace the filter element. A car engine is a very delicate part, and the smallest impurities can damage the engine. Therefore, the air must be carefully filtered by an air filter before entering the cylinder. The air filter is the patron saint of the engine. The condition of the air filter is related to the life of the engine. If a dirty air filter is used during driving, it will lead to insufficient engine air intake, incomplete fuel combustion, unstable engine operation, reduced power and increased fuel consumption. Therefore, the car must keep the air filter clean.

3. Under normal road conditions, when the car travels 7500-8000 kilometers, the air filter must be cleaned and maintained. Maintenance intervals should be shortened accordingly in areas with high sand and dust content. Dry air filters are widely used in new cars. The dry air filter element adopts resin-treated microporous filter paper, which has the characteristics of good filtering effect and convenient maintenance. Due to different models, their structures and shapes are also different, but the maintenance methods are basically the same. When servicing, follow the mileage specified by the car manufacturer. How often should the above air filters be replaced? Hope it helps you!
