If the air filter is not replaced, the engine cannot run normally, and the car air filter may be blocked if the car air filter is not replaced. Replacing a clean air filter element can increase the efficiency of the engine by more than 10%. In summer, please check, clean and replace the air filter element to ensure the normal operation of the engine. Other effects of not replacing the air filter element on the car:
1. The engine needs to suck in a lot of air during the working process. If the air is not filtered, the dust suspended in the air is sucked into the cylinder, which will accelerate the wear of the piston group and the cylinder;
2. Larger particles enter between the piston and the cylinder, which will cause a serious "cylinder pulling" phenomenon, which is especially serious in a dry and sandy working environment;
3. The air filter is installed in front of the carburetor or the intake pipe, which plays the role of filtering out dust and sand in the air, and ensures that sufficient and clean air enters the cylinder.
4. If the air grid is not replaced for a long time, its filtering effect will decrease. The fine dust in the air will enter the combustion chamber of the engine through the intake pipe for combustion, causing serious wear of the engine cylinder;
5. The gasoline is not fully burned, and the carbon deposit on the throttle valve increases. Due to the increase in the carbon deposit inside the engine, the vehicle idle speed is unstable, the exhaust pipe emits black smoke, and the engine shakes abnormally.
6. Due to the adsorption of too many impurities on the surface of the air grid, it is easy to cause blockage and cause insufficient air intake of the engine. The car monitors the air entering the engine through the air temperature flowmeter, and the engine computer determines the fuel injection amount according to the air-fuel ratio! If the air grid is too dirty, it will also have a blocking effect on the air.
