What effect does the dirty air filter have on the car?

If the air filter of the car is too dirty, even using a throttle valve will not help. This will not only make the air filter easy to get dirty, but also lead to carbon deposition, which will eventually lead to safety hazards such as unstable idle speed and even flameout. Therefore, it is very important to keep the air filter clean and replaced. The main function of automobile air filter is to filter the air entering the engine and ensure that the intake air is too pure. Therefore, if the air filter element becomes dirty, it needs to be replaced in time. When the air filter becomes too dirty, a lot of dust will be deposited on it, which will hinder the circulation of air, thus reducing the air intake of the engine, further reducing the power of the engine and increasing fuel consumption. The air filtered by the air cleaner will be mixed with fuel to form combustible mixture, which will enter the cylinder for combustion. If there is no air filter in the air intake system, the air entering the cylinder may contain non-combustible impurities such as fine gravel and particles, which will cause wear and damage to the cylinder wall, piston, cooling ring and valve. Therefore, it is very important to keep the air filter clean and replaced.
