Why it is more powerful after exchanging the air filter?

The air filter element is so dirty that it affects the intake air volume of the engine. As a result, the intake air volume of the engine is less when the same accelerator is activated, and the fuel injection volume is also reduced, and the natural power is reduced. After the air filter is replaced, the air absorption becomes more efficient, and the same throttle is activated, more fuel can be injected, so the power becomes better, and the throttle becomes more sensitive.

Three elements of automobile work: good gas mixture, suitable compression ratio, and strong spark. The gas mixture is actually the matching of air and fuel in a certain proportion. The technical term is called air-fuel ratio. Its best state is 14.7:1, that is, 14.7 grams of air is needed for every 1 gram of gasoline burned. From here, we know that if the power is to go up, more air must be entered into the cylinder to burn the fuel. The air distribution system is actually very complicated. In order to ensure that the air entering the engine is free of impurities and foreign matter, an air filter element is required for filtration. Therefore, it is no exaggeration to say that the air filter is the gatekeeper of the valve train.

The function of the air filter is to filter the impurities used in the air into the cylinder, but there must be enough flow to do so. The poor air permeability of the air filter will directly affect the power of the car. You should check the air filter when you change the oil for car maintenance. Also, it has a lot to do with the road conditions. Don’t underestimate the role of the air filter. If it is not replaced in time, it will have a great impact on the life of the engine.
