If the air filter is not cleaned for a long time, what effect will it have on the car? The following is a specific analysis:

1. Unbalanced fuel ratio. If the air filter is dirty, the fuel supply system incorrectly balances the air-fuel ratio, and the ECM (engine control module) adjusts the fuel mix ratio to compensate for the reduced intake. This leads to the wrong air-fuel ratio and therefore to inadequate combustion, reduced fuel efficiency, and reduced power.

2. Large amount of fuel. Pollution from the air filter will lead to poor carburetor atomization, resulting in increased fuel consumption, reduced ride reliability, and clogged catalytic converters (too much gasoline enters the engine, exceeding valve design values). The carbon buildup inside the valve limits the amount of air coming in, reducing vehicle performance and engine power, all due to air filter pollution!

Replace the air filter regularly, the service life of the vehicle will increase.
