What is the function of a vehicle air filter?

The function of a vehicle air filter is to filter the air entering the engine. The replacement method for the air filter is as follows: 1. Remove the damping rods on both sides of the glove box; 2. Take off the glove box to reveal a black rectangular cover plate, pry it open, and remove the clips; 3. Take out the old air filter; 4. Install the new filter element. The consequences of not replacing the air filter for a long time include: 1. Reduced filtration efficiency, leading to severe wear of the engine cylinders; 2. Incomplete combustion of gasoline, increased carbon deposits on the throttle, resulting in unstable idling, black smoke from the exhaust pipe, and abnormal engine vibration; 3. Blockage, causing insufficient air intake into the engine.
The air filter is a real hero in our cars, acting as the engine's respiratory system by filtering out dust, sand, and various small particles from the air. My old car has traveled many long distances, and once the filter gets dirty or clogged, the engine's air intake is restricted, combustion efficiency drops, fuel burns incompletely, and the car runs sluggishly while consuming more gas. If left unchanged for a long time, those impurities can wear down the pistons and cylinders, causing repair costs to skyrocket. I recommend checking it every 15,000 to 30,000 kilometers or about once a year—more frequently in dusty environments. DIY replacement isn’t hard either: pop the hood, remove the old one, and install the new one—usually done in ten minutes, saving money and giving peace of mind. Ensuring the engine breathes smoothly keeps the car powerful and extends its lifespan.
