What is the function of a vehicle air filter?

[Patricia]

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.

After driving for several years, I've realized the air filter is quite crucial—it acts like a precise sieve, only allowing clean air into the engine for combustion. If not kept clean, dust clogs it up, leading to sluggish throttle response, slower acceleration, and increased fuel consumption. Once, after a trip to the countryside where I drove through dusty roads, the filter got dirty. After replacing it, the car felt noticeably more responsive. Maintaining it well helps prevent internal engine wear, saving money and hassle. Especially for frequent city commutes, it's best to check it during every maintenance service.

The primary function of an air filter is to remove impurities from the intake air, preventing dust particles from damaging internal engine components such as piston rings. I check it every time I change the oil and replace it if it's dirty, ensuring more complete combustion and reduced fuel consumption. Failure to replace it can lead to dust buildup, decreased performance, increased fuel consumption, and even engine failure. Simple maintenance can extend engine life and save money.
