About air filter
A clean engine is highly imperative as it runs more effectively than a dirty one. It is no doubt that a car’s air filter is the engine’s first line of defense and aids by allowing clean air to the vehicle’s engine to get clean air. The air filters play a key role in the combustion process. It also helps in preventing airborne pollutants such as dirt, dust and leaves from getting pulled into the car’s engine and damaging it.
What is the purpose of air filter?
The air filters serve the essential purpose of preventing dust, dirt and other environmental pollutants from getting into the engine. As time passes, the air filter becomes dirty and jammed and will require a replacement.
How air filter works?
The engine inhales and expels a lot of air. So, the air filter performs the job of treating and refining the air passing through the air intake into the engine cylinders. The filter is made using porous materials and acts as a sieve to filter out the incoming particles and separating the air molecules from the impurities. The air molecules pass through while the crud remains caught in the filter membrane. In almost all the modern vehicles, the air filters are positioned in a large plastic box in the engine bay while in the carburetor engines, the air filter is a unit of the carburetor housing and is mounted right on the top of the carburetor.
Where is air filter located?
In almost all the modern vehicles, the air filters are located under the hood inside a rectangular cold air collector box that is found near the front of the engine compartment. A number of vehicles including the ones with carburetors have big round metal air cleaners.
