Question

The purpose of the air filter is to:

A) Circulate clean air within the cabin of the car
B) Keep foreign material out of the fuel system
C) Remove toxins from exhaust before it's emitted
D) Use air to cool down the engine

Answer 1

The correct answer is option B) Keep foreign material out of the fuel system.

Step-by-step explanation:

The purpose of the air filter in a vehicle is to keep foreign material out of the fuel system. This is critical because it ensures that only clean air enters the engine's combustion chamber, preventing damage and maintaining engine efficiency.

Changing filters regularly is essential for maintaining good air quality and protecting engine components from debris like dust, pollen, and other pollutants. The air filter is not designed to circulate air within the cabin, remove toxins from exhaust, or specifically cool down the engine, though it does help with overall vehicle operation and efficiency.
