What is the function of an air filter in an engine?

• A. To cool the engine components
• B. To trap dust and debris, ensuring clean air enters the combustion chamber
• C. To increase engine pressure
• D. To enhance fuel combustion

Answer: (B)

The function of an air filter in an engine is to trap dust and debris, ensuring that clean air enters the combustion chamber. This is crucial because the combustion process requires a precise mixture of air and fuel to operate efficiently. If dirt and particles enter the engine, they can cause wear and tear on internal components, lead to reduced performance, and negatively affect fuel efficiency. By filtering out impurities, the air filter plays a vital role in protecting the engine, promoting longevity, and maintaining optimal performance. Clean air is essential for the proper combustion of fuel, thereby also indirectly supporting the overall efficiency of the engine.
