Question 4004

What is the air filter for?

  1. To clean the air for the heater.
  2. To clean the air that cools the engine.
  3. To clean the air that mixes with the fuel.
Show answer and explanation

Correct answer: To clean the air that mixes with the fuel.

The air filter traps dust and impurities in the air entering the engine, where it mixes with fuel and burns. Without it, that dust would wear down the parts. It does not clean the air that cools the engine or the air for the heater. In the image, the filter is visible in its open housing next to the engine.
