Explanation:

Air cleaner / Filter:

  • Air filter is used in the intake manifold of an engine.

  • Uncleaned air will cause faster wear and damage to the engine parts, so air is filtered before entering inside the cylinder bore using an air cleaner.
  • The intake manifold is connected with the air cleaner and cylinder head intake port of the cylinder head.
  • It allows the fresh air to flow from the air cleaner to the cylinder through the inlet valve.
  • The intake manifold is made of cast iron or aluminum.

  • It reduces the noise of the intake air.
  • It acts as a flame arrester during an engine backfire.
