Which component removes solid contaminants from air entering the turbocharger?

• A. Air cleaner
• B. Oil cleaner
• C. Fuel filter
• D. Exhaust pipe and rain cap

Answer: (A)

The main idea is that the air entering a turbocharger must be clean, and the air cleaner is the component that achieves this by removing solid contaminants from the intake air. The filter media traps dust, dirt, and debris as air passes through, protecting the turbine wheel and bearings from abrasive wear and potential damage that could reduce boost and efficiency. A well-maintained air cleaner also helps maintain smooth airflow to the compressor, preventing performance issues. Oil cleaner, as the name implies, cleans lubrication oil, not the air entering the turbocharger. A fuel filter cleans fuel before it reaches the engine, which is unrelated to air intake filtration. An exhaust pipe and rain cap are part of the exhaust/induction path and do not filter incoming air for the turbocharger.
