🔍 Key Concepts

• Trace the airflow path from the turbocharger compressor to the engine cylinders • Understand what a charge air cooler (aftercooler) does in a turbocharged diesel • Recognize the difference between intake/charge air components and exhaust system components

💭 Think About

• Follow the white arrows: after the air leaves the compressor wheel, which major component does it enter before reaching the intake valves? • Look at the shape of part 3 and the gauges on its side—what kind of function usually requires a box-like housing and temperature/pressure monitoring? • Compare where part 3 is located relative to the exhaust piping (dark arrows). Does part 3 handle hot exhaust gas or compressed intake air?

✅ Before You Answer

• Confirm whether component 3 is on the intake (white arrows) or exhaust (dark arrows) side of the system • Decide if the function of 3 is to cool and distribute compressed intake air or to collect and discharge exhaust gas • Ask yourself which option name best matches an air‑side, box-like, cooled component rather than a simple pipe or muffler
