🔍 Key Concepts

• Basic construction and airflow path of a turbocharger on a marine diesel engine • Differences in how centrifugal, axial flow, rotary vane, and rotary screw compressors move and compress air • Typical design of high‑speed turbochargers used on diesel engines (impeller, volute, high RPM)

💭 Think About

• Picture the turbocharger cutaway: how does the compressor side look, and how does the air move from inlet to outlet? • Which of these compressor types is best suited to very high rotational speeds driven by exhaust gas turbines? • Think about which compressor types are more common in low‑pressure industrial blowers versus high‑speed engine turbochargers.

✅ Before You Answer

• Match the airflow direction (radial vs. axial) in a common diesel engine turbocharger to the correct compressor type • Recall that exhaust‑driven turbochargers generally use a single rotating wheel/impeller on the compressor side—identify which option fits that design • Eliminate compressor types more commonly used in positive‑displacement applications (steady volume per revolution) rather than dynamic, high‑speed turbochargers
