🔍 Key Concepts

• Study the airflow path in the illustration: intake → compressor → intercooler → engine → exhaust → turbine. • Remember a turbocharger’s compressor and turbine are on the same shaft, but that shaft is not mechanically geared to the crankshaft. • Think about how engine load affects exhaust gas energy, and how that would influence turbine/compressor speed.

💭 Think About

• From the drawing, where exactly does the compression of the intake air take place? Is it in the cleaner or another component? • Is the turbo shaft speed required to be the same as engine RPM, or can it change independently as exhaust flow changes? • When the engine takes more load at the same RPM (e.g., pushing harder against the prop), what happens to fuel rate, exhaust flow, and thus turbo speed and power?"

✅ Before You Answer

• Confirm which component in the figure is actually labeled compressor and where the air cleaner is located relative to it. • Decide whether the turbo shaft speed is fixed to engine RPM or governed by exhaust gas flow and engine load. • Ask whether compressor power use would depend only on engine speed or more directly on how hard the engine is working (load/exhaust energy).
