🔍 Key Concepts

• This is a cross‑section of a turbocharger showing a turbine on one side and a compressor on the other • Area A is the compressor impeller/housing that boosts intake air pressure • The shaft in the middle connects the turbine wheel on one end to the compressor impeller at A

💭 Think About

• Trace the flow of exhaust gas through the housing: which side of the unit do the exhaust gases enter and what do they turn? • Ask yourself: does the impeller at A get its energy directly from a fluid acting on its blades, or from the shaft that is turned by another fluid? • Look at where the air path is versus the exhaust path in the illustration; which fluid is actually doing the work that spins the common shaft?

✅ Before You Answer

• Identify which side of the drawing carries exhaust gas and which side carries intake air • Confirm that the impeller at A is rigidly mounted on the same shaft as the turbine wheel on the opposite end • Make sure you distinguish between the working fluid that powers the shaft and the fluid being compressed by the impeller at A
