🔍 Key Concepts

• Compressor side of a turbocharger – know which end is compressor vs. turbine • Diffuser ring – stationary passage that slows the high‑velocity air leaving the impeller and raises its pressure • Relationship between impeller, diffuser, and volute (scroll) casing on the compressor side

💭 Think About

• First, identify on the drawing which end is handling exhaust gas and which end is handling intake/charge air. Which side is the compressor element? • Locate the compressor impeller on that side. Then ask: which labeled part immediately surrounds the impeller outlet and has passages for diffusing (slowing) the air before it enters the scroll? • Look at the stationary versus rotating parts around the compressor impeller. Which label is on the fixed ring of passages rather than on the rotating wheel or outer casing?

✅ Before You Answer

• Be sure the part you choose is on the compressor (air) side, not the turbine (exhaust) side • Confirm that the part is stationary, forming a ring of passages around the impeller outlet, not a rotating blade wheel • Verify it is located between the compressor impeller and the compressor scroll/volute casing, where velocity energy is converted to pressure
