🔍 Key Concepts

• Identify which side of the turbocharger is the compressor (air) side and which is the turbine (exhaust) side in the illustration. • Recall the normal flow path: exhaust manifold → turbine → exhaust outlet and air filter/silencer → compressor → aftercooler → engine intake. • Notice that the part labeled B is on the same side as which wheel (air or exhaust) and whether it is an inlet or outlet for that flow.

💭 Think About

• Look at arrows K and G: do they show air or exhaust, and are they entering or leaving the wheel on that side? How does that relate to where B connects? • On the opposite side of the turbocharger, locate the exhaust gas inlet and outlet passages; does B resemble those exhaust passages, or does it look like an air discharge connection? • Ask yourself: once the air has been compressed by the compressor wheel, where must it go next in the engine’s intake system, and which fitting on the drawing looks designed for that connection?

✅ Before You Answer

• Confirm which side contains the compressor impeller (clean, intake air) and which side contains the turbine wheel (hot exhaust gas). • Verify whether point B is located upstream or downstream of the compressor wheel in the air path. • Match each answer choice to the correct point in the flow path (exhaust in, exhaust out, air in, air out to aftercooler).
