🔍 Key Concepts

• Exhaust manifold layout and how exhaust gas reaches the turbine (item 8 in the illustration). • Difference between pulse turbocharging and constant pressure turbocharging in terms of manifold volume and grouping of cylinders. • Visible features that would indicate 2‑stage turbocharging or boost‑controlled (wastegate/valve) arrangements.

💭 Think About

• Look closely at the exhaust pipes coming from the cylinders: do they enter a large common exhaust receiver, or do they remain in separate runners right up to the turbine inlet? • Ask yourself which options can be ruled out just by counting how many turbocharger stages are drawn and whether any control valves or wastegates are shown. • Consider how the design shown would help use the energy of individual exhaust pulses versus smoothing them into a more uniform pressure before the turbine. Which configuration matches that idea?

✅ Before You Answer

• Verify whether there is a large common exhaust receiver before the turbine, or only separate exhaust pipes feeding directly into the turbine housing. • Confirm that the illustration shows only one turbocharger stage (one turbine wheel and one compressor wheel). • Check if you can see any wastegate or boost-control valve in the exhaust or intake piping that would indicate boost-controlled turbocharging.
