🔍 Key Concepts

• Trace the air path from the turbocharger/blower to the scavenge air spaces and note exactly where part P is located. • Think about what devices are usually mounted in the air line just before the scavenge air receiver or air header on a two-stroke diesel engine. • Recall the different purposes of scavenge system components: compressors/blowers, non‑return (check) valves, coolers, and port/deflector shapes for turbulence.

💭 Think About

• Look closely at whether part P is in a rotating/moving assembly that could boost pressure, or if it appears to be a small fitting/flange in the air passage. • Ask yourself: does this part look like it changes air temperature, prevents backflow, or disturbs the flow pattern inside the cylinder? • Which option describes a function that must be provided right at the entrance to the air receiver/header to protect the blower/turbocharger and maintain proper flow direction?

✅ Before You Answer

• Confirm from the illustration that P is installed in the air line/wall leading into the scavenge air receiver or header, not in the cooler or turbocharger itself. • Check whether P appears to have a disc/plate and seat arrangement typical of a check (non‑return) valve, rather than fins or tubes for cooling or blades for boosting pressure. • Eliminate any choice that describes a function normally performed by the turbocharger/blower casing or by the scavenge port/deflector design, not by a small inline fitting like part P.
