🔍 Key Concepts

• Location and function of the exhaust manifold in a turbocharged diesel diagram • Where an air filter and aftercooler are normally placed in the air path relative to the turbocharger • Purpose and usual location of a non-return scavenge valve on a 2-stroke diesel engine

💭 Think About

• Look at where item R is drawn relative to the piston, liner, and crankcase – is it on the air-intake side, exhaust side, or between scavenge space and crankcase? • Trace the airflow from atmosphere through turbocharger to the cylinder and decide at what point each listed component would logically appear. • Ask yourself which of these components must act as a one‑way device connected to the scavenge air space to protect the crankcase.

✅ Before You Answer

• Verify whether item R is connected to the exhaust gas outlet at the top (if so, that supports one specific option). • Check if R is on the clean air side before or after compression and cooling – that would match the air filter or aftercooler possibilities. • Confirm if R is drawn as a small valve on the side of the scavenging space/crankcase interface, which would match a one-way (non-return) valve function.
