🔍 Key Concepts

• Identify the flow paths on both sides of the central shaft (hot side vs. air side). • Notice the turbine wheel on one end and a compressor/impeller wheel on the other, mounted on the same shaft. • Compare this to what devices are used for crankcase protection, cooling-water circulation, and starting air on large diesel engines.

💭 Think About

• On a large marine diesel, which common device has an exhaust-gas side and a clean-air side connected by one shaft? • Does any crankcase safety device, cooling-water pump, or starting-air component normally have two separate scroll-shaped housings and rotating wheels on a common shaft like this? • What is the purpose of using exhaust-gas energy in an engine system – where is that recovered energy usually applied?

✅ Before You Answer

• Verify which choice involves exhaust gas energy driving a turbine connected to a compressor. • Confirm that crankcase explosion relief devices are usually valves or doors on the crankcase, not large shafted rotating machines. • Confirm that cooling-water pumps and air-start systems do not normally have a hot exhaust side with gas passages shaped like those labeled A in the illustration.
