Question 1 of 27070

Q

At rated engine load and RPM, the diesel engine turbocharger is powered by __________.

🔍 Key Concepts

• How a turbocharger works on a diesel engine • Source of energy that spins the turbocharger turbine at normal operating load • Difference between mechanical drive and gas flow drive systems

💭 Think About

• Think about what part of the engine produces a strong, continuous flow of energy at rated load that can spin a turbine at very high speed. • Consider which option would still be available and increasing in energy as engine power and RPM increase. • Ask yourself: on most marine diesels, is the turbo physically driven by a shaft, belt, or clutch from the crankshaft, or is it driven by something flowing through it?

✅ Before You Answer

• Identify which choices are mechanical drives from the crankshaft and which rely on fluid or external power. • Remember that a turbocharger and a supercharger are not driven the same way on typical marine diesels. • Eliminate any option that would add significant parasitic load directly to the crankshaft at high RPM.
