🔍 Key Concepts

• Turbocharged diesel engines: relationship between engine load, exhaust gas energy, and turbocharger speed • How constant engine RPM with changing load affects air and fuel demand • Role of the turbocharger in maintaining air supply and scavenging as power demand changes

💭 Think About

• When the engine speed stays the same but the load increases, what happens to fuel injected and exhaust gas energy? How would that affect the turbocharger? • Think about whether the turbocharger is directly governed by the engine speed, or by the exhaust gas flow and temperature. • If the load on the engine decreases at constant RPM, what happens to the amount of air and fuel needed, and what does that imply for turbocharger speed?

✅ Before You Answer

• Verify whether turbocharger speed depends more on exhaust gas conditions than on crankshaft RPM. • Check how increasing load at constant RPM changes: fuel rate → exhaust temperature/volume → turbine power. • Eliminate any option that implies the turbocharger speed is completely independent of load changes at constant engine speed.
