Question 1 of 27070

Which of the following devices will increase the power output of a diesel engine without increasing its frictional load?

🔍 Key Concepts

• Engine frictional load vs. power output • Difference between mechanically driven and exhaust-gas driven supercharging devices • How blowers/superchargers are powered on diesel engines

💭 Think About

• Which devices are driven directly from the crankshaft or gear train, and which are powered by something else? • If a blower is driven mechanically by the engine, what happens to frictional and mechanical load on the engine? • Which device can use otherwise wasted energy (like exhaust gas) instead of adding load to the rotating parts of the engine?

✅ Before You Answer

• Identify which option uses exhaust gas energy rather than crankshaft power • Confirm which blowers are gear/shaft driven and therefore add to mechanical load • Eliminate any devices that clearly require additional shaft power from the engine to operate
