🔍 Key Concepts

• Diesel engine combustion and exhaust temperature – what makes exhaust gas temperature go up or down • Engine load vs. temperature – how does reducing the load change exhaust temperature? • Effects of fuel quantity and timing on power, efficiency, and heat

💭 Think About

• Think about what happens to exhaust gas temperature when an engine is overloaded and working too hard. What operating change brings it back into a safe range fastest? • Which options would add more fuel or heat to the cylinders, and which would reduce the amount of heat energy being released? • How does changing fuel timing compare to simply changing how hard the engine is being worked?

✅ Before You Answer

• Identify which choice directly reduces the work or torque demand on the engine. • Eliminate any option that would increase fuel delivery or tend to increase cylinder pressure and temperature. • Consider which action is normally recommended in operating manuals when you see high exhaust gas temperature alarms.
