🔍 Key Concepts

• Relationship between engine load, firing pressure, and exhaust temperature in a diesel engine • Effects of injection timing (early vs. late) on peak pressure and exhaust temperature • How mechanical faults like leaking piston rings or combustion knock would show up in cylinder pressure and temperature readings

💭 Think About

• If all cylinder firing pressures are normal, what does that suggest about compression and combustion quality in each cylinder? • Which of the listed conditions would most likely affect exhaust temperature in the same direction on all cylinders, without lowering firing pressure? • For each choice, ask: would this make the engine work harder or less for the same speed, and how would that change exhaust temperature?

✅ Before You Answer

• Verify which conditions would reduce compression pressure and therefore tend to lower firing pressure as well as temperature. • Check which option is most likely to produce higher, not lower, exhaust temperatures – that option can be eliminated. • Confirm which situation matches: normal firing pressures across all cylinders + uniformly low exhaust temperatures.
