🔍 Key Concepts

• compression pressure effect on combustion and temperature • how leaking valves or openings affect compression and exhaust heat • relationship between injection timing and exhaust temperature

💭 Think About

• Ask yourself: what happens to peak combustion temperature and exhaust temperature when compression is reduced but fuel is still injected? • Which of these faults would physically let pressure escape from the cylinder during compression or power stroke? • Which option would most likely LOWER exhaust temperature instead of raising it?

✅ Before You Answer

• Identify which choice directly causes loss of compression inside the cylinder. • Decide which fault would cause hot gases to leak past a boundary, heating something they shouldn’t. • Eliminate any choices that normally produce cooler, not hotter, exhaust gases.
