🔍 Key Concepts

• Diesel engine firing pressure as an indicator of how much fuel/air is effectively burned in the cylinder • Relationship between exhaust temperature and how freely gases can leave through the exhaust system • Effect of a restricted exhaust manifold on gas flow, backpressure, and heat buildup

💭 Think About

• If the exhaust manifold is restricted, what happens to the flow of exhaust gases and the backpressure in the system? • How would increased backpressure affect how easily the engine can clear burned gases and take in a fresh air charge, and what does that do to firing pressure? • When hot gases are trapped longer in the exhaust side, what trend would you expect in exhaust temperature readings?

✅ Before You Answer

• Compare which choices show signs of heat buildup versus heat loss in the exhaust system • Ask whether a restriction would tend to make the engine work harder to push exhaust out, and if that would raise or lower firing pressure • Verify which combination (high/low) of firing pressure and exhaust temperature best represents a hotter, more choked exhaust path
