🔍 Key Concepts

• Diesel combustion timing in relation to top dead center (TDC) • What happens if combustion pressure peaks before vs. after TDC • Effects of cylinder pressure on piston movement and power output

💭 Think About

• Think about where the piston is and what it is doing if fuel is injected too early in the compression stroke. • Ask yourself: when does combustion provide the most useful work on the piston—while it is still moving up, or just after it starts moving down? • Consider which choice describes a situation where pressure is building at the wrong time, so less of that pressure is converted into useful work.

✅ Before You Answer

• Verify which option describes pressure/expansion peaking during compression instead of the power stroke. • Eliminate any choice that talks about ignition being delayed, because early injection is about events happening too soon, not too late. • Check which option matches the idea that combustion force is acting against the piston rather than pushing it down for maximum power.
