🔍 Key Concepts

• Effects of early vs. late fuel injection timing on diesel engine performance • Relationship between firing pressure (peak cylinder pressure) and injection timing • How exhaust gas temperature changes when combustion happens too early or too late

💭 Think About

• Think about what happens inside the cylinder if the fuel is injected too early in relation to piston position at top dead center (TDC). Does pressure peak sooner or later? • If combustion starts earlier, how would that affect peak firing pressure and the temperature of the exhaust gases leaving the cylinder? • Compare which options show a combination of pressure and exhaust temperature that logically fits earlier, more complete combustion versus late, incomplete combustion.

✅ Before You Answer

• Identify which choice shows high vs. low firing (cylinder) pressure and decide which one matches early combustion near or before TDC. • Check which options show high vs. low exhaust temperature and recall whether early combustion usually leads to cooler or hotter exhaust. • Eliminate any answers that mainly describe loss of power and high fuel consumption, which are more typical of late injection or poor combustion efficiency.
