🔍 Key Concepts

• fuel injection timing and how it affects when combustion pressure peaks in the power stroke • the relationship between combustion completeness and exhaust temperature • symptoms of early vs. late fuel injection in a diesel engine (knock, power, exhaust heat, smoke)

💭 Think About

• When fuel is injected late, does peak pressure occur earlier or later in the power stroke, and how would that affect useful power output? • If combustion is still going on while the exhaust valve opens, what happens to the temperature of the exhaust gases? • Which option would you more likely associate with early injection (advanced timing): sharp pressure rise and knocking, or hotter exhaust leaving the cylinder?

✅ Before You Answer

• Match late injection specifically with what happens near the end of the power stroke and start of exhaust stroke. • Ask yourself which effect would logically reduce how much of the fuel’s energy is converted to work on the piston: is it more power, or wasted heat in the exhaust? • Separate in your mind: early injection is usually linked to one of the listed effects, while late injection is linked to another—identify which pair goes together.
