Q

For a given size engine, the two-stroke/cycle diesel engine will deliver more power than a four-stroke/cycle diesel engine because __________.

🔍 Key Concepts

• Two-stroke vs. four-stroke diesel cycle – how many power strokes per crankshaft revolution • Relationship between engine cycles, RPM, and power output • What happens in each stroke of a four-stroke vs. a two-stroke engine

💭 Think About

• Think about how many times in one complete cycle each engine type produces a power stroke. • At the same crankshaft speed (same RPM), which design allows more frequent power events in the cylinder? • Which option describes a fundamental cycle difference rather than something that might vary with specific design (like pressure or air flow)?

✅ Before You Answer

• Be clear on what a stroke is: one full movement of the piston from one end to the other. • Review the sequence of strokes in a four-stroke engine (intake, compression, power, exhaust) versus a two-stroke engine. • Check which choice directly refers to the number of power strokes per revolution rather than secondary effects like pressure or air quantity.
