🔍 Key Concepts

• Two-stroke vs. four-stroke diesel cycle and how many power strokes each produces per crankshaft revolution • Typical advantages of two-stroke diesels (power-to-weight, number of power strokes, torque characteristics) • Typical disadvantages of two-stroke diesels (thermal loading, scavenging, maintenance, temperature)

💭 Think About

• For each choice, ask yourself: is this usually considered an advantage or a disadvantage of two-stroke diesels compared to four-strokes? • Think about how often a two-stroke produces power compared to a four-stroke. What effect does that have on torque smoothness and on the engine’s temperature? • Which option would most likely be found in a textbook list of "problems" or "limits" of two-stroke marine diesels, especially regarding heat and gas exchange?

✅ Before You Answer

• Compare how many power strokes per crankshaft revolution each type has and decide if that makes torque more or less even • Recall whether two-stroke engines are usually lighter and more compact or heavier for the same power output • Consider whether having a power stroke every revolution affects cylinder temperatures and cooling demands compared with four-stroke engines
