🔍 Key Concepts

• heat rejection in diesel cycles and how often power strokes occur • differences in two-stroke vs four-stroke scavenging and exhaust processes • how double-acting or opposed-piston designs affect combustion and heat transfer

💭 Think About

• Think about which type of engine has the least time for heat to be carried away to cylinder walls and cooling systems before the exhaust stroke • Consider which design tends to have higher specific thermal loading (more power strokes per revolution or per cylinder volume) • Ask yourself how the different designs change the temperature of gases leaving the cylinder compared to how much cooling they receive inside the cylinder

✅ Before You Answer

• Compare how many power strokes per crankshaft revolution each engine type has • Consider which design has more surface area (pistons, cylinder walls, water jackets) to absorb heat from the gases before they exit • Verify which engine type is generally associated with higher specific exhaust temperatures in marine engineering texts or tables
