🔍 Key Concepts

• Two-stroke vs. four-stroke diesel cycles – how many crank revolutions per power stroke and what the strokes are used for • Starting air work load – what the starting air actually has to overcome when cranking an engine (compression, friction, pumping losses) • Intake and exhaust strokes – when they occur in each type of engine and how they affect resistance while cranking

💭 Think About

• Think about which strokes in a four-stroke engine do NOT produce power but still require energy to move the piston and pump air through the engine. • Consider how many separate strokes in each engine type involve compressing or moving air without getting any power back immediately. • Ask yourself: during engine starting, what is the starting air physically doing inside the cylinders of a two-stroke vs a four-stroke engine?

✅ Before You Answer

• Be clear on the basic sequence of strokes for four-stroke (intake–compression–power–exhaust) versus two-stroke (power and compression combined with scavenging). • Verify which option mentions something that would directly reduce the amount of work the starting air must do, rather than a general engine characteristic. • Eliminate any choice that suggests something unrealistic, like no internal friction, since all real diesel engines have friction and pumping losses.
