Question 1 of 27070

In diesel engines, the four basic events (intake, compression, power and exhaust) are performed once in __________.

🔍 Key Concepts

• Four-stroke vs two-stroke cycles – how many piston strokes and crankshaft revolutions are in each • In a two-stroke diesel, how often does you get a power stroke compared to crankshaft turns? • Relationship between piston stroke, power stroke, and crankshaft revolution

💭 Think About

• Visualize one full operating cycle in a two-stroke diesel: when does intake, compression, power, and exhaust occur relative to the piston’s up and down motion? • Compare that to a four-stroke engine: how many piston strokes and crankshaft turns are required to complete the same four events there? • Ask yourself: in a two-stroke engine, how many times does the piston move (up or down) before all four basic events have occurred once?

✅ Before You Answer

• Be clear on what a stroke is: one full movement of the piston either up or down • Remember that one crankshaft revolution equals two piston strokes in a typical reciprocating engine • Check which options incorrectly mix up power strokes with total strokes needed to complete all four events
