A piston in a four-stroke/cycle diesel engine makes four strokes during each __________.

Question 1 of 27070

A piston in a four-stroke/cycle diesel engine makes four strokes during each __________.

🔍 Key Concepts

• four-stroke diesel cycle (intake, compression, power, exhaust) • relationship between piston strokes and crankshaft revolutions • meaning of a mechanical cycle of operation in an engine

💭 Think About

• Count how many up-and-down piston movements happen from the start of intake back to the next time intake starts again • Ask yourself: does one complete four-stroke cycle take one crankshaft revolution or two? • Decide whether the question is asking about a full engine cycle or something longer (like two cycles)

✅ Before You Answer

• Be sure you know that a stroke is one full travel of the piston in one direction (up OR down) • Confirm how many crankshaft revolutions are required for all four strokes to occur in a four-stroke engine • Match the time in which four strokes occur with the choice that describes one complete engine cycle, not multiple cycles
