The crankshaft completes two full rotations to complete one cycle of a four-stroke engine. In a four-stroke cycle, the engine goes through the intake, compression, power, and exhaust strokes, requiring two rotations of the crankshaft to complete this process. In contrast, a two-stroke engine completes one cycle with just one crankshaft rotation.

In a two-stroke cycle engine, the crankshaft completes one revolution to complete one thermodynamic cycle. This is because the two-stroke cycle combines both the intake and exhaust processes into a single crankshaft revolution, allowing for one power stroke for every crankshaft rotation. Thus, for each complete thermodynamic cycle, the crankshaft makes one full revolution.
In a four-stroke engine, one complete cycle consists of four strokes: intake, compression, power, and exhaust. This cycle requires two complete revolutions of the crankshaft, which equals 720 degrees of crankshaft rotation. Therefore, 720 degrees of crankshaft rotation are needed to complete the four-stroke cycle.
2 revolutions
The crankshaft makes two complete revolutions to complete one thermodynamic cycle. The crankshaft rotates 180 degrees during each stroke of the engine. Hence a total of two revolutions occur after completion of the four strokes. Chechout "www.howstuffworks.com " to see how crankshaft works.
It takes two revolutions of the crankshaft to complete the cycle of a 4-stroke cycle engine. Each revolution includes the intake, compression, power, and exhaust strokes of the engine.
The crankshaft does 2 full turns to make 1 cycle in a 4 cycle engine so, 4 is the answer.
In a 4-stroke engine, one complete engine cycle consists of four strokes: intake, compression, power, and exhaust. This cycle requires two full rotations of the crankshaft, which equals 720 degrees of crankshaft rotation. Each stroke corresponds to 180 degrees of crankshaft movement, collectively completing the cycle.
