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.

In a 4-stroke cycle engine, two complete revolutions of the crankshaft are required to complete one cycle, which includes intake, compression, power, and exhaust strokes. Therefore, for each individual stroke (intake, compression, power, or exhaust), one rotation of the crankshaft corresponds to half of that duration. Thus, one stroke occurs for every 180 degrees of crankshaft rotation.
Two complete revolutions, therefore 720 degrees.
