2 revolutions
In a typical four-stroke engine, the crankshaft must complete two revolutions for the camshaft to complete one revolution. This is because the camshaft operates the engine's valves, which open and close once for every two complete cycles of the crankshaft (intake and exhaust strokes). Therefore, the ratio of crankshaft revolutions to camshaft revolutions is 2:1.
2 revolutions on the crankshaft

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.
crankshaft rpm (revolutions per minute)
The crankshaft does 2 full turns to make 1 cycle in a 4 cycle engine so, 4 is the answer.
2 full revolutions of the crankshaft equals one complete cycle on a standard 4 stroke internal combustion engine.
Two complete revolutions, therefore 720 degrees.

3000/60 or 50 revs per sec.
