Two
RPMs (Revolutions Per Minute) at the crankshaft.
Revolutions per minute of the crankshaft in the engine.
crankshaft rpm (revolutions per minute)
A crankshaft sensor senses the engine revolutions to basically tells the the car when 2 inject and ignite the fuel
2 revolutions on the crankshaft
It's usually measured in RPM - Revolutions-Per-Minute, counted at 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.
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.
They burn it in cylinders of internal combustion engine. Heat from burning pushes pistons, causing crankshaft to rotate. Rotation of crankshaft turns wheels.
Much more powerful, smoother power transfer to a rotating crankshaft and easier to control.
