In a four-stroke engine, it takes 720 degrees of crankshaft rotation to complete one full engine cycle, as the cycle consists of four strokes: intake, compression, power, and exhaust. Each stroke corresponds to 180 degrees of rotation. In contrast, a two-stroke engine completes a cycle in just 360 degrees of crankshaft rotation, encompassing both the power and exhaust strokes in a single revolution.
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.
rotation of the crankshaft
The crankshaft converts the linear motion of the piston into rotation of the crankshaft.
In a two-stroke cycle engine, the crankshaft completes one full revolution to complete one thermodynamic cycle. This is because two strokes of the piston (one upward and one downward movement) correspond to one crankshaft revolution, allowing for both the intake and exhaust processes to occur within that single rotation.

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 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.
In a straight-six (I6) diesel engine, each cylinder fires once every two revolutions of the crankshaft. Since there are six cylinders, it takes a total of 720 degrees of crankshaft rotation (360 degrees for each complete revolution) to fire all cylinders. Therefore, all cylinders fire once in 720 degrees of crankshaft rotation.
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.
In a four-cylinder engine, a power stroke occurs once every two revolutions of the crankshaft. Since there are four cylinders, each cylinder completes a power stroke at intervals of 180 degrees of crankshaft rotation. Therefore, a power stroke is delivered every 90 degrees of crankshaft rotation when considering the firing order of the cylinders.
180 degrees per stroke.
90 degrees would be a half stroke.
It depends on the type of engine. In a four-stroke engine, there are four strokes - intake, compression, power (combustion), and exhaust - required to complete one full rotation of the crankshaft. In a two-stroke engine, there are two strokes - compression/ignition and exhaust - needed to complete one rotation.
Yes, if by "720 degrees of crankshaft rotation" you mean "two rotations" Here is a great animation of a four-stroke at work: http://www.animatedengines.com/otto.shtml
one rotation
In a four-stroke engine, the crankshaft completes two rotations to complete one full cycle of all four strokes: intake, compression, power, and exhaust. This means that each stroke of the engine corresponds to half a rotation of the crankshaft. Therefore, for each individual stroke, one full rotation of the crankshaft is required for two strokes.
