how is the angle between power strokes determine
It depends on the type of engine that is being operated. For example, consider a four stroke engine. It contains suction, inlet, power stroke and exhaust strokes. So that means the crank has to travel about 720 degrees to reach the same initial position. So if we consider the power stroke at the starting position then it will take the same 720 degrees to the same powerstroke position. But if we construct a stroke engine then it will take only 360 degrees to computer full cycle of 2 strokes. Then it will only take 360 degrees to reach the same power stroke if we consider it as the initial position.
Where as if we consider more than 1 cylinder then the power stroke angle will be defined by dividing the power stroke angle with the number of cylinders. That means if we consider a four stroke four cylinder engine then the power stroke angle will be 720 / 4. In this way the power stroke angle will be calculated.
