Do 2 strokes have more power than 4 strokes?
Typically, a 2-stroke engine creates more torque at a higher RPM, while a 4-stroke engine creates a higher torque at a lower RPM. That being said, 2-stroke engines are more powerful. Two-stroke engines are a much simpler design, making them easier to fix. They do not have valves, but rather ports.
How do you calculate the number of strokes?
Engine displacement is calculated by multiplying the cross-section area of the cylinder (determined by the bore) by the stroke length. This number is multiplied by the number of cylinders in the engine, to determine the total displacement.
How many power strokes does a 4 stroke engine have?
A four stroke engine delivers one power stroke for every two cycles of the piston (or four piston strokes).
Which is faster 2 stroke or 4 stroke?
