In the traditional design of the crankshaft in the internal combustion engines, the expansion stroke in ICE produces every two revolutions for the crankshaft. In the new design, one revolution for the crankshaft can produce two expansion strokes. That's not only when returning to the power equation
P= 2.pi.n.T
where
P is the Engine Power
T is the Engine Torque
n is the engine revolution rps

when n reduces to 1/4, that's means the torque it will increase 4 times at the same engine power
and there are many advantage for the new design
