Each chamber has one power pulse. So each rotor revolution produces three power pulses, which is similar to the output from a single cylinder 2-stroke engine.
What if two rotors are bolted together?
Then their output is similar to that of a twin-cylinder 2-stroke engine.
Because of the ratio of the gears in the housings and rotor, the eccentric shaft makes one revolution for each power phase. That’s the same as three revolutions for each rotation of the rotor. So the eccentric shaft turns at three times the speed of the rotor.
