Hi Group:

Is it possible to quantify the diminished smoothness of
the single rotor engine over the std. 2 rotor engine.
One of our helicycle builders group had some concern
that the power pulses of the single rotor could in time
degrade the transmission gears.  BTW, the transmission
is of very high quality and there would be a 6 vee belt
link between the engine and trans.

TIA

The dotted line is the torque fluctuations of the one rotor.
Very severe to say the least.

The torque pulses of a single rotor Wankel are the same as a 3 cylinder
4 stroke engine, and a bit more severe than a 2 cylinder 2 stroke. The
multi Vee belt will go a long way toward protecting the trans, and
I would expect it to be OK - Vance

Are you sure that is not a two cylinder four stroke Vance with one torque pulse
per revolution? The two rotor is the same as a four cylinder four stroke with
two torque pulses per revolution.  The one rotor is the same as a one cylinder
two stroke engine with one torque pulse per revolution. 
I think you still have not figured out the wankel :-)>
