Hi Paul,

Has anyone any experience with converting a rotary to steam??

I'm working with a guy who is building a Pietenpol and has built a 3
cylinder radial steam engine for it. He is a 'traditional' guy and
whenever I bring up the subject of the Wankel rotary i get subjected to
a barrage of abuse and negativity. (It wont breathe, the apex seals will
melt, etc, etc).

Does anyone have any Ammo I can fire back?? Studies done??

Thanks, Russ Ward


The rotary would make a fine steam engine.  Every third revolution
inject water and
not gasoline. Eliminates the cooling system as well. Patent applied for.

I wonder if such an engine would be practical.  Would water evaporate that fast?
We are talking about a few thousand RPM

It has been tested in a piston engine.

"The six-stroke engine is a type of internal combustion engine based on the four-stroke engine Four-stroke_engine, but with additional complexity intended to make it more efficient and reduce emissions. Two types of six-stroke engine have been developed since the 1890s:"

"The pistons in this type of six-stroke engine go up and down three times for each injection of fuel. There are two power strokes: one with fuel, the other with steam. The currently notable designs in this class are the Crower six-stroke engine invented by Bruce Crower of the U.S.; the Bajulaz engine  by the Bajulaz S.A. company of Switzerland; the Velozeta Six-stroke engine built by the College of Engineering, at Trivandrum in India; and the NIYKADO Six Stroke Engine invented by Chanayil Cleetus Anil, NIYKADO Motors, India under patent number IN252642 granted on 25 May 2012."

It is a form of turbo compounding as the otherwise waste cooling heat is used to vaporize the
water and turn it into steam.

"The enthalpy of vaporization is the energy required to turn water into the gaseous form when it increases in volume by 1,600 times at standard temperature and pressure; this change in volume can be converted into mechanical work in a piston engine  and  in steam turbines."
