The Wankel engine looks pretty simple. Could I get the plans from you to build my own Rotapower engine?
The manufacture of our engine requires quite a few very specialized tools and processes. The unusual shape of the trochoid housing’s surface (sort of peanut-shaped) is nearly impossible to build without a CNC mill, and the side seal grooves are so thin and deep that they also take a special tool. In addition, once created the wear surfaces require plasma spray coatings to withstand the extreme operating conditions. With all of these requirements, it is a difficult engine to build in small quantities. And that assumes you start with reasonably good castings, which are also a challenge to get in small quantities.
