We have been working on Wankel rotary engines since 1996. Initially the approach was to make a 4-stroke karting engine that would be more powerful, more reliable and more fun than existing 2-stroke engines, which were about to be banned for emissions reasons.
In the meantime our engines are used in a variety of applications beyond karting, for example in manned and unmanned airplanes and helicopters, boats, vehicles of all sorts as well as generators.
The particular advantages of rotary engines are a lack of vibration due to fully dynamically balanced rotating masses, a very compact design, high performance with a very flat torque curve, as well as low emissions.
Our engine designs are known and sold under the brand of Aixro, which we distribute exclusively. Below is some information on the engines. For those interested in some of the technical background of the engines, here is an interesting article in Unmanned Systems Technology Magazine.
