Before about 2 years, Liquidpiston had presented to the public the X2, a rotary motor with thermodynamic efficiency of 75%. Now Liquidpiston presented the X Mini with a weight not exceeding 1.5 kg and dimensions comparable to that of a smart phone, which can be adapted for a variety of applications.
TX Mini is not Wankel, it Operates on the “High Efficiency Hybrid Cycle” of Liquidpiston, having a much higher compression than the Wankel, without the high emissions of the Wankel and finally, the apex seals are not in the rotor but in the crankcase, which means that the engine does not consume oil.
On the other hand, the alpha prototype has a capacity of 70 ml and yields 3.5 hp. And when it will go into production, it will produce more than 5 hp at 15,000 rpm Also important is the fact that it does not vibrate or produce noise.
Liquidpiston believes that the X Mini will allow applications that were not possible with existing technology while at the beginning of 2015, they will launch a competition in which participants can submit their idea for an application of the engine.
In my opinion it would be a perfect range extender on electric vehicles.
