X-mini is manufactured in accordance with the own design of the rotor engine developed by LiquidPiston. The thermodynamic cycle of the technology gives a much higher efficiency than the conventional Wankel rotary engine or traditional reciprocating engines.
According to LiquidPiston, the engine is at the testing stage. At present only one working prototype is built. In the future, it is planned to reduce the weight of the engine to 1.5 kg and raise the power to 5 hp.
Last year, the LiquidPiston startup received a $ 1 million grant from DARPA to develop an innovative compact engine. A small and light motor is planned to be used in drones , as a marching generator or even in military robotics.
