Above one can see the single cylinder, 4 stroke 150 cc demonstrator as built for the patent application and in the " Videos " page you will readily notice its smooth operation. Although the innovative Rotary Piston engine is affixed on a cantilever type support, one will immediately see it virtually does not vibrate or oscillate, something amazing and which is traditionally unheard of for a single cylinder engine. To testify for its performance, low weight and small footprint, we compare below our newly designed single cylinder, 4 stroke 250 cc Rotary Piston engine in a 10 KW electric generation application versus one of today's common unit we currently find on the market. Since our Rotary Piston engine has high torque and is already running at the ideal RPM regime, it allows to have a direct drive without any transmission. Our engine is dynamically air cooled which also alleviates the need for a bulky liquid cooling system. Such an advanced generator solution will prove attractive as a performant and lightweight Range Extender in tomorrow's hybrid vehicles, as a Auxiliary Power Units (APU) required worldwide in the trucking industry, and in any other applications were electric energy is immediately needed. Also, the inherent superior features of the innovative Rotary Piston engine make it the best candidate for drones or UAV applications. It has an extremely low vibration level, small and lightweight as well as high torque at the required propeller's RPM. More fuel or payload may be carried along for an extended range.
