A new family of compact, light weight Wankel engines for multi-purpose applications was designed and is currently under an optimization test.
The engine short block with fewer parts reaches the pinnacle in the simplicity of the rotary combustion engine design concept.
New technological solutions have been employed in the design of the cooling, ignition and lubrication systems in order to lower the engine maintenance and operating costs.
The paper describes the primary components and systems of the engine and much of the design and development work that led to the validation of the new design.
The single rotor and two rotor engines cover a power range of 5-50Kw when naturally aspirated, with a weight to power ratio close to 1 lbs/lhp. The design concept demonstrated a high potential for turbocharged applications. Unparalleled weight to power ratio are estimated for the fully developed turbocharged version of both engines. The new engines are suitable for diverse stationary and mobile applications in which weight, box volume and vibration are strict constraints.
