There are numerous configurations possible with the ELE Solution. The initial ELE prototype is based on the rotary Wankel as it has 3 moving parts in dual chamber (rotor) form. Another preference is the turbine. However, as over 98% of the world’s engines for power generation and transportation usage are piston engines, the ELE solution is adaptable to convert all existing piston engines. This includes two or four stroke, petrol or diesel, single or multi-cylinder.
