Rotary positive displacement internal combustion two stroke engine with only one major moving part, i.e. engine's eccentric shaft, with cylinders encompassing eccentrics of the shaft, with said eccentrics being suitably sealed in said cylinders, wherein combustion gases exert force directly on said eccentrics of said eccentric shaft. Gas forces can be nullified by suitably phasing shaft's eccentrics, thus nullifying gas forces loading shaft's bearings. The engine is naturally perfectly balanced. The engine possesses natural self-cleaning capability, and is capable of being fueled by coal dust. Units of the type developing 2 000 MW and 3 000-3 6000 rev/min, intended to replace steam turbines in power stations, can be built. |
