The invention relates to heat engines and, more specifically, to positive displacement internal combustion engines, and is particularly concerned with very large rotary internal combustion engines fueled by solid particulate fuels like coal dust, destined to drive electric current generators, and intended to replace large steam turbines offering at least 50% overall efficiency typical for large Diesel engines, in comparison with ~40% overall efficiency of typical steam boiler-steam turbine assembly. Thus the invention solves the problem of building very large internal combustion positive displacement engines capable of revolving with very large rotational speeds (e.g. 3000-3600 rev./min, like steam turbines) and developing very large outputs (2000 MW and more), as well as problems of fueling internal combustion engines by solid particulate fuels, and removing unburned solid residues from combustion chamber of internal combustion engine. The invention provides the optimal form for the two stroke rotary engine of unique simplicity, strength and compactness, and sealing as simple and robust as that of the ordinary piston engine.

The engine according to this invention is a two stroke engine with only one major moving part, namely engine's eccentric shaft, with cylinders encompassing eccentrics of the shaft, with said eccentrics being suitable sealed in said cylinders, wherein combustion gases exert force directly on said eccentrics of said eccentric shaft. Gas forces can be nullified by suitable 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.
