FIELD: mechanical engineering; engines. SUBSTANCE: in process of fuel combustion heat radiation is accumulated owing to partial reflection from combustion chamber surface, reaching its peak at complete combustion of fuel. Temperature of combusted products is maintained further by nitrogen molecules. Engine is heated by heat radiation of combusted products till the end of exhaust (70-90%, depending on cylinder capacity and piston medium speed). With water atomized in combustion chamber by nozzle immediately after combustion of fuel, heat radiation is absorbed by atomized water and steam. When superheated steam is formed, temperature in cylinder drops sharply at short-time increase in pressure in cylinder owing to superheated steam. Mean effective pressure increases and heating of engines becomes such that cooling system is not necessary. Amount of water delivered by high pressure pump is defined by exhaust temperature excluding condensing of steam on turbine blades. Drops of water at temperature of surface from 200 C and higher do not come in touch with surface as distinct from fuel. Water supply system is identical to fuel system of diesel engine. EFFECT: enlarged operating capabilities. |
