METHOD AND DEVICE FOR REGENERATING EXHAUST GASES Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: exhaust gases are separated into two streams at the engine outlet. The high-temperature of one of the stream is conserved up to the fuel mixture manifold. The other stream is cooled and delivered to the receiver together with water condensate. The cooling water is then sprayed from the receiver with exhaust gas presented in it as portion of high-temperature gas which have been supplied to the fuel mixture manifold, maximal temperature of exhaust gases being bounded by 550°C. The required temperature difference between the streams is maintained when rarefication (or positive pressure) occurs in the system. This can be achieved by abrupt decreasing of the temperature of sprayed water owing to evaporation of dissolved carbon dioxide when dust fractions of water enter the system of the fuel mixture manifold which is somewhat evacuated in operation of the engine and by restriction of the temperature regime by high-temperature exhaust gas resulting in excluding dissociation of molecules of dust fractions of water into hydrogen and oxygen. EFFECT: enhanced efficiency. 3 cl, 1 dwg
