METHOD OF AND DEVICE TO INCREASE EFFICIENCY OF INTERNAL COMBUSTION ENGINE Russian patent published in 2007 - IPC F02B47/02 F02B47/08 F02B75/02 

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: proposed method consists in accumulation and compression of exhaust gases and injection of water. Part of exhaust gases is cut off from exhaust system by-passing them into accumulating space. Water preliminarily heated by thermally stressed part of engine is injected under pressure into said part of exhaust gases. Exhaust gases are expanded together with formed steam with subsequent repetition of working cycles including compression of exhaust gases together with steam, injection of water and expansion of exhaust gases and steam at working stroke. Then exhaust stroke is performed, and amount of consumed injected water is compensated. Engine is thermally insulated over entire external surface. method is implemented in internal combustion engine containing cylinder, combustion chamber, intake and exhaust valves, camshaft, crankshaft and working piston. Accumulating space is made in exhaust manifold separated from combustion chamber by exhaust valve of combustion chamber and from ambient medium by exhaust valve of accumulating space. Nozzle to inject water by plunger pump is installed in housing of accumulating space, and service reservoir is provided to keep service water.

EFFECT: improved efficiency of engine in operation.
