INTERNAL COMBUSTION ENGINE SUPERCHARGING PRESSURE CONTROL DEVICE Russian patent published in 2007 - IPC F02M37/12 F02M25/22 

FIELD: mechanical engineering; internal combustion engines with supercharging.

SUBSTANCE: proposed device to control supercharging pressure of internal combustion engine had turbosupercharge with compressor having air pressure line connected with engine combustion chamber through mixer of products of pyrolysis and air, and drive steam turbine whose inlet is connected with outlet of water-steam space of cooling-evaporating set, and outlet is connected with mixer of fuel fumes and water steam. Device is furnished with evaporating heat accumulating set with housing accommodating rigidly installed outer and inner cylindrical pipes. Surface of inner pipes is ribbed. Space between inner and outer pipes is filled with heat-accumulating material, for instance, alloy of aluminum and silicon. Holes are made in lower part of evaporating heat-accumulating set and nozzles connected with water pump are fitted in said holes. Inlet of steam turbine is connected with outlet of steam space of evaporating heat-accumulating set by means of pipelines connected by branch pipe. Evaporating heat accumulating set is arranged in exhaust manifold.

EFFECT: reduced toxicity, increased economy and efficiency of internal combustion engine in operation.
