AIR-STEAM INTERNAL COMBUSTION ENGINE Russian patent published in 2014 - IPC F02G5/02 F01K23/14 F02B41/00 

FIELD: engines and pumps.

SUBSTANCE: invention can be used in engine-construction. Air-steam internal combustion engine contains piston engine (1) of internal combustion, high pressure steam drum (2), radiator (4), screw steam engine (3), radiator (4), high pressure liquid pump (6), storage tank (5), feeding tank (8) and heat insulation of engine (1) case and drum (2) of high pressure steam from the environment. Cooling and heat discharge from piston engine (1) of internal combustion is realized by refrigerating liquid with lower boiling temperature and cooling jacket, used as steam-producing boiler, connected with high pressure drum (2). In drum (2) increase of steam temperature is achieved due to heating with exhaust gases passing through drum. Conversion of steam heat energy into additional mechanical work is realised by screw steam engine (3). Steam, cooled after expansion in screw steam engine (3), by means of radiator (4) installed in condensation contour is condensed into liquid, which is supplied from storage tank (5), connected with feeding tank (8) through check valve into cooling jacket of piston engine (1) of internal combustion by high pressure liquid pump (6) for re-use.

EFFECT: increase of steam temperature in drum of stream-producing boiler.
