FIELD: engines and pumps.
SUBSTANCE: invention relates to ICE with splitted thermodynamic cycle. This invention consists in that two, suction and compression, strokes are realised in one cylinder with piston while two other, working stroke and discharge, cycles are implemented in another cylinder with piston. Gas combustion and primary expansion occur in separate heat-insulated device with gas receiver for first gas expansion step to be executed for further feed into working engine. Gas pressure and temperature decrease in said receiver due to significant volume but relatively constant gas pressure is maintained under conditions of heat insulation. Working gas second expansion occurs in working engine, in cylinder with piston, whereto constant-pressure gas is fed from receiver. Gas temperature is decreased, second time, to minimum possible value and gas is ejected into atmosphere.
EFFECT: engine operation without cooling system, hence, higher engine efficiency.
