FIELD: engines and pumps.
SUBSTANCE: invention relates to machine building, particularly to internal combustion engines. ICE cooling system comprises coolant circulation circuit, liquid pump, engine cooling jacket and radiator, confuser-diffuser device connected to aforesaid coolant circulation circuit and expansion tank. The latter is connected, via steam bleeder, to engine cooling jacket and, via discharge pipeline, to confuser-diffuser device. In compliance with this invention, proposed system comprises heat exchanger incorporate with expansion tank steam-air section to heat steam-air mix by exhaust gas heat, connected parallel to exhaust gas discharge line. It comprises also temperature and pressure pickups arranged in liquid pump inlet, control unit and waste gas flow rate metre.
EFFECT: higher pressure at liquid pump inlet and its adjustment.
