METHOD OF COOLING AND COOLING SYSTEM OF INTERNAL COMBUSTION ENGINE Russian patent published in 1996 - IPC

FIELD: mechanical engineering; engines. SUBSTANCE: two-circuit cooling system of internal combustion engine has engine cooling spaces in first circuit and water-to-oil heat exchanger and supercharging air heat exchanger in second circuit. Temperature of cooling liquid in first circuit is regulated by changing flow of air delivered for blowing the radiator of first circuit, oil temperature is regulated by successively changing flow of oil bypassing water-to-oil heat exchanger and flow of air delivered for blowing out radiator of second circuit. Cooling liquid temperature in second circuit is checked at outlet of superchanging air heat exchange and is regulated by successively changing flows of cooling liquid passed from first circuit into second circuit and air delivered for blowing out radiator of second circuit. EFFECT: increased economy of engine by enhancing quality of regulation of heat carrier temperature, enhanced reliability of cooling system. 5 cl, 4 dwg
