COOLING SYSTEM OF INTERNAL COMBUSTION ENGINE Russian patent published in 2007 - IPC F01P3/20 F01P11/08 

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: proposed cooling system of internal combustion engine provides heating of car saloon using heat of circulating liquid passing through cylinder block cooling jacket, cooling channels of cylinder head and liquid-oil heat exchangers, into heater radiator. System is furnished with three-way cock through which heated cooling liquid gets into heater radiator for heating saloon or returns to water pump. System is provided with circulating electric pump providing intensive cooling of oil in liquid-oil heat exchanger when engine operates under load and intensively heats car saloon. At starting engine from cold, cooling liquid heated in cylinder block and cylinder head, passing through liquid-oil heat exchanger, heats oil and cuts down time required for heating and preparation of engine for taking of load.

EFFECT: provision of effective cooling of engine at operation, heating of car saloon, quick warming and preparation of engine for taking of load when starting from cold.
