METHOD FOR OPERATING SEPARATED CIRCUIT OF COOLING LIQUID Russian patent published in 2016 - IPC F01P7/14 F01P7/16 F01P3/02 

FIELD: engines.

SUBSTANCE: invention relates to cooling the combustion engine. Operating method of separated circuit (1) of internal combustion engine coolant, in which there are water jacket (2) of cylinder block head and water jacket (3) of engine block, divided by circuit (1) of cooling fluid has pump (4), radiator (6), element (7) of control, housing (8) outlet and heater (9), wherein cooling fluid circulates in divided by circuit (1) cooling liquid, wherein element (7) of control is made of thermostat (12) and proportional valve that is separate from thermostat, wherein thermostat and proportional valve are located, are connected in parallel, on housing (8) outlet, wherein cooling fluid passing through the proportional valve (13), is carried out through water line (14) of block in water jacket (3) of engine block, through line (16) heater in heater (9) and through line (17) of radiator with radiator (6), wherein cooling fluid passing through thermostat (12) , is carried out through connecting line (18) in radiator (6), wherein thermostat (12) and proportional valve (13), coolant flow through respective line (14, 16, 17, 18) independently from each other, but as function of working modes (31, 32, 33, 34) of internal combustion engine.

EFFECT: invention ensures reduction of fuel consumption and production of harmful emissions, as well as longer life.
