Abstract:
A cooling system for an internal combustion engine of a motor-vehicle presenting a circuit for a coolant of the engine. The circuit includes a thermally insulated tank for the coolant of the engine, connected to an outer portion of the cooling circuit. The tank is arranged in the circuit to retain a defined quantity of coolant at a temperature above the ambient temperature when the engine is inactive, and for causing this quantity of coolant to flow, at a temperature above the ambient temperature, into the cooling circuit of the engine, after a subsequent start of the engine, during an engine warm up stage. The circuit also includes an expansion vessel connected to the outer circuit portion of the coolant of the engine. The expansion vessel has a thermally insulated body and constitutes the thermally insulated tank for the engine coolant.

Claim (Index 1):
A cooling system for an internal combustion engine of a motor-vehicle, comprising:\n a cooling circuit for a coolant of the engine, including an inner circuit portion internal to the engine and an outer circuit portion external to the engine, a thermally insulated tank for the coolant of the engine, connected to said outer circuit portion of the cooling circuit, adapted for retaining a defined quantity of the coolant at a temperature above an ambient temperature when the engine is inactive, and provided for causing flowing of this defined quantity of the coolant, at the temperature above the ambient temperature, into the cooling circuit of the engine, after a subsequent start of the engine, during an engine warm up stage, an expansion vessel connected to said outer circuit portion of the coolant cooling circuit of the engine, wherein said expansion vessel has a thermally insulated body and constitutes said thermally insulated tank for the defined quantity of the coolant, wherein: said outer circuit portion also comprises a pump for actuating circulation of the coolant in the cooling circuit, a cooler for a lubrication oil of the engine, a heater the a passenger compartment of the motor-vehicle, a radiator for cooling the coolant and an electronically-controlled distribution valve for controlling flow of the coolant in the cooling circuit, said electronically-controlled distribution valve has an inlet connected to a first duct, which feeds coolant leaving the engine, a first outlet connected to an inlet of the lubrication oil cooler of the engine, a second outlet connected to an inlet of said passenger compartment heater, and a third outlet connected to an inlet of said radiator, an electronic control unit for controlling an operating condition of said electronically-controlled distribution valve as a function of one or more operating parameters, including at least one detected value of temperature of the coolant, said expansion vessel is interposed in a second duct, which connects said first duct to an inlet for the coolant into said engine, said pump being interposed in a terminal portion of said second duct downstream of said expansion vessel and said expansion vessel being in a higher position compared to said pump, said electronically-controlled distribution valve is selectively switchable between one of the following operating conditions: a closed condition, wherein all of the first, second and third outlets are isolated with respect to said inlet of the distribution valve, a first open condition, wherein only said first outlet communicates with the inlet of the distribution valve, a second open condition, wherein only the first and second outlets communicate with the inlet of the distribution valve, and a third open condition, wherein all the said first, second and third outlets communicate with said inlet of the distribution valve.
