Abstract
The cooling circuit of an internal combustion engine of a vehicle includes a thermally insulated reservoir having an inlet duct and an outlet duct. These ducts are connected to the mass of air in a head space either within the expansion vessel in the cooling circuit or within the reservoir itself, in such a way that the inlet and outlet ducts become filled with air when the motor is stopped. This air then physically separates the liquid in the reservoir from that contained in the rest of the circuit, so reducing heat losses.
