Abstract (en)
[origin: WO2007083064A2] The invention concerns a device for controlling the opening of a cooling circuit control valve system of an internal combustion engine, containing a coolant, which is automatically opened under the effect of a cooling liquid being heated to a standard temperature. The invention is characterized in that it consists in performing an early controlled opening (230) of the control valve system of a cooling circuit located upstream of a heat exchanger before the temperature of the cooling liquid reaches a set temperature value for activating the opening of the control valve system which is itself lower than the standard temperature, said controlled opening being performed only when the control valve system is first opened.
