Abstract:
Method for cooling a motor vehicle engine, which consists in regulating the volume and the flow rate of a cooling fluid in a hydraulic circuit provided with a degassing branch in which is arranged a degassing box, wherein the method comprises:a step of determining the temperature (T) of the cooling liquid, a step of comparing the temperature of the cooling liquid with a first threshold temperature (T1), a step of regulating the circulation of fluid in the degassing branch so that, when the temperature (T) of the fluid is higher than a first threshold temperature (T1), the quantity of fluid circulating in the degassing branch is greater than the quantity of fluid circulating in that same branch when the temperature (T) of the fluid is lower than the first threshold temperature (T1), and a step of comparing the temperature (T) of the cooling fluid with a second threshold temperature (T2), so that, when the temperature (T) of the fluid is higher than the second threshold temperature (T2), the quantity of fluid allowed to circulate in the degassing branch is greater than the quantity of fluid allowed to circulate in that same branch when the temperature (T) of the fluid is lower than the second threshold temperature (T2).
