Patent ID: 7011049

Claim:
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 bypass branch equipped with an electronically controlled proportional actuator and provided with means forming direct return of fluid or bypass, the method comprising: a step of determining the temperature (T) of the cooling fluid, a step of comparing the temperature (T) determined with a first (T 1 ) and a second (T 2 ) specified threshold temperatures, and a step of controlling the opening of the actuator, so that, when the temperature (T) of the fluid is between the first (T 1 ) and the second (T 2 ) threshold temperatures, the degree of opening of the actuator at least temporarily increases when the temperature (T) of the fluid increases and decreases when the temperature (T) of the fluid decreases.
