METHOD AND DEVICE FOR COOLING A MOTOR VEHICLE ENGINE

摘要

A method for cooling a motor vehicle engine consists in regulating the volume and the flow rate of a coolant fluid in a hydraulic circuit provided with a degassing bypass hose wherein is provided a degassing box. The method comprises a step of determining the temperature of the cooling liquid, a step of comparing the temperature of the cooling liquid with a first threshold temperature, and a step of regulating the fluid circulation in the degassing bypass hose such that, when the fluid temperature is higher than the first threshold, the amount of fluid circulating in the bypass hose is greater than the amount circulating in that same bypass hose when the fluid temperature is lower than the first threshold temperature. The invention also concerns a device for cooling a motor vehicle engine.
