Abstract
At least one cooling device for a motor vehicle is aircooled by an air flow generated by a cooling fan of the motor vehicle. An air flow configuration of the cooling fan is determined by the fan's degree of protrusion from a fan ring running in the circumferential direction of the fan, preferably in air flow communication with a fan cowling. The air flow configuration is optimized in a manner controlled according to need by relocation of a movable portion of the fan ring in an axial direction of the fan. The disclosed method of controlling the air flow configuration is summarized above. A device performing the method and an engine for the motor vehicle including the device are also disclosed.
