<p>Method for control of cooling by means of an air flow configuration of a motor vehicle's cooling fan (1) whereby at least one cooling device (2; 2', 2'), e.g. a radiator (2) for radiator liquid and a cooler (2') for charge air for the engine, is/are air-cooled by an air flow generated by inter alia the fan, comprising the step of determining said air flow configuration by the fan's degree of protrusion (a) from a fan ring (4) running in the circumferential direction of the fan, preferably in air flow communication with a fan cowling (3). The method is distinguished particularly by the step of - optimising the air flow configuration in a manner controlled according to need by said degree of protrusion (a) by relocation of a movable portion (6) of said fan ring (4) in the axial direction (1 ') of the fan (1). The invention relates also to a device and an engine.</p> |
