Abstract (en)
[origin: EP0731260A1] The regulation system has a control device (5) for adjusting the revs of the coolant circulation pump (3) and the fan (4) directing air through the radiator, in dependence on the required temp of the engine coolant. The heating-up phase for the engine is shortened by reducing the output of the circulation pump and the fan after starting the engine until the engine coolant reaches a given temp threshold, above which the regulation for maintaining the required coolant temp is brought into operation.
