A method carried out by a control device, the method holding a valve EGR completely opened during a determined short time after a starting phase of a diesel engine, which is provided with an EGR recirculation, and controlling the valve EGR in a partially closed state during the starting time of the engine to increase the engine speed to a threshold speed corresponding to the end of the starting phase. The control is progressively carried out according to a determined closing instruction via a calibration by using data representative of engine speed and ambient temperature. The dynamically controlled recirculation makes it possible, in particular, to accumulate more fuel at the staring phase without increasing injected quantities, to increase the speed of engine actuated by a starter, and to avoid engine blocking. |
