Abstract: A method for controlling an internal combustion engine that includes a booster system including a turbocharger, an exhaust gas recirculation system including a recirculation valve and an electronic control unit for controlling geometrical configuration of the turbocharger and the recirculation valve of the recirculation system. The method detects variation of an acceleration command of the internal combustion engine when the booster system operates according to a first controlled operating mode, switches the booster system to a transitory operating mode according to the detected variation, wherein the turbocharger is maintained in a given geometrical configuration for a predetermined time, and switches the booster system to a second controlled operation mode.

Abstract: The invention relates to a method for controlling an internal combustion engine (1) which comprises a booster system provided with a turbocharger (6, 8), an exhaust gas recirculation system (12) provided with a recirculation valve (13) and an electronic control unit (14) for controlling the geometrical configuration of the turbocharger (6, 8) and the recirculation valve (13) of the recirculation system. The inventive method consists in detecting the variation of the acceleration command of the internal combustion engine (1), when the booster system operates according to a first controlled operating mode (BF, BF?), in switching the booster system to a transitory operating mode (BO2, BO2?) according to the detected variation, wherein the turbocharger (6, 8) is maintained in a given geometrical configuration for a predetermined time, and in switching the booster system to a second controlled operation mode (BO1, BO1?).
