Abstract

L'invention concerne un procédé de commande d'un moteur thermique suralimenté comprenant un circuit d'admission (2) de gaz d'admission, avec un compresseur de turbocompresseur (21) et un compresseur additionnel (25), un circuit d'échappement (3) avec une turbine de turbocompresseur (31) à géométrie variable couplée en rotation au compresseur de turbocompresseur (21), et un circuit de recirculation des gaz d'échappement (33) vers un collecteur d'admission (25) du circuit d'admission. En cas d'activation du circuit de recirculation des gaz d'échappement, si le compresseur additionnel est en fonctionnement, on commande des éléments (310) de changement de géométrie de la turbine à géométrie variable (31) de façon à augmenter la pression (PAVT) à l'échappement en amont de la turbine à géométrie variable, de sorte à rétablir une différence de pression positive entre la pression à l'échappement en amont de la turbine à géométrie variable et une pression de suralimentation dans le collecteur d'admission.The invention relates to a method for controlling a supercharged heat engine comprising an intake circuit (2) of intake gas, with a turbocharger compressor (21) and an additional compressor (25), an exhaust circuit (3) with a turbocharger turbine (31) of variable geometry coupled in rotation to the turbocharger compressor (21), and an exhaust gas recirculation circuit (33) to an intake manifold (25) of the circuit d 'admission. If the exhaust gas recirculation circuit is activated, if the additional compressor is in operation, the geometry change elements (310) of the variable geometry turbine (31) are controlled so as to increase the pressure ( PAVT) to the exhaust upstream of the variable geometry turbine, so as to re-establish a positive pressure difference between the exhaust pressure upstream of the variable geometry turbine and a boost pressure in the intake manifold .
