Title (EN) METHOD AND SYSTEM FOR ADAPTATION OF SUPPLY OF ADDITIVE TO AN EXHAUST GAS STREAM
(FR) PROCÉDÉ ET SYSTÈME D'ADAPTATION DE L'INTRODUCTION D'ADDITIF DANS UN COURANT DE GAZ D'ÉCHAPPEMENT
Abstract: front page image
(EN)The present invention concerns a method for correcting a supply of a first additive for reducing at least a first substance (NOx) present in an exhaust gas stream. The method comprises, in connection with said correction: - determination of a first accumulation (N1) of a representation of said first substance (NOx), wherein said first accumulation (N1) of said first substance (NOx) represents an accumulated amount of said first substance (NOx) downstream of said supply of said first additive; - determination as to whether a first amount of work (W1) has been performed by said combustion engine (101) during the accumulation of said first substance (NOx); - discontinuation of said first accumulation of said first substance (NOx) when said first amount of work (W1) has been performed by said combustion engine (101); and - correction of the supply of said first additive based on said first accumulation (N1) of said first substance (NOx).
(FR)La présente invention concerne un procédé pour rectifier l'introduction d'un premier additif afin de réduire au moins une première substance (NOx) présente dans un courant de gaz d'échappement. Le procédé comprend, conjointement avec ladite rectification : - la détermination d'une première accumulation (N1) d'une représentation de ladite première substance (NOx), ladite première accumulation (N1) de ladite première substance (NOx) représentant la quantité accumulée de ladite première substance (NOx) en aval de ladite introduction dudit premier additif; - la détermination du fait de savoir si une première quantité de travail (W1) a été effectuée par ledit moteur à combustion (101) durant l'accumulation de ladite première substance (NOx); - l'interruption de ladite première accumulation de ladite première substance (NOx) lorsque ladite première quantité de travail (W1) a été effectuée par ledit moteur à combustion (101); et - la rectification de l'introduction dudit premier additif sur la base de ladite première accumulation (N1) de ladite première substance (NOx).
