An apparatus and method for adjusting a quantity of fuel delivered to an engine when an engine operating state transitions is provided. The apparatus and method includes determining a current steady-state quantity of fuel to be delivered to the engine and add a transitory quantity of fuel, based on a difference between a previous steady-state quantity of fuel delivered and the current steady-state quantity of fuel to be delivered, to the current steady- state quantity of fuel for a period of time following initiation of the transition. The invention also provides an apparatus and method by which an operator may adjust the amount of fuel delivered during an engine operating state transition.

L'invention concerne un appareil et un procédé permettant d'ajuster une quantité de combustible distribué à un moteur, lors de transitions d'état de fonctionnement d'un moteur. Cet appareil et ce procédé consistent à déterminer une quantité de combustible en régime stable actuelle à distribuer au moteur, et à ajouter une quantité de combustible transitoire, en fonction d'une différence entre une quantité de combustible en régime stable antérieure distribuée et la quantité de combustible en régime stable actuelle à distribuer, à la quantité de combustible en régime stable actuelle, pendant une certaine durée, en fonction du début de la transition. L'invention concerne également un appareil et un procédé permettant à un opérateur d'ajuster la quantité de combustible distribué lors d'une transition d'état de fonctionnement d'un moteur.
