Patent

CA 2266593

A method and system (10) for the control of the fuel injection timing in an internal combustion engine (12) using a low cetane quality fuel such as an aqueous fuel emulsion (16) is provided. The disclosed system includes a compression ignition engine (12) adapated to receive a prescribed supply of an aqueous fuel emulsion (16). The prescribed supply of fuel is preferably determined by a fuel system control unit (22) as a function of one or more engine operating parameters. The disclosed system also includes an exhaust sensor (34) located proximate imate the engine exhaust (32) so as to detect the presence and level of selected exhaust products, such as carbon monoxide, in the engine exhaust (32). The level of carbon monoxide or other such exhaust product, as measured by the sensor (34), is input to the engine control unit (22) where it is processed together with various other engine operating parameters (25, 27, 29) to produce a prescribed fuel injection timing signal (36) which operatively controls the fuel injection timing.

L'invention porte sur un procédé et un système (10) de réglage de l'avance d'injection dans un moteur à combustion interne (12) utilisant un carburant à faible indice de cétane tel qu'une émulsion aqueuse (16) de carburant. Ledit système consiste en un moteur (12) à allumage par compression conçu pour recevoir une quantité prescrite d'émulsion aqueuse (16) de carburant déterminée de préférence par un régulateur (22) d'alimentation en fonction d'un ou plusieurs des paramètres de fonctionnement du moteur. Ledit système comporte également une sonde (34) d'échappement située à proximité de l'échappement (32) et détectant la présence et le taux de produits d'échappement sélectionnés, tels que le CO, dans les gaz d'échappement (32). La teneur en CO et autres produits d'échappement analogues mesurée par la sonde (34) est introduite dans le régulateur (22) et traitée avec d'autres paramètres (25, 27, 29) de fonctionnement du moteur pour produire le signal (36) d'avance d'injection qui commande l'avance d'injection.
