Title (EN) INTERNAL COMBUSTION ENGINE START-UP OPERATING MODE AND ENGINE USING SAME
(FR) MODE DE FONCTIONNEMENT DE DÉMARRAGE DE MOTEUR À COMBUSTION INTERNE ET MOTEUR UTILISANT CELUI-CI
Abstract:
(EN) A method of initially operating an internal combustion engine (10) including operating the engine (10) in a start-up mode is provided. The start-up mode includes injecting at least two fuel pre-shots wherein a first of the fuel pre-shots is smaller in quantity than a last of the fuel pre-shots. An engine (10) is provided including an electronic controller (40) with a computer readable medium having a control algorithm recorded thereon, the control algorithm including means for commanding injection of a main fuel shot and at least two fuel pre-shots wherein a first of the fuel pre-shots is smaller in quantity than a last of the fuel pre-shots.
(FR) La présente invention concerne un procédé de fonctionnement initial d’un moteur à combustion interne (10) comprenant le fonctionnement du moteur (10) dans un mode de démarrage. Le mode de démarrage comprend l’injection d’au moins deux pré-giclées de carburant dans lesquelles une première des pré-giclées de carburant est plus petite en quantité qu’une dernière des pré-giclées de carburant. Un moteur (10) est prévu comprenant un dispositif de commande électronique (40) avec un support pouvant être lu par un ordinateur ayant un algorithme de commande enregistré sur celui-ci, l’algorithme de commande comprenant des moyens pour commander l’injection d’une giclée de carburant principale et au moins deux pré-giclées de carburant dans lesquelles une première des pré-giclées de carburant est plus petite en quantité qu’une dernière des pré-giclées de carburant.
