Title (EN) A METHOD AND APPARATUS FOR CONTROLLING A HCCI INTERNAL COMBUSTION ENGINE WITH TWO INJECTION EVENTS
(FR) PROCEDE DE COMMANDE EN MODE MIXTE ET MOTEUR ASSOCIE
Abstract:
(EN) A method of mixed mode operation of an internal combustion engine (10) includes the steps of controlling a homogeneous charge combustion event timing in a given engine cycle, and controlling a conventional charge injection event to be at least a predetermined time after the homogeneous charge combustion event. An internal combustion engine (10) is provided, including an electronic controller (30) having a computer readable medium with a combustion timing control algorithm recorded thereon, the control algorithm including means for controlling a homogeneous charge combustion event timing and means for controlling a conventional injection event timing to be at least a predetermined time from the homogeneous charge combustion event.
(FR) La présente invention se rapporte à un procédé de fonctionnement en mode mixte d'un moteur à combustion interne (10). Le procédé selon l'invention comprend les étapes consistant à commander un moment d'événement de combustion de charge homogène au cours d'un cycle moteur donné, et à commander un événement d'injection de charge classique de manière qu'il intervienne à au moins un moment prédéterminé après l'événement de combustion de charge homogène. L'invention concerne également un moteur à combustion interne (10), qui comprend un contrôleur électronique (30) doté d'un support lisible par ordinateur sur lequel est enregistré un algorithme de commande du moment de combustion, l'algorithme de commande comportant un moyen permettant de commander un moment d'événement de combustion de charge homogène, et un moyen permettant de commander un moment d'événement d'injection classique de manière qu'il intervienne à au moins un moment prédéterminé à partir de l'événement de combustion de charge homogène.
