Title (EN) APPARATUS AND METHOD FOR IGNITING A GASEOUS FUEL IN A DIRECT INJECTION INTERNAL COMBUSTION ENGINE
(FR) DISPOSITIF ET PROCÉDÉ D'ALLUMAGE D'UN CARBURANT GAZEUX DANS UN MOTEUR À COMBUSTION À INJECTION DIRECTE
Abstract:
(EN) An apparatus and method for igniting a gaseous fuel directly introduced into a combustion chamber of an internal combustion engine comprises steps of heating a space near a fuel injector nozzle; introducing a pilot amount of the gaseous fuel in the combustion chamber during a first stage injection event; controlling residency of the pilot amount in the space such that a temperature of the pilot amount increases to an auto-ignition temperature of the gaseous fuel whereby ignition occurs; introducing a main amount of the gaseous fuel during a second stage injection event after the first stage injection event; and using heat from combustion of the pilot amount to ignite the main amount.
(FR) L'invention concerne un dispositif et un procédé d'allumage d'un carburant gazeux introduit directement dans une chambre de combustion d'un moteur à combustion interne. Le procédé comprend les étapes consistant à chauffer un espace proche d'une buse d'injecteur de carburant ; introduire une quantité pilote du carburant gazeux dans la chambre de combustion pendant un événement de première étape d'injection ; régler le temps passé par la quantité pilote dans cet espace en vue d'augmenter la température de la quantité pilote à la température d'auto-allumage du carburant gazeux, à laquelle l'allumage se produit ; introduire une quantité principale du carburant gazeux pendant un événement de deuxième étape d'injection, ultérieur à l'événement de première étape d'injection ; et utiliser la chaleur provenant de la combustion de la quantité pilote pour allumer la quantité principale.
