Title (EN) COMMON-RAIL FUEL INJECTION METHOD FOR DIESEL ENGINES
(FR) PROCEDE D'INJECTION DE CARBURANT PAR RAIL COMMUN POUR MOTEURS DIESEL
Abstract: front page image
(EN)An injection method presenting, in addition to the main injection phase, an auxiliary pre-injection phase during the induction stroke of the engine. The pre-injection phase is preferably performed at the start of the induction stroke, and provides for injecting a small quantity of fuel equal to a few percent of the fuel quantity injected during the main injection phase, so that, during the compression stroke, partially oxidized and/or peroxidized products with a strong chemical affinity are formed, and which act as combustion accelerators for minimizing fuel ignition lag of the main injection phase and so reducing the nitric oxides and noise produced during combustion.
(FR)Procédé d'injection comprenant, en plus de la phase d'injection principale, une phase de préinjection auxiliaire pendant la course d'admission du moteur. La phase de préinjection s'effectue de préférence au début de la course d'admission, et consiste en l'injection d'une petite quantité de carburant égale à un faible pourcentage de la quantité de carburant injectée au cours de la phase d'injection principale, de manière à former, pendant la course de compression, des produits partiellement oxydés et/ou peroxygénés à forte affinité chimique servant d'accélérateurs de combustion permettant de réduire au minimum le délai d'allumage du carburant dans la phase d'injection principale, et de réduire ainsi la production d'oxydes nitriques et le bruit pendant la combustion.
