Title
(EN) IGNITION-ASSISTED FUEL COMBUSTION SYSTEM
(FR) SYSTEME DE COMBUSTION DE CARBURANT AIDE PAR ALLUMAGE
Abstract
(EN)
Conventional direct injection internal combustion engines will not completely ignite and burn relatively lower-cetane-number fuels such as 100 percent methanol or ethanol because the fuel spray injection pattern usually cannot carry or propagate a flame to all the injected fuel which is typically made up of individual fuel streams which are separated by pockets of fuel-deficient intake air. The present fuel combustion system (10) includes a fuel ignition-initiating device (26) such as a glow plug (70) and apparatus (98, 102) for interconnectedly contacting and continuously bridging all of the individual fuel streams (66) with an auxiliary cloud (94) of well-atomized fuel. In this manner, a flame initiated by the fuel ignition-initiating device (26) is rapidly and completely propagated via the auxiliary cloud (94) of fuel to all the individual fuel streams (66).
(FR)
Les moteurs à combustion interne conventionnels à injection directe n'allument pas ni brûlent complètement des carburants à indice de cétane relativement bas, tels que l'éthanol ou le méthanol à 100 pour cent, étant donné que le jet pulvérisé de carburant injecté ne peut en général communiquer ou propager une flamme à la totalité du carburant injecté, lequel se compose généralement de courants individuels de carburant séparés par des poches d'air d'admission pauvre en carburant. Le système de combustion de carburant ci-décrit (10) comprend un dispostif de déclenchement d'allumage de carburant (26) tel qu'une bougie à incandescence (70) et un dispositif (98, 102) permettant de relier par contact et d'unir en continu tous les courants individuels de carburant (66) à l'aide d'un nuage auxiliaire (94) de carburant bien atomisé. De cette manière, une flamme déclenchée par le dispositif de déclenchement d'allumage de carburant (26) peut se propager rapidement et complètement par l'intermédiaire du nuage auxiliaire (94) de carburant à tous les courants individuels de carburant (66).
