Title (EN) METHOD OF OPERATING AN ENGINE WITH A MIXTURE OF GASEOUS FUEL AND EMULSIFIED PILOT FUEL TO REDUCE NITROGEN OXIDE EMISSIONS
(FR) TECHNIQUE DE FONCTIONNEMENT D'UN MOTEUR AU MOYEN D'UN MELANGE DE CARBURANT GAZEUX ET DE CARBURANT PILOTE EMULSIONNE AUX FINS D'UNE REDUCTION DES EMISSION D'OXYDES D'AZOTE
Abstract: front page image
(EN)Reduction of nitrogen oxide emissions during operation of an engine (10) is achieved by using a fuel mixture therein which includes a gaseous fuel (36) and an emulsified pilot fuel (38). The method includes the steps of (i) advancing air into a combustion chamber (28) of the engine (10), (ii) advancing a gaseous fuel (36) into the combustion chamber (28), (iii) injecting an emulsified pilot fuel (38) into the combustion chamber (28), wherein the emulsified pilot fuel (38) includes water and liquid fuel, and (iv) compressing a mixture which includes (A) the air, (B) the gaseous fuel (36), and (C) the emulsified pilot fuel (38) within the combustion chamber (28) during a compression stroke of the engine (10), whereby heat generated by compression of the mixture causes the emulsified pilot fuel (38) to combust so as to ignite the gaseous fuel (36).
(FR)On parvient à réduire les émissions d'oxydes d'azote d'un moteur (10) en utilisant un mélange de carburants constitué de carburant gazeux (36) et de carburant pilote émulsionné (38). Cette technique comporte les phases suivantes: (i), introduction d'air dans la chambre de combustion (28) du moteur (10), (ii), introduction de carburant gazeux (36) dans la chambre de combustion (28), (iii), injection d'un carburant pilote émulsionné (38) dans la chambre de combustion (28), ce carburant pilote émulsionné étant constitué d'eau et de carburant liquide, et, (iv), compression du mélange constitué, (A), d'air, (B), de carburant gazeux et, (C), de carburant pilote émulsionné (38), dans la chambre de compression (28) lors du temps de compression du moteur (10). La chaleur produite par cette compression entraîne la combustion du mélange de carburant pilote émulsionné (38), ce qui provoque l'allumage du carburant gazeux (36).
