Title (EN) FUEL SUPPLY SYSTEM AND METHOD FOR SUPPLYING FUEL TO A COMBUSTION CHAMBER
(FR) SYSTÈME D'ALIMENTATION EN CARBURANT ET PROCÉDÉ POUR ALIMENTER UNE CHAMBRE DE COMBUSTION EN CARBURANT
Abstract:
(EN) The invention concerns a fuel supply system for injecting under high pressure at least a first and a second fuel in a combustion chamber (2-5) of a combustion engine. The fuel supply system comprises a high pressure rail (11) with an or a plurality of injectors for injection of fuel into the combustion chamber (2-5). The fuel supply system is arranged to, in a first state, inject under high pressure via the high pressure rail (11) a petrol to the combustion chamber (2-5) of the combustion engine. The fuel supply system is arranged to, in a second state, inject under high pressure via the high pressure rail (11) a liquefied vapour, such as liquefied petroleum gas (LPG), to the combustion chamber (2-5) of the combustion engine. The fuel supply system is also arranged to supply, in the second state, liquefied vapour to the combustion chamber (2-5) via an air inlet (32).
(FR) L'invention porte sur un système d'alimentation en carburant pour injecter sous haute pression au moins un premier et un second carburant dans une chambre de combustion (2-5) d'un moteur à combustion. Le système d'alimentation en carburant comprend une première rampe haute pression (11) avec un ou plusieurs injecteurs pour l'injection de carburant dans la chambre de combustion (2-5). Le système d'alimentation en carburant est agencé pour, dans un premier état, injecter sous haute pression, par l'intermédiaire de la rampe haute pression (11), une essence dans la chambre de combustion (2-5) du moteur à combustion. Le système d'alimentation en carburant est agencé pour, dans un second état, injecter sous haute pression, par l'intermédiaire de la rampe haute pression (11), une vapeur liquéfiée, telle qu'un gaz de pétrole liquéfié (LPG), dans la chambre de combustion (2-5) du moteur à combustion. Le système d'alimentation en carburant est également disposé pour fournir, dans le second état, de la vapeur liquéfiée à la chambre de combustion (2-5), par l'intermédiaire d'une entrée d'air (32).
