Title
(EN) FUEL SYSTEM, KIT AND METHOD FOR DIRECTLY INJECTING A FUEL IN A COMBUSTION ENGINE
(FR) SYSTÈME DE CARBURANT, TROUSSE ET PROCÉDÉ POUR INJECTER DIRECTEMENT UN CARBURANT DANS UN MOTEUR À COMBUSTION
Abstract
(EN) The invention relates to a fuel system and method for a combustion engine with direct injection. The system comprises at least one high pressure fuel line connected to an injection device of the combustion engine for the direct injection of fuel. A first fuel is supplied to the node by a first fuel supply unit. The first fuel supply unit comprises at least a high-pressure fuel pump having an inlet connected to a first fuel storage for a liquid fuel, such as gasoline, and having an outlet connected to the node of the high pressure fuel line. A second fuel supply unit supplies a different fuel to the node in the high pressure fuel line, the second fuel supply comprising at least a second fuel storage for liquefied vapor fuel, such as liquid petrol gas (LPG), and a liquefied vapor fuel pump.
(FR) L'invention porte sur un système de carburant et sur un procédé pour un moteur à combustion à injection directe. Le système comprend au moins une conduite de carburant à haute pression reliée à un dispositif d'injection du moteur à combustion pour l'injection directe du carburant. Un premier carburant est envoyé au nœud par une première unité d'alimentation en carburant. La première unité d'alimentation en carburant comprend au moins une pompe à carburant à haute pression ayant une entrée raccordée à un premier réservoir de carburant contenant un carburant liquide, tel que l'essence, et ayant une sortie raccordée au nœud de la conduite de carburant à haute pression. Une seconde unité d'alimentation en carburant envoie un carburant différent au nœud dans la conduite de carburant à haute pression, la seconde source de carburant comprenant au moins un second réservoir de carburant contenant un carburant sous forme de vapeur liquéfiée, tel qu'un gaz de pétrole liquéfié (LPG), et une pompe à carburant gazeux liquéfié.
