Definitions

  • the objective of the present invention is to achieve a fuel system for a combustion engine which reduces the risk of operational disruptions caused by impurities in the fuel.
  • Another objective is to achieve a fuel system for a combustion engine which prevents that the person who replaces the filter comes into direct contact with fuel.
  • the pre-filter comprises a fine mesh water-separating filter element.
  • a valve is arranged downstream of the transfer pump and downstream of the pre-filter.
  • the valve has an inlet connected with the transfer pump, a first outlet connected with the first fuel pipe and a second outlet connected with the second fuel pipe, so that the transfer pump is connected with the first fuel pipe when the valve is arranged in a first position, and so that the transfer pump is connected with the second fuel pipe when the valve is arranged in a second position.
  • the first fuel tank may be bypassed and the transfer pump may feed fuel from the second fuel tank to the second fuel pipe, downstream of the first fuel tank and the main feed pump, and further to the combustion engine.

Abstract

La présente invention concerne un système de carburation (4) pour un moteur à combustion (2) comprenant un premier réservoir de carburant (20), un second réservoir de carburant (22), un premier tuyau de carburant (36) agencé en connexion avec le premier réservoir de carburant (20) et le second réservoir de carburant (22), un second tuyau de carburant (40) agencé en connexion avec le premier réservoir de carburant (20), deux pompes à carburant dont l'une est une pompe d'alimentation principale (26) et l'autre est une pompe de transfert (28). La pompe d'alimentation principale (26) est agencée pour amener le carburant du premier réservoir de carburant (20) à travers le second tuyau de carburant (40) et la pompe de transfert (28) est agencée pour amener le carburant du second réservoir de carburant (22) au premier réservoir de carburant (20) via le premier tuyau de carburant (36). Un premier moteur électrique (M1) est agencé pour entraîner la pompe de transfert (28) et un second moteur électrique (M2) est agencé pour entraîner la pompe d'alimentation principale (26). Un pré-filtre (30) est agencé en aval de la pompe de transfert (28) et un filtre à carburant principal (12) est agencé en aval de la pompe d'alimentation principale (26). Au moins une des pompes à carburant (26, 28) peut être redirigée de sorte que la direction du flux traversant au moins un des filtres à carburant (12, 30) peut être inversée. Le système de carburation empêche le carburant non filtré de contourner le filtre à carburant du fait d'un remplacement de l'élément de filtre dans un filtre à carburant. La présente invention concerne également un procédé de remplacement de filtre dans un système de carburation (4) empêchant l'amenée de carburant non filtré au moteur à combustion. Cela rend plus sûr le fonctionnement du moteur à combustion (2) et d'un véhicule (1) équipé d'un tel système de carburation.
