Patent number: 10786771Abstract: The fuel filter (1) contains a filter element (4) and an additive tank (13) in a housing (2, 3). The filter element is engaged against the removable cover (3) of the housing and has a filter medium (5) extending in an annular manner around an inner space (9). An additive release device (32) extends into this inner space (9) to distribute liquid additive from the tank (13) into a fuel circulation circuit for an internal combustion engine. The additive selectively flows into a sealed distribution channel (DC) of the device (32) depending on an open or closed configuration of an actuator component (62) associated with the distribution channel. The distribution channel (DC) opens into a fuel channel (52) of the cover (3) that has a larger cross-section than the distribution channel (DC).Type: GrantFiled: December 10, 2014Date of Patent: September 29, 2020Assignees: Sogefi Filtration France, Rhodia OperationsInventors: Jean-Jacques Falc'hon, Christophe Guillon, Guy Monsallier, Virginie Harle, Antoine Lacarriere

Patent number: 10583381Abstract: In a filter cartridge (CC) for a fuel filter, the filter element (4) and the additive module are connected and typically stacked so as to allow them to be integrally inserted into a filter housing. The substantially annular filter medium (5) delimits an inner space (9) into which at least one part (24) of the attachment end of the additive module can be engaged. The liquid additive is stored in a casing forming a tank (13) that is placed at a fuel pressure and delimits an internal volume (V2) that can be varied so as to maintain an identical pressure between the liquid additive and the fuel at the periphery (V3) of the tank (13). The additive module has an external connection (28) with a liquid additive outlet pipe (12a), said external connection (28) including sealing means (37, 38) for automatically closing the outlet pipe in a fluidtight manner when the external connection is in a disengaged state.Type: GrantFiled: December 10, 2014Date of Patent: March 10, 2020Assignees: Sogefi Filtration France, Rhodia OperationsInventors: Jean-Jacques Falc'hon, Christophe Guillon, Guy Monsallier, Virginie Harle, Antoine Lacarriere

Patent number: 9677969Abstract: The invention relates to a method for diagnosing the malfunctioning of a device for adding an additive into a fuel for a vehicle comprising an internal combustion engine, said method including: a step of analyzing the fuel in order to determine a variation in the amount of additive in the fuel; a step of comparing the variation in the amount of additive, measured during the previous step, with a theoretical variation in said amount; a step of sending information when the difference between the measured variation and the theoretical variation exceeds a set value. The invention also relates to a system for adding an additive into fuel and for diagnosis for a vehicle comprising an internal combustion engine, which is intended for implementing said method.Type: GrantFiled: January 4, 2013Date of Patent: June 13, 2017Assignees: Rhodia Operations, Filtrauto SAInventors: Virginie Harle, Michael Lallemand, Thierry Seguelong, Guy Monsallier
