Patent number: 9702782Abstract: It is proposed a method for detecting a leak in a fuel system of a combustion engine comprising a fuel tank. The method is such that it comprises the steps of: obtaining a first set of data comprising at least a pressure data measured in the fuel system at a first time; adding energy to fluids contained in the fuel system, said energy being produced or wasted by means already present on board the vehicle for other purposes; obtaining a second set of data comprising at least a pressure data measured in the fuel system at a second time; determining the presence/absence of a leak in said fuel system by calculating a predetermined function on the basis of said first and second sets of data.Type: GrantFiled: May 3, 2013Date of Patent: July 11, 2017Assignee: Inergy Automotive Systems Research (Societe Anonym)Inventors: Bjorn Criel, Antoine Chaussinand, David Hill

Publication number: 20150076147Abstract: The invention is based on the insight that a filling system obtained by combining a “Kruse” compatible threaded socket and an annular magnet as required for the operation of the “Elaflex” nozzle, will exhibit air exchange problems related to the difference in the positioning of the respective air intake openings of the “Kruse” bottle and the “Elaflex” nozzle. More particularly, the invention is based on the insight that by judiciously providing a chamber in fluid communication with the volume of air or vapor in the tank, filling may be made possible with a “Kruse” bottle as well as with an “Elaflex” nozzle.Type: ApplicationFiled: November 19, 2014Publication date: March 19, 2015Applicant: INERGY AUTOMOTIVE SYSTEMS RESEARCH (Societe AnonymInventors: Laurent BUDZYK, Paul ELONG

Publication number: 20110290013Abstract: A capacitive probe comprises a first electrode, a second electrode, and a third electrode. A cap is positioned on a first end of the first electrode and a first end of the second electrode. A base is positioned on a second end of the first electrode, a second end of the second electrode, and a second end of the third electrode. A support is positioned on a first end of the third electrode and in contact with a surface of the second electrode. The electrodes can be coaxial cylinders or parallel plates. The gauge can be used with a system for measuring a quantity and quality of a liquid, more specifically, of an aqueous urea solution in the tank of an SCR system.Type: ApplicationFiled: February 9, 2010Publication date: December 1, 2011Applicant: INERGY AUTOMOTIVE SYSTEMS RESEARCH (Societe Anonym e)Inventors: Volodia Naydenoy, Laurent Morgana

Publication number: 20090260716Abstract: Plug system built into the top of a fuel tank filler pipe, comprising a plug with a locking device, a fuel flap able to occupy a position allowing access to the pipe and a position preventing access to the pipe, and a mechanical connection system able to transmit a movement from the flap to the locking device in such a way as to lock or unlock the plug. The mechanical connection system comprises components able to interact by part of a movement of one component being transmitted to another, adjacent component in such a way that only part of the movement of the flap can be transmitted to the locking device in order to lock or unlock the plug.Type: ApplicationFiled: May 15, 2007Publication date: October 22, 2009Applicant: INERGY AUTOMOTIVE SYSTEMS RESEARCH (Société AnonymInventors: Patrice Baudoux, Ambroise Zanini, Michele Dauzou Veuve Zanini
