20090063027 | Fuel or Additive Pump Controller - Fuel or additive pump controller is integrated to a fuel system control unit (FSCU), and communicates with an engine control unit (ECU) and/or crash sensors through communication means. The controller comprises means for generating a pump control signal. Said means use data on crash occurrence from the ECU or from said crash sensors for turning off the pump or limiting the pump speed in case of crash. | 03-05-2009 |
20090099795 | LEAK DETECTION METHOD AND ASSOCIATED VALVE AND FUEL SYSTEM - Method of detecting a leak in a fuel system comprising a fuel tank and an orifice with a controlled section between the tank and the atmosphere, according to which

20090314072 | Method and system for detecting a cap off situation on the fuel tank of a vehicle - Method for detecting a cap off situation on the fuel tank of a combustion engine vehicle having a fill pipe head located under a fuel fill door, according to which a cap off test is run when the engine is started again after having been switched off and when a door switch indicates that the fuel fill door has been opened. | 12-24-2009 |
20110309166 | Electromagnetically Controlled Injector Having Flux Bridge And Flux Break - An injector for injecting a reagent includes an axially translatable valve member positioned within a housing. An electromagnet is positioned within the housing and includes a cylindrically-shaped coil of wire. The valve member moves between a seated position and an unseated position in response to energizing the electromagnet. A flux sleeve passes through the coil and includes two magnetic portions interconnected by a non-magnetic portion. Each of the magnetic portions is aligned with transverse planes defined by the ends of the cylindrical coil. The non-magnetic portion is axially positioned between the transverse planes. | 12-22-2011 |
20120141331 | Reagent Tank Normalizing System - A reagent injection system for reducing emissions from an engine includes a reagent container. A heating element is positioned in a heat transfer relationship with reagent stored within the container. An interchange tube includes a first end in receipt of a recirculated liquid reagent and a second open end positioned in the container. The interchange tube includes a bleed-off tube branching off of the interchange tube between the first and second ends. A terminal end of the bleed-off tube is positioned within a vapor dome above a surface of the reagent. | 06-07-2012 |
20130299604 | Coaxial Flow Injector - An injector for injecting a reagent includes an axially translatable valve member positioned within a housing. An electromagnet is positioned within the housing and includes a coil of wire positioned proximate the valve member such that the valve member moves between a seated position and an unseated position relative to an orifice in response to energizing the electromagnet. A connector coupled to the housing includes an inlet tube concentrically aligned with and surrounding a return tube. The inlet tube is adapted to receive pressurized reagent from a source of reagent. The return tube is adapted to return reagent to the source. | 11-14-2013 |
20140070031 | REAGENT INJECTOR WITH CRIMPED PINTLE - An injector for injecting a reagent includes an electromagnet and an axially translatable valve member positioned within a housing. The valve member is moveable from a seated position to an unseated position in response to energizing the electromagnet. The valve member includes a hollow tube including a curled end having a reduced diameter sized to allow a ball to partially extend beyond the tube end but not pass through the tube. The tube includes an inwardly extending detent restricting the ball from movement within the tube. A pintle head is fixed to the tube and positioned proximate the electromagnet. | 03-13-2014 |
