    摘要： 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 a) the controlled section is set to a value A1 at a time T1 and a pressure differential Δp1 between the inside of the tank and the atmosphere is measured at least after an interval of time ΔT from T1, for a constant fuel flow out of the tank; b) the controlled section is set to a value A2 at a time T2 and a pressure differential Δp2 between the inside of the tank and the atmosphere is measured at least after the same interval of time ΔT from T2, for the same constant fuel flow; c) a ratio of the pressure differentials Δp1 and Δp2 is computed and is compared to a reference pressure differential ratio APL obtained with the same fuel system but comprising a calibrated leak.

    摘要： 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.

    摘要： 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.

    摘要： 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.
