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.
