  • Publication number: 20220186697
    Abstract: A fuel injector nozzle assembly includes a two-piece outlet check having a timing control piece and a rate control piece. A nozzle passage is formed between a nozzle body and a two-piece outlet check, and a sac cavity is formed by the rate control piece and the nozzle body and fluidly connects a through-hole in the rate control piece to nozzle outlets. A starting-flow clearance is formed by the rate control piece and the timing control piece, and is opened by moving the timing control piece relative to the rate control piece. Moving the rate control piece relative to the nozzle body opens a main-flow seat. The nozzle assembly provides a slow starting injection rate shape in a common rail or similar fuel system and improved controllability over minimum delivery quantities.

  • Publication number: 20220187186
    Abstract: A method for calibrating a contaminant detection device includes fluidly connecting the contaminant detection device in series to a test reservoir and a light-obscuration-type particle counter, pumping low-end, intermediate, and high-end test dust dilutions through the contaminant detection device and the particle counter until a particle count measured by the particle counter for each of the successive test dust dilutions stabilizes, and setting a low-end gain, an intermediate gain, and a high-end gain for the contaminant detection device based on the stabilized particle counts for each of the test dust dilutions using a first-sized test dust grade. A bubble counting gain of an aeration threshold for the device may be set according to a second test dust grade greater in size than the first-sized test dust grade, and associated with a voltage signal produced by the contaminate detection device indicative of the presence of an air bubble contained within the fluid during use of the fluid in heavy machinery.
