  • Patent number: 11506163
    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.

  • Patent number: 11506162
    Abstract: A fuel system includes a fuel injector having a split check assembly with a control piece, an outlet piece, and a check sleeve. A trapped volume is formed between the control piece and the outlet piece within the check sleeve, to hydraulically couple the control piece to the outlet piece. A starting rate shape clearance fluidly connects the trapped volume to a fuel cavity and is formed between the check sleeve and one of the control piece or outlet piece received therein, and modulates a starting rate shape of fuel injection from the fuel injector. Related methodology is disclosed.

  • Patent number: 8091346
    Abstract: A method for regenerating a filtering device is disclosed. The method may include creating a flow of exhaust with a power source and providing air to a combustion device configured to heat the flow of exhaust. The method may also include determining if a parameter is above a threshold. The parameter may be indicative of an amount of air provided to the combustion device. The method may further include modifying an operating condition of the power source if the parameter is above the threshold, where modifying the operating condition affects the parameter.

  • Patent number: 8006482
    Abstract: A fluid injector for use in an exhaust treatment system is disclosed. The fluid injector may have a nozzle portion, a heater associated with the nozzle portion, and a controller in communication with the heater. The controller may be configured to recognize a condition triggering a purge event of the fluid injector. The controller may also be configured to activate the heater to purge the fluid injector in response to the recognized condition.
