  • Method and unit for operating a fuel metering system in an internal combustion engine
    Patent number: 10174668
    Abstract: A method and a unit for operating or for the operation of a fuel metering system of an internal combustion engine, in particular in a motor vehicle, and it being provided, in particular, that at least one operating variable of the internal combustion engine is detected, a dynamic operating state of the internal combustion engine is detected based on the at least one detected operating variable, and a dynamic correction to the fuel metering system of the internal combustion engine is carried out for a detected dynamic operating state of the internal combustion engine, taking into account the efficiency of an NOx exhaust gas aftertreatment system.
    Type: Grant
    Filed: October 29, 2015
    Date of Patent: January 8, 2019
    Assignee: ROBERT BOSCH GMBH
    Inventors: Lars Engelfried, Michael Bachner, Rolf-Dieter Koch
  • Method for adapting a common-rail injection system of an internal combustion engine
    Patent number: 9803579
    Abstract: In a method for adapting at least one injector of an injection system, in particular of a common-rail injection system of an internal combustion engine of a motor vehicle, where injections take place based on a characteristics map with at least two input variables and at least one output variable, a transition is carried out into a learning mode in which only discrete values are permitted for one of the at least two input variables of the characteristics map.
