  • Method and control unit for operating a valve
    Patent number: 9322356
    Abstract: In a method for operating a valve, e.g., a fuel injector of an internal combustion engine in a motor vehicle which is activated with the aid of an actuator, the actuator is activated using a control variable which has a predetermined control period. The control period is formed as a function of a setpoint value for a closing delay time of the valve which characterizes a time difference between an end of the control period and a closing point in time of the valve.

  • METHOD AND DEVICE FOR CONTROLLING AN INJECTION VALVE
    Publication number: 20140283793
    Abstract: An activation signal for activating a solenoid valve, in particular, a fuel injector of an internal combustion engine, has a pickup phase and a holding phase. The pickup phase has a comparatively high current and a maximally permissible duration, and the holding phase has a comparatively low current and a minimally permissible duration (MHD). The minimally permissible duration (MHD) of the holding phase is at least periodically dependent on a nominal total duration (GAD) of the activation signal.
