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.

Method for adapting a common-rail injection system of an internal combustion engine

A method for operating a valve, in particular a fuel injector of an internal combustion engine of a motor vehicle, in which an auxiliary variable is obtained as a function of at least one electrical operating variable of an electromagnetic actuator driving a component of the valve, in particular a valve needle, and in which the auxiliary variable is checked for the presence of a predefinable characteristic. A reference variable which characterizes the operating behavior of the electromagnetic actuator is ascertained, the auxiliary variable is modified as a function of the reference variable to obtain a modified auxiliary variable, and the modified auxiliary variable is checked for the presence of the predefinable characteristic.

A method and a device for controlling a fuel metering system are described. The fuel metering system includes at least one injector for injecting fuel into an internal combustion engine. An electric current value is applied to the at least one injector, and a rail pressure value is determined based on the electric current value.

In a method and a device for testing for leakage in a fuel injection valve of an internal combustion engine, a temperature quantity is determined that characterizes the temperature of at least a part of the fuel injection valve. On the basis of this temperature quantity, the presence of a leak is inferred.

A method and device for switching an inductor are described. A first terminal of the inductor may be connected to ground via a first switching device. A second terminal of the inductor is always connected to a voltage power supply. A second inductor may be connected to ground via a second switching device. The energy released in the second inductor when the current flow is interrupted is used to switch the first inductor.

Method and device for switching an inductor

A process and a device for controlling a movement of an armature of an electromagnetic switching element having an exciter coil. A first setpoint for the current can be defined after a first time. A second setpoint for the current can be defined after a second time. The second setpoint is smaller than the first setpoint. The second time also occurs before a third time at which the armature has reached its end position.
