A system is provided for controlling a fuel-metering device, for a diesel engine. First means generate a first signal for triggering a first actuating means (115) for establishing the start of pump delivery and the end of delivery. Second means generate a second signal for triggering a second actuating means (125) for establishing the delivery rate. In this case, a signal characterizing the start of pump delivery is taken into consideration by the second means.

System for controlling a fuel-metering device

A method and a device for the open-loop and/or closed-loop control of a final controlling element, in particular for influencing the fuel injected into an internal combustion engine, are described. A system deviation is defined starting from a setpoint and an actual value. On the basis of the system deviation, a loop controller specifies a manipulated variable to be received by the final controlling element. If the system deviation lies outside of a range defined by at least two values, a maximum value is specified for the manipulated variable.

Method and device for the open-loop and/or closed loop control of a

A device and a method for controlling an internal combustion engine, in particular a diesel internal combustion engine, having at least one solenoid valve, are described. On the basis of a desired quantity of fuel, an actuation period is determined for the solenoid valve and a signal for fixing the end of actuation is prescribed on the basis of the actuation period. Depending on the operating state of the internal combustion engine, the actuation period is determined either by means of a pump characteristic table or the desired quantity of fuel is used directly as the actuation period. Moreover, depending on the operating state of the internal combustion engine, either an uncorrected or a corrected signal is used for fixing the end of actuation.

Method and device for controlling an internal combustion engine

A method and apparatus for controlling a solenoid-valve-controlled fuel-metering system, especially for a diesel internal combustion engine, provide an electronic control device, which calculates a starting time and/or a stopping time for a solenoid valve based upon at least one of an injection start variable and a feed duration variable. An angle variable is calculated based upon a time variable, taking into consideration at least one of an instantaneous rotational speed and a correction angle.
