  • Publication number: 20090078241
    Abstract: The invention relates to a method for adjusting a displacement pump that has a variable volume flow rate in an internal combustion engine. Said method comprises the following steps: the displacement pump is driven; the fluid is conveyed to the consumption points in the internal combustion engine; at least one characteristic value is determined from the exhaust gas flow of the internal combustion engine; said characteristic value is forwarded to a control device as an actual value signal; the actual value signal is compared to a given target value; a control signal is preprocessed from the deviation between the actual value signal and the target value; the control signal is fed to an actuator; the volume flow rate of the displacement pump is modified by means of the actuator in accordance with the control signal; the steps of the method are repeated until the actual value signal is identical to the target value.
