Definitions

  • the invention relates to a method according to the preamble of the main claim and a device according to the preamble of claim 10. It is known to supply the fuel metering systems of an internal combustion engine from the tank with the fuel via special electric fuel pumps, the metering systems being carburettors of any shape and design or Injection systems can be; In the case of self-igniting internal combustion engines (diesel engines), mechanically driven injection pumps are usually provided, the injection quantity of fuel of which is determined via an interlocking device, which can operate hydraulically or magnetically, for example.
  • a sensible control distribution also ensures that in the event of a defect that occurs in the respective electric fuel pump, the second electric fuel pump is automatically switched over, since in this case - the defect can be detected by comparing the control path setpoint with the actual control path value - both electric fuel pumps are on delivery be switched.
  • the basic idea of the present invention is to assign the fuel metering or supply system of an internal combustion engine to two electric fuel pumps EKP1 and EKP2 that deliver the required fuel from the fuel tank and to control the operation of the two electric fuel pumps by observing peripheral operating conditions of the internal combustion engine from a central control device.
  • the two electric fuel pumps EKP1 and EKP2 supply in order to stay with the example adopted, an injection pump EP operated with an electronic diesel control EDC.
