Definitions

  • the invention relates to an arrangement with an injection pump of a diesel engine, the injection pump having a power control element and a shutdown element, the power control element also being controllable by a digital control device.
  • shut-off element also located on the injection pump is actuated.
  • the object of the present invention is to make it possible, in the event of a defect in the area of the control of the power control element of an injection pump, for the engine to continue to run at an uncritical speed.
  • the arrangement according to the invention is characterized in that the shut-off element can be controlled in a pulsating manner by the digital control device in such a way that a predetermined speed of the diesel engine is achieved.
  • a further development of the invention is that the digital control device and the shut-off element form a two-point controller. This makes it possible in a simple manner to maintain the specified speed value of the required accuracy.
  • a linear actuating behavior can also be achieved by using a suitable actuator and at a suitable clock frequency.
  • the shut-off element in connection with an assigned actuator can be designed so sluggishly that the speed results from the mean value of the pulses at a sufficiently high clock frequency.
  • the pulsating control of the shutdown element can be triggered by a defect in the control of the power control element.
  • the engine speed is automatically reduced to a defect within the system formed by the digital control device and the power control element reduced uncritical value.
  • the arrangement according to the invention can also be expanded such that the pulsating control of the shut-off element can be triggered when the permissible operating conditions are exceeded.
  • the engine power can be limited, e.g. B. on the maximum speed of the vehicle or maximum engine speed.
  • a further development is that a device for linking a signal emitted by the digital control device with another signal provided for switching off the diesel engine is arranged between an output of the digital control device provided for the switch-off element and the switch-off element. This means that the engine can be switched off at any time independently of the digital control device.
  • the invention allows numerous embodiments. One of them is shown schematically in the drawing and described below.
  • a digital control device 1 is connected to an actuator 2, which in a manner known per se from an electric motor with a downstream transmission can exist.
  • the actuator 2 is connected to the power control element 4 of an injection pump 5 of a diesel engine, not shown, via a linkage 3.
  • a setpoint value for the engine power is supplied to the digital control device by an accelerator pedal 6. Furthermore, the digital control device is connected to sensors 7, 8 for the speed n and the speed v.
  • the arrangement according to the invention can also be used to limit the engine speed or speed.
  • a correspondingly modified or supplemented program must be provided in the digital control device, so that the shut-off mechanism 10 is actuated not only in the event of a defect, but also in normal operating conditions when the permissible operating conditions, for example the permissible speed, are exceeded.
