Definitions

  • the invention relates to a method according to the genus Claim 1 from. Such a procedure is used at Subject of DE-A1-195 34 050 applied. There the Fact taken into account that high pressure accumulator leaks can be and the escaping fuel at the leaks can cause high damage. Around the damage should be limited if the leak occurs Appropriate protective measures are proposed there.
  • the memory pressure in High-pressure fuel storage can be increased without significant loss of drive power and Reinstate an operation with higher Performance requirement on the internal combustion engine this pressure can be reduced to a lower limit without that a subsequent delivery of high pressure fuel in the Fuel in the high-pressure fuel storage on the part of High pressure fuel pump is required.
  • the method is used in a fuel injection system such as it is shown in the figure is executed.
  • There is one Fuel tank 1 is provided, from which a Suction line 2 a high pressure fuel pump 3 fuel sucked in and via a pressure line 4 under high pressure in promotes a high-pressure fuel reservoir 6.
  • a Pressure control device 10 driven, e.g. such that about an adjustable valve which in a relief line 11 of the high-pressure fuel reservoir 6 is arranged excess fuel is returned to the tank becomes.
  • it can also affect the output the high pressure pump 3 can be intervened in which at a Design as a piston pump the effective delivery stroke of this Piston pump is adjusted or by the fuel supply to this high pressure pump from the control device 9 is controlled.
  • Control device 9 electrically controlled.
  • Control solenoid valves or piezo valves provided according to the requirements, for example from speed and load can be controlled.
  • the control device detects thereby operating parameters of the internal combustion engine and the Requirements for this internal combustion engine in relation to the torque to be output. These are, for example Parameter speed, an angular position transmitter, which the Torque request or load requirement of an actuated Control element detects the intake manifold pressure or boost pressure or the measurement result of an air flow meter, which the Air volume supplied to combustion chambers recorded.
  • you can other parameters such as cooling water temperature and Air temperature can be recorded and additional input signals according to the phase position of the crankshafts or Camshaft can be entered to exactly start injection and control the injection quantity.
  • the fuel high pressure accumulator in this Fuel injection system is on in normal operation Pressure levels kept> 500 bar. For security reasons however, the maximum allowable pressure in the High-pressure fuel storage much higher, for example at 1600 bar. If the internal combustion engine, e.g. a Motor vehicle drives, operated in overrun, so that High-pressure fuel accumulator little or no Fuel quantity removed for injection, if this push operation is defined so that due to Torques acting on the outside of the internal combustion engine in the sense of a speed increase on the injection quantity related speed is exceeded. The special case is given if e.g. one entered via an accelerator pedal Torque request to the default value of idling is withdrawn and the internal combustion engine due to the external forces continue to be above Idle engine speed remains.
  • the internal combustion engine e.g. a Motor vehicle drives
  • crankshaft of the internal combustion engine serve or from the on-board hassle of the internal combustion engine powered motor 26 of an electrically switchable Coupling 27 is coupled to the high-pressure fuel pump.
