Definitions

  • the invention relates to a method for controlling and regulating an internal combustion engine according to the preamble of claim 1.
  • the start of injection and the end of injection significantly determine the quality of the combustion and the composition of the exhaust gas. To comply with the legal limits, these two parameters are usually controlled by an electronic control unit.
  • an electronic control unit In practice occurs in an internal combustion engine with a common rail system, the problem that there is a time offset between the start of energization of the injector, the needle stroke of the injector and the actual injection start. The same applies to the end of injection.
  • the object of the invention is for an internal combustion engine with a common rail injection system including individual storage as in DE 43 44 190 A1 to design a test method for the injector.
  • the invention provides a method for control and regulation in which an injection end deviation is calculated from a desired injection end and the measured actual injection end and an injection start deviation from a desired injection start and the virtual actual injection start is determined. Thereafter, an injector is evaluated based on the injection end deviation and the start of injection deviation and the further control and regulation of the internal combustion engine is based on the injector evaluation.
  • an injection end tolerance band is selected and it is checked whether the injection end deviation lies within the injection end tolerance band.
  • a start of injection tolerance band is selected and also checked whether the injection start deviation is within the tolerance band. The selection of the respective tolerance band as well as its limit values takes place as a function of the operating state of the internal combustion engine.

Are these outside the respective Tolerance band, the injector is rated as faulty.
