Abstract

Das Verfahren zur Regelung einer Verbrennungsmaschine mit einer gasdynamischen Druckwellenmaschine, wobei die gasdynamische Druckwellenmaschine (30) ein drehbares Gehäuse (58), um die Prozessabstimmung über den ganzen Kennfeldbereich der Verbrennungsmaschine (33) abzustimmen, und eine variable Breiteverstellung des Hochdruck-Abgaskanal (31) enthält folgende Punkte, wobei in jedem Kennfeldbereich eine bestimmte Reihenfolge der Regelung eingehalten wird, wobei bei einem positiven Lastsprung

  • die Drehzahl und das Gehäuse der gasdynamischen Druckwellenmaschine mit geeigneten Mitteln auf die im Kennfeld abgespeicherte optimale Position eingestellt werden,
  • die variable Breiteverstellung des Hochdruck-Abgaskanals auf den aus dem Kennfeld benötigten Ladedruck eingeregelt wird; und
bei negativem Lastsprung
  • die Drehzahl und das Gehäuse der gasdynamischen Druckwellenmaschine mit geeigneten Mitteln auf die im Kennfeld abgespeicherte optimale Position eingestellt werden und
  • die variable Breiteverstellung des Hochdruck-Abgaskanals möglichst weit geöffnet wird, um die Druckdifferenz von Hochdruckladeluft zu Hochdruckabgas möglichst gering zu halten.
The method for controlling an internal combustion engine with a gas-dynamic pressure wave machine, wherein the gas-dynamic pressure wave machine (30) a rotatable housing (58) to adjust the process tuning over the entire map range of the internal combustion engine (33), and a variable width adjustment of the high-pressure exhaust passage (31) contains the following points, wherein in each map area a certain order of control is met, with a positive load step
  • the speed and the housing of the gas-dynamic pressure wave machine are adjusted by suitable means to the optimum position stored in the map,
  • the variable width adjustment of the high-pressure exhaust gas channel is adjusted to the required from the map boost pressure; and
with a negative load jump
  • the speed and the housing of the gas-dynamic pressure wave machine are adjusted by suitable means to the optimum position stored in the map and
  • the variable width adjustment of the high-pressure exhaust gas passage is opened as far as possible in order to minimize the pressure difference between high-pressure charge air and high-pressure exhaust gas.

Eine solche Regelungsfolge schützt die gasdynamische Druckwellenmaschine vor Beschädigungen und optimiert den Betrieb und die Leistung der Verbrennungsmaschine.
