Abstract

Verfahren zum Betrieb einer Verbrennungskraftmaschine (2), wobei die Verbrennungskraftmaschine (2) aufweist: zumindest einen Brennraum (3), in dem ein Brennstoff mit Umgebungsluft zumindest teilweise verbrannt wird, einen Abgasstrang (6), der an eine Auslassseite (7b) des zumindest einen Brennraums (3) fluidkommunizierend gekoppelt ist, wobei als Brennstoff für die Verbrennungskraftmaschine (2) Wasserstoff verwendet wird, wobei die Verbrennungskraftmaschine (2) weiterhin zumindest einen Stickoxid-Speicherkatalysator (13) aufweist und ein aus dem zumindest einen Brennraum (3) in den Abgasstrang (6) entladenes Abgas zumindest teilweise, vorzugsweise vollständig, den zumindest einen Stickoxid-Speicherkatalysator (13) durchströmt, wobei in dem zumindest einen Brennraum (3) in einem ersten Betriebszustand ein mageres Luft/Wasserstoff-Gemisch verbrannt wird, wobei in einem zweiten Betriebszustand der Stickoxid-Speicherkatalysator (13) regeneriert wird. Um die Verbrennungskraftmaschine in einfacher Weise als Niedrigstemissions-System zu betreiben wird in dem zweiten Betriebszustand in dem zumindest einen Brennraum (3) ein fettes Luft/Wasserstoff-Gemisch verbrannt.
