| description | A method for metering fuel from a high pressure system, comprising at least one high pressure pump, one pressure accumulator and one high pressure injection valve, into an exhaust gas duct of an internal combustion engine in order to regenerate a nitrogen oxide storage catalyst (NSC) disposed in the exhaust gas duct, wherein a higher pressure of the fuel is generated by the electrically actuated high pressure pump, which discretely delivers fuel and has a constant stroke volume, wherein the fuel is supplied to the pressure accumulator comprising a pressure measuring device for determining the fuel pressure and wherein the fuel is injected into the exhaust gas duct via the downstream, electrically actuated high pressure injection valve. |
