Method for determining size characterizing injection rate of injectors for injection of fuel in combustion chamber of internal-combustion engine under high pressure, involves blocking rail pressure produced by variation of injection samples

The method involves blocking a rail pressure produced by variation of the injection samples. The injected injection rate or rate difference is closed from the temporally process of the rail pressure due to the variation of the injection samples. Independent claims are included for the following: (1)...

description	The method involves blocking a rail pressure produced by variation of the injection samples. The injected injection rate or rate difference is closed from the temporally process of the rail pressure due to the variation of the injection samples. Independent claims are included for the following: (1) a computer program; and (2) a computer program product with program code. Es wird ein Verfahren zur Bestimmung wenigstens einer die Einspritzmenge charakterisierenden Größe von Injektoren (131) zur Einspritzung von Kraftstoff in einen Brennraum einer Brennkraftmaschine unter hohem Druck, durch folgende Schritte bereitgestellt: - Es wird eine gezielte Störung des Raildrucks durch Variation der Einspritzvorgröße hervorgerufen, - der Raildruck wird erfasst und - es wird aus dem zeitlichen Verlauf des Raildrucks auf die aufgrund der Variation der Einspritzvorgänge eingespritzte Einspritzmenge bzw. Mengendifferenz geschlossen.
