Abstract
(DE)
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Betriebscharakteristik einer Einspritzvorrichtung (30) eines Verbrennungsmotors (1), welcher durch einen Turbolader (4) aufgeladen ist, zu ermitteln. Dazu umfasst das Verfahren die Verfahrensschritte: A) Vornehmen einer Testeinspritzung von Kraftstoff in einen Zylinder (51, 52, 53, 54) des Verbrennungsmotors mittels des Einspritzsystems (30); B) Ermitteln eines Betriebsparameters des Turboladers (40); C) Ermitteln einer Betriebscharakteristik des Einspritzsystems (30) anhand des ermittelten Betriebsparameters des Turboladers (40).
(EN)
The invention relates to a method and a device for determining an operating characteristic of an injection system. The aim of the invention is to determine an operating characteristic (30) of an internal combustion engine (1) that is charged by a turbocharger (4). For this purpose, the method comprises the following steps: A) carrying out a pilot injection of fuel into a cylinder (51, 52, 53, 54) of the internal combustion engine using the injection system (30); B) determining an operating parameter of the turbocharger (40); C) determining an operating characteristic of the injection system (30) using the operating parameter of the turbocharger (40) previously determined.
