Abstract

Es wird ein Verfahren und eine Vorrichtung zur Steuerung einer Brennkraftmaschine mit Hochdruckeinspritzung, insbesondere für eine Brennkraftmaschine mit einem Common-Rails-System beschrieben. Der Kraftstoff wird von wenigstens einer Pumpe von einem Niederdruckbereich in einen Hochdruckbereich gefördert. Der Kraftstoffdruck wird im Hochdruckbereich mit einem Drucksensor erfaßt und mit einem Mittel zur Druckregelung geregelt. Bei einem Defekt im Bereich der Druckregelung wird der Kraftstoffdruck durch Beeinflussung des Kraftstoffflusses im Niederdruckbereich gesteuert.

Figure 00000001
A method and a device for controlling an internal combustion engine with high-pressure injection, in particular for an internal combustion engine with a common-rail system, are described. The fuel is delivered by at least one pump from a low pressure area to a high pressure area. The fuel pressure is detected in the high pressure range with a pressure sensor and regulated with a pressure control device. If there is a defect in the pressure control area, the fuel pressure is controlled by influencing the fuel flow in the low pressure area.
