ABSTRACT:
A method and device control a volumetric flow in a common rail injection system of an internal combustion engine by producing a rail pressure with a high pressure pump, setting the rail pressure with a high pressure control valve and determining the volumetric flow by a valve position of a volumetric flow control valve controlled by a precontrol characteristic field and a two-dimensional adaptation characteristic field having adaptation values for the valve position predefined as a function of two operating parameters of the engine. This overcomes the problem in current common rail injection systems of the adapted valve position of the volumetric flow control valve often being subject to error, for instance because the valve position is controlled as a function of the rail pressure only using a one-dimensional adaptation characteristic field. This can lead to unwanted ambiguities, which can result in injecting fuel in incorrect quantities.
