Title: Method and device for the transient operation of an internal combustion engine, in particular for a motor vehicle

Abstract: Method and device for operating an internal combustion engine for a motor vehicle, in which fuel is delivered under pressure by a delivery pump to a pressure chamber. The pressure acting upon the fuel in the pressure chamber is measured, and the fuel is injected by an injection valve directly into a combustion chamber of the internal combustion engine from the pressure chamber as a function of the measured pressure acting upon the fuel. When varying the working point of the internal combustion engine with regard to the pressure acting upon the fuel, it must be possible to control injection as accurately as possible even within the transient range, thus providing a sufficiently comfortable driving performance even within the transient ranges. This is achieved, in particular, in that the actual pressure acting upon the fuel is computed within the transient range and the working point of the internal combustion engine is adjusted correspondingly to this pressure.
