Abstract
A method for controlling an internal combustion engine with a common-rail system, in which a fuel quantity is computed from a measured fuel pressure distribution and in which the computed fuel quantity is set as the controlling value for controlling an injection. The fuel quantity is computed by measuring the pressure distribution (pE) of an individual accumulator, reproducing a modeled pressure distribution (pEMOD) according to the measured pressure distribution (pE) using a hydraulic model, and computing the fuel quantity from the hydraulic model.
