Abstract

A method for operating an internal combustion engine, particularly of a motor vehicle. The internal combustion engine has a combustion chamber and an injection valve by which fuel is able to be supplied to the combustion chamber, directly or via an intake manifold. In the method, a maximum combustion chamber pressure and a signal for a start of the injection of fuel is determined, and the signal for the start of injection is influenced as a function of the maximum combustion chamber pressure. A signal for an injection duration of fuel is determined and influenced as a function of the maximum combustion chamber pressure.
