ABSTRACT:
A method for determining a point in time of a start of combustion in a cylinder of an internal combustion engine includes: providing a base compression pressure model which gives a curve of a compression pressure in the cylinder as a function of the operating point; adjusting the base compression pressure model using measured cylinder pressures of at least one operating state of the internal combustion engine at points in time at which no combustion is taking place in the cylinder, in order to obtain an adjusted compression pressure model; and determining a point in time of a start of combustion with the aid of a pressure curve determined by the adjusted compression pressure model.
