Abstract:
1. A method of determining a composition of a fuel mixture consisting of a first fuel and at least a second fuel for operating a self-igniting combustion engine with at least one sensor that is determining a course of combustion in at least one cylinder of the combustion engine, the method comprising: creating a measure for stability of the combustion process from a parameter that characterizes a combustion process in at least one cylinder of the combustion engine, wherein the determination of the composition of the fuel mixture takes place from the measure for the stability of the combustion process; adjusting operating parameters of the combustion engines such that the measure for the stability of the combustion process does not exceed a predefined threshold value for the stability of the combustion process; and providing one or more of the following for complying with the predefined threshold value:
