摘要： The invention concerns a procedure for determining the composition of a fuel mixture from a first fuel and a second fuel or for determining the quality of a fuel for operating a combustion engine with at least one cylinder pressure sensor in at least one cylinder of the combustion engine for determining the pressure history during a combustion process and a cylinder pressure based motor regulation for regulating the load and the combustion situation of the combustion engine. It is thereby provided that the determination of the composition of the fuel mixture or the quality of the fuel takes place with the aid of regulator information of the cylinder-pressure-based motor regulation. The procedure enables the continuing determination of the composition of the fuel mixture and the quality of the fuel at cylinder-pressure-based motor regulations without additional components as for example an ethanol sensor.
