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.

摘要： A method for operating an internal combustion engine in which a speed-based feature of the internal combustion engine, which is correlated with an indicated mean effective pressure of the fuel, is determined during the warm-up of the internal combustion engine and an ideal fuel quantity, which is to be injected into at least one combustion chamber of the internal combustion engine during the warm-up, is ascertained therefrom.
