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 is presented for compensating for combustion chamber-specific actual values of a parameter, which characterizes combustions, between a plurality of combustion chambers of an Otto engine (10) operated with homogeneous filling of the combustion chambers and homogeneous charge compression ignition, said Otto engine (10) operating with a direct fuel injection and a variable valve drive, wherein the combustion chamber-specific actual values are formed as a function of signals (S—40; S—42) of combustion chamber-specific sensors (40; 42) and wherein deviations of the combustion chamber-specific actual values from a set value are processed to manipulated variables, with which a valve lift of a gas exchange valve (28) of a combustion chamber (12) is changed. The method distinguishes itself by the fact that a characteristic (pmi_ZV), in which combustion chamber-specific charge change losses are reflected, is formed as a variable characterizing combustions and by the fact that a valve lift of an intake valve (28) of the combustion chamber (12) is changed as a manipulated variable. Independent claims relate in each case to a control unit, a computer program and a computer program product.
