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.
