Abstract (en)

[origin: WO2012065788A1] The invention relates to a method for operating a combustion engine in the HCCI mode, having the following steps: a) sensing (S1) of a profile of a measured value of a variable in a combustion chamber of a cylinder (3) of the combustion engine (2); b) acquisition (S2) of one or more combustion features (SOC, MFB10%, MFB50%, MFB90%, Q10%, Q50%, Q90%) of a combustion process in a first combustion cycle based on the measured profile of the measured variable; c) determination (S3), in particular modelling, of a first value of a state variable at a defined time after the first combustion cycle and before a second subsequent combustion cycle based on the acquired one or more combustion features (SOC, MFB10%, MFB50%, MFB90%, Q10%, Q50%, Q90%); d) determination (S4) of desired setpoint values of one or more combustion features of a combustion process in the second subsequent combustion cycle; e) determination (S5), in particular modelling, of a second value of the state variable at the defined time on the basis of the setpoint values of the one or more combustion features (SOC, MFB10%, MFB50%, MFB90%, Q10%, Q50%, Q90%) of the second combustion cycle; and f) actuation (S8) of the combustion engine (2) starting from the defined time as a function of the first value of the state variable and the second value of the state variable.
