The invention provides a process and apparatus for controlling combustion in an Otto combustion engine in which the control variables that control combustion are determined for a particular power cycle as a function of the detected combustion course of a preceding power cycle. According to the invention, a desired burn-through function value for a particular power cycle is precalculated based on values of pertaining influence factors detected in a preceding power cycle, to determine an actual burn-through function value of the particular power cycle in real time. The desired burn-through function is compared with the actual burn-through function and actualized values for the burn-through function influence factors are determined. These factors are used to determine the control variable values for a subsequent power cycle.

[ What is claimed is:] [1.] Process for controlling combustion in an Otto combustion engine, wherein control variables for controlling a combustion course for a particular power cycle are determined using a control device, as a function of a detected combustion course of a preceding power cycle, said process comprising the steps of:precalculating a desired value for a burn-through function for a particular power cycle during its charge cycle phase, based on actual values of burn-through function influence factors detected during a preceding power cycle, by integrating the combustion course during the preceding power cycle with respect to either time or crank angle;determining in real time an actual burn-through function value during a high-pressure phase of a particular power cycle using a neuronal network which receives as inputs one or several quantities representative of the combustion course;comparing the precalculated desired burn-through function value with the actual burn-through function value; andbased on a result of said comparing, controlling combustion in the Otto combustion engine based on determined actualized values for the burn-through function influence factors on which a combustion-controlling determination of control variable values for a subsequent power cycle is based.
