ABSTRACT:
A method is proposed for the closed-loop control of the composition of the operational mixture furnished an internal combustion engine, in which the location of the peak combustion chamber pressure is ascertained relative to top dead center during sequential work cycles and a control signal is formed from the fluctuations in the occurrance of the peak combustion chamber pressure from top dead center, by means of which control signal a permissible extent of fluctuation is established by means of influencing components of the operational mixture or the ignition angle.
