ABSTRACT:
The invention is directed to a control system for an internal combustion engine with reference to air throughput, rotational speed and lambda. In this control system, a decoupling device is provided between open loop and closed loop control signals which act with different speeds. An ignition signal is influenced in dependence upon a lambda-dependent signal via at least one dead time member. In this way, phases having unfavorable opposing influence on control branches of different reaction durations are reduced.
