Abstract
A method for controlling the operation of an internal combustion engine based on dynamic engine stability (roughness) compares actual running data with an rpm-dependent but smooth reference signal to obtain a measure of the torque fluctuations of the engine. This measure is fed to a final control element which adjusts the ignition timing angle of the engine alone or in addition to the adjustment of other engine parameters, such as the fuel-air ratio and/or the exhaust gas recycle rate.
