Abstract
The invention relates to a method of damping abnormal vibrations or bucking of spark ignition engines by adjustment of the ignition angle, including simultaneous detection and temporary storage of a value representative of the effective or instantaneous load and, by comparing the load value against successive load values, establishing changes in the load, whereby such change in load, in case a predetermined threshold is exceeded, affects an adjustment of the effective ignition angle, with resetting of the ignition angle to the effective or characteristic field angle taking place as a function of the gradient of engine rotations.
