Abstract

The invention relates to a method for detecting and processing the rotation speed of a multicylinder combustion engine. The rotation speed values of individual equal intervals of each work cycle of the combustion engine are stored in separate successive storage registers, compared with the corresponding values of the intervals of the following work cycle and processed for control purposes. <IMAGE>
