Abstract (en)
[origin: WO9007057A1] Process for controlling ignition in an internal combustion engine, in which the ignition of a spark plug is determined by an ignition coil associated with each spark plug, and by a first counter which, when a reference mark independent of the angle is reached, counts up or down from a predetermined value, by means of a timing signal dependent on the angle, in order to trigger the ignition of a spark plug of the internal combustion engine. The spark plug to be ignited is determined by a cylinder identification device. The process is characterized in that the moment at which charging of all ignition coils of the internal combustion engine begins is determined by means of a single additional counter whose tally varies in function of the angle-dependent timing signal and to which a starting value corresponding to the interval until the start of charging of the next coil is pre-assigned. Hence, while the first counter triggers the ignition process, the second counter determines the moment at which the charging process of an ignition coil begins.
