摘要：PURPOSE:To reduce the number of circuits and thereby promote low-unit cost of production, by installing a free-run counter stepping up a minute turning angle change in an output shaft, while controlling an ignition coil in comparison with control data, and performing this data comparison at every specified rotation. CONSTITUTION:A free-run counter 10 stepping up an angle signal in succession and energization and ignition control data are compensated on the basis of data being counted at the generation timing of a reference signal to be generated at the specified rotation position of an engine output shaft. Likewise, these energization and ignition control data are compensated just before the control time. After generation of the reference signal, the first compensation takes palce and the energization and ignition are controlled by means of comparison with the counted data but at a time other than this, the subsequent compensation takes place whereby control is performed likewise. With this constitution, the control is performable with only use of each one of counters and comparator circuits, thus low-unit cost of production comes to fruition.
