ABSTRACT:
An auxiliary revolution sensor (16) is disposed for detecting a reference position signal (16a) of each cylinders. A computer (3) outputs an auxiliary reference cylinder signal (3d) by the reference position signal (16a). A pseudo reference position signal generator (12, 13, 14, 15) generates a pseudo reference position signal (15a) by the auxiliary reference cylinder signal (3d). An electronic distributor (5) outputs ignition signals (6) to ignitors (6-11) by outputting signals of the pseudo reference position signal generator and the computer, when a revolution sensor (1) is out of order.
