PURPOSE:To prevent an incomplete ignition or a misfire from occurring with certainty, by installing an energizing start timing compensation device which receives the output of an acceleration detecting device and quickens the energizing start timing for an ignition device, while quickening the energizing start timing in time of acceleration. CONSTITUTION:In time of engine operation, a reference signal is generated by a reference signal generating device 6 which generates signals at every specified crank angle, and on the basis of this reference signal, ignition timing resting on an engine operating state, that is, energizing end timing to an ignition device 41 is calculated by an ingition timing calculation device 38. Moreover, on the basis of the said reference signal, energizing start timing to the ignition device 41 is calculated by another energizing start timing calculation device 39. And in conformity with the energizing start timing and its end timing, the ignition device 41 is driven. At this juncture, when engine acceleration is detected by an acceleration detecting device 4, it is compensated so as to quicken the energizing start timing by an energizing start timing compensation device 40. |
