PURPOSE:To reduce program load in a rotary engine by alternatively changing over current supply ignition timing controls at the leading and trailing sides with a crank angle. CONSTITUTION:CPU1 renews a Ne counter by interruption activated with the crank angle signal Ne to judge which ignition signal of two systems is in timing for setting current supply starting period to a programmable timer in the present Ne position. If YES, time from the present Ne position to current supply starting is set. for example, in Ne counter =n position the leading current supply period is judged. If YES, time up to that period is set to a timer L and in n+1 position to a timer T. That is, in a certain Ne timing, only one of leading and trailing current supply control is carried out alternatively. |
