ABSTRACT:
An engine ignition control apparatus for controlling ignition of a multi-cylinder, 4-cycle engine includes dual ignition coils for controlling ignition timing of the respective cylinders during engine operation. The engine ignition control apparatus includes a stroke determination unit for determining a stroke based on crank pulses and on an output signal of an intake pressure sensor. The engine ignition control apparatus also includes an ignition map allocation unit for allocating ignition maps to the respective cylinders of two ignition systems, each having a pair of cylinders with a same phase, before the stroke determination. The ignition map allocation unit also allocates ignition maps independently to each of the respective cylinders after the stroke determination. The engine ignition control apparatus also includes an ignition timing calculation unit for calculating ignition timing of the respective ignition coils based on the ignition maps allocated to the respective cylinders.
