ABSTRACT:
A system and method for controlling ignition timing for an internal combustion engine having cylinder bank rows are disclosed in which the ignition timings for the cylinders belonging to one of the cylinder banks determined according to engine load and engine revolution speed and are corrected according to differences in the ignition timings for the cylinders of both cylinder bank rows so as to eliminate variations in the ignition timings between each cylinder bank row. The crank angle sensor of the ignition timing control system is installed on at least one camshaft for either exhaust or suction valves on an overhead cam at one of the cylinders belonging to either of the cylinder bank rows.
