Method and device for controlling an ignition coil in an internal combustion engine incorporates an RPM-detector to record an IC engine RPM at a recording time point within a cylinder's ignition cycle

摘要

An RPM-detector records an IC engine RPM at a recording time point within a cylinder's ignition cycle. A specifying device defines a preset advance angle corresponding to the detected RPM, also a preset charging time corresponding to the detected RPM and a corresponding charging start angle. An ignition control value output device passes to the ignition coil the charging start angle, a charging time in a charging-time output mode and the advance angle in an advance angle output mode.
