Abstract
Spark advance apparatus for an internal combustion engine utilizes an electronic counter circuit to count pulses generated at a rate proportional to engine speed and also utilizes a device energized by the counter circuit to control the charging time of the ignition coil. The counter circuit includes a first counter that is active until a first count is reached. Thereafter, a second counter of the counter circuit counts a predetermined number of pulses occurring at a frequency relates to a particular engine parameter. The device to control charging of the coil is activated at the end of the count by the second counter.
