ABSTRACT:
Engine revolutions are divided into plurality of ranges and it is assumed that engine revolutions are proportional to the angle of lead of the ignition time in each range. Upon receipt of a signal representing engine revolutions, a range to which the signal belongs is determined and the data including a proportional coefficient of that range is read out of an address of a memory corresponding to the range, thus determining an angle of lead according to the data.
