Abstract

PURPOSE:To obtain the ignition timing characteristic with the advanced angle having a prescribed inclination by advancing the position where the first output of an integrator reaches the second standard value, namely the position where trigger signal is generated, to the prescribed cank position side, as the number of revolution of an engine increases. CONSTITUTION:The crank angle alpha from the prescribed crank position T1 where angular signal is generated to the position where the discharge voltage of the output voltage reaches the standard voltage V2 is shown in alpha=beta-6N (V2.Capacity of condenser 13/I2), with the number N of revolution of an engine, angle beta in discharge range, standard voltage V2, and discharge current I2. As beta is constant independently of the number of revolution, if the standard voltage V2 and the capacity of the condenser 13 are constant, the crank angle alpha is determined as the funtion of only the number N of revolution and reduces proportionally with the rise of the number of revolution. Therefore, the starting-up timing of the output voltage E of a comparator 16 advances, and the trigger voltage F generating timing advances with the rise of the number of revolution, and thus the ignition timing characteristic with advanced angle having a prescribed inclination can be obtained.
