ABSTRACT:
Herein disclosed is an ignition timing control system for an internal combustion engine, wherein an angular signal generated at a predetermined crank position is used so that the ratio of the angle, at which such a discharge output of the triangular wave of an integrator made operative to repeat its charging and discharging operations in a constant current as intervenes between each of the adjacent crank positions reaches a first predetermined value, is made constant relative to said angular signal thereby to preset a constant angle (.alpha.) and so that the time period, for which such a charge output of the triangular wave of said integrator as intervenes between each of the adjacent crank positions reaches a second predetermined value, is made constant relative to said angular signal thereby to preset a constant time period (t), whereby the timing, at which said charge output reaches the second predetermined value, is retarded because of said constant time period in accordance with the rise in the r.p.m. of said internal combustion engine so that the generation timing of a trigger output is retarded in accordance with the rise of the r.p.m. of said engine thereby to attain angle retardation characteristics having a constant gradient.
