Abstract

PURPOSE:To simplify a constitution by forming triangular waves with a signal of an advanced angle and making the same equal advanced angle with a voltage of the triangular waves, imposed with a constant bias voltage, and those of two triangular waves proportional to a revolution, in an electronic advanced angle control circuit for two cylinders. CONSTITUTION:In an electronic advanced angle device for a two cylinders type engine having an angle of 80 deg. between an L-cylinder and an R-cylinder and an ignition advanced angle range of 30 deg., when a rotor is rotated, a signal A from a pulser 2 for the L-side cylinder and a signal B from a pulser 3 for the R-side cylinder, lagging from a wave form of the signal A by 80 deg., are generated. The signals A, B are input into FF4, 6 and signals C, D, F, G are output from respective terminals. The signal C is converted into a signal E through an integrating circuit plus bias voltage V1 circuit 5 and the signals C, D, G are converted into a signal H through an integrating circuit 7, thereafter, both of them are output toward a comparator 8 respectively. The comparator 8 outputs predetermined signals I, J and the signals I, J are distributed to the L, R-cylinders by an L, R distributor 9.
