Abstract

PURPOSE:To improve the stability and the driving controllability of an engine by increasing the amount of lead angle by a certain degree in proportion to the number of revolution, in the controller which performs delayed angle by a certain degree when knock signal is generated and performs lead when the knock signal vanisheds. CONSTITUTION:When a knock pulse is entered into the 2d-terminal, a transistor 76 turns ON for the time to, and an electric current i1 flows in the parallel value C of condensers 71 and 72, and the voltage of an operation ampilifier 85 increases, the pulse DELTAV1 increases as shown by the equationIand delayed angle is generated. While, a transistor 77 is turned OFF for the time t1 with the pulse 2a of a every cycle monostable circuit, and an electric current i2 flows, and the voltage of the operation ampilifier 85 decreases, and the cycle DELTA2 is shown by the equation II. Thereof, as the electric current i3 flows in the condensers 71 and 72 with resitors 610-612, consequently the electric current i3+i2 flows, and the formulae DELTAVc=DELTAV2+DELTAV3; DELTAV3=1 deg./1sec. due to i3 will be applied in the operatuon amplifier 85. Therefore, as the characteristic of the retarding circuit of an ignition apparatus is the slant characteristic for the output of a knock controller, the lead angle becomes the sum of a constant lead per unit time and the lead in proportion to the revolution.
