Abstract

PURPOSE:To eliminate an unstable combustion phenomenon at the time of starting by constituting the circuit so that it does not operate even when a light in pre- ignition is detected. CONSTITUTION:A photoelectric cell 6 is connected between the base of a transistor 7 and the anode of a thyristor 9. By this connection, the voltage supplied from a transistor 8 is impressed on a part shown by a signal S1 in the figure until the thyristor 9 is turned ON, even when the transistor 7 is turned ON to start the preignition, and it acts in the direction to turn the transistor 7 ON, but not to turn the same OFF even when the light of a plug in the preignition is detected and a resistance value lowers. Therefore, the transistor 7 continues to operate in a stable manner even if it receives noises, etc. and a certain time later the thyristor is turns ON, whereby an electromagnetic pump 2 is surely made to operate.
