Abstract
PURPOSE: To stably run an engine both at the starting and under a high load, by specifying the constitution of a modulator circuit.
CONSTITUTION: An OR unit 24, which operates a timer 26 through comparators 22, 23 connected to a reference voltage generator 21, is connected to a comparator 11. A switch 25 is connected to a reference wave generator circuit 30 and an output control circuit 10 for a power transistor 17 through an OR unit 27 and a switch 29. Thereby, the modulator circuit is formed. When the output signal 15 from an O2 sensor 15 has remained higher or lower than a slice level signal 16 over a predetermined time, the switch 29 is turned on and the output control circuit 10 is operated by the output of the reference wave generator circuit 30. Thereby, a solenoid 14 is energized to maintain a slow and a main actuators in central position. Thus, the purpose is attained.
