Abstract
PURPOSE: To permit the exact compensating control of idle revolution number to a target value by altering the waveform of pulse according to the turning direction (normal or reverse turning) of DC motor of an actuator for controlling throttle.
CONSTITUTION: A pulse signal sent from the ignition coil 600 is shaped its wave form at an engine revolution number detection circuit, put through the F/V converter 405 into the positive terminal of the comparator 406, and then compared with a voltage corresponding to a target revolution number put in a negative terminal. In this case, when the touch switch 301 of the throttle valve actuator is ON and an idle condition is detected, the idle detection circuit 420 outputs H level, and when the output of said comparator 406 is at H or L level, the transistors Tr3 and Tr6 or Tr4 and Tr5 turn ON through a logic circuit, the DC motor of the actuator is normally or reversely turned on the basis of the pulse width of the oscillator 401 or 402, and the opening degree of the throttle valve is altered.
