Abstract
PURPOSE: To improve fuel consumption, by such means that rotary speed of an engine at its idling operation is promptly focused to preset idling rotary speed by gradually lowering reference voltage used as the voltage corresponding to rotary speed of the engine.
CONSTITUTION: An idling speed controller comprises a rotary speed detecting circuit 2, consisting of a pulse generator 3 for generating a frequency pulse corresponding to engine rotary speed, waveform shaping circuit 4 and F-V converter circuit 5, and its output is compared in a comparator circuit 8 with reference voltage of a reference voltage generating circuit 7 for generating reference voltage corresponding to output voltage of a temperature sensor 6. In this case, to the reference voltage generating circuit 7 output of the rotary speed detecting circuit 2 is further input to generate the reference voltage. On the basis of deviation output of the comparator circuit 8 a control signal is fed to an idling supply air quantity controller 10 through a control signal generating circuit 9, then an engine 1 is controlled by output from the above and kept to its preset idling rotary speed.
