Abstract
PURPOSE: To control an idling rpm under such a low rpm as not to be unstable by controlling the fuel-air mixture control means of internal combustion engine by detecting vibration of engine.
CONSTITUTION: An intake system of internal combustion engine consists of a carburetor 6, throttle valve 5 and a manifold 4. The valve 5 anchors on a throttle positioners, which is a means of controlling the fuel-air mixture quantity through a lever 12. In a negative pressure chamber 13 of the positioner 8 the changing-over of the manifold is performed through a cross electromagnetic valve 19 as well as the negative pressure and air are changed over through an air filter 17. The signals of a vibration sensor 20, with which the engine is provided, are put in a vibration level detector circuit 21 to be operated in the comparing circut 22 together with the reference signals generating circut 23. And basing on the results therefrom the electromagnetic valve 19 is changed over to maintain the idling revolution to the extent of low revolution not generating vibration.
