  • Control Of The Air-Fuel Ratio Of Carburetors (AREA)

Abstract

PURPOSE: To dilute air-to-fuel ratio and increase restartability in such a way that a secondary side throttle valve controlling spring shoe of a twin carburetor is moved once backward at the time of restarting in more than the determined temperature, and the secondary side throttle valve is released.
CONSTITUTION: A secondary side throttle valve 5' is opened and closed by means of an actuator 7 to actuate by Venturi combined negative pressrure. A solenoid valve 19 is arranged on the negative pressure path 18 to communicate the negative pressure chamber 10 of the acturator 7 to a Venturi 17. A spring shoe 13 which can be moved backward by means of electric conduction to a coil 14 is arranged in the negative pressure chamber 10 of the actuator 7. In addition, an intake air temperature sensor 27 and a starter switch 29 are connected to the coil 22 of the valve 19 and the coil 14 of the actuator 7, at the restarting time in more than the determined temperature, negative pressure in the negative pressure chamber 10 is decreased, and the throttle valve 5' is released by means of moving a diaphragm 9 backward.
