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

Abstract

PURPOSE: To economize fuel cost by making ineffective a temporary variation of the negative pressure in an intake path due to the rapid opening and closing operation of a throttle valve, for the negative-pressure corresponding valve.
CONSTITUTION: A negative-pressure transmission delaying apparatus 26 is arranged in a negative-pressure path which communicates between the negative pressure chamber 22 of an ordinary closed type negative-pressure coresponding valve 15 arranged in an auxiliary air bleed path 12 and a negative-pressure detecting hole 24 which detects the intake negative pressure of an engine, and a temporary variation of the intake negative pressure due to rapid opening and closing movement of a throttle valve 5 is made ineffective, for the negative-pressure corresponding valve 15. The constitution described above allows the fuel ratio to be improved in traveling in a street where the opening and closing operation of a throttle valve is repeated violently
