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

Abstract

PURPOSE: To improve an accelerating property and to enable the treatment against an exhaust gas, by altering the quantity of fuel discharged from an accelerating pump depending on various conditions such as the warmed-up state of an engine, the degree of opening of a throttle valve, a quick or slow acceleration state, etc.
CONSTITUTION: An acceleration device is provided with an accelerating pump 3 having a fuel return passage 8 which communicates with a float chamber F. Detectors, 13, 14, 15 or the like, which detect at least one of various conditions such as the warmed-up state of an engine, the ratio of recycle of exhaust gas, the starting time of the secondary side action of a two-stage carburetor, etc., are used to quickly actuate a valve 9' provided in the fuel return passage 8 to increase or decrease the quantity of fuel which is discharged from the accelerating pump 3 to the carburetor. According to this constitution, the fuel discharge quantity of the accelerating pump 3 is controlled into an ideal state depending on the various conditions. This control is very effective to improve a running property and to purify the exhaust gas.
