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

Abstract

PURPOSE: To simplify the construction of a carburetor with a secondary mixture tube penetrating into an intake pipe at the downstream of a throttle valve by making the secondary mixture tube as a mere secondary air tube so that the amount of bleed air influx into low speed fuel can be regulated.
CONSTITUTION: Under the operational condition other than decompression, a negative pressure reaction valve 23 is closed and a first and a second control valves 34 and 14 are closed and opened respectively. Therefore, while the engine is running at low or medium speed, both a first and a second tubes 11a and 11b are in a continuity status. The air flux in an air bleed tube 11 is regulated in rather excessive quantity with air jets 12a and 12b, and the mixture is rarefield comparatively. Besides, when the engine is turned down abruptly closing down all the throttle valves 4, the negative pressure reaction valve 23 is opened leading the negative pressure to negative pressure reactors 15 and 35, and the control valves 34 and 14 are losed and opened respectively. This allows the secondary air to be supplied to an intake pipe 1 located at the downstream of the throttle valves 4 through an air tube 31 and augmented fuel is ejected from low speed nozzles 5 and 6.
