Abstract
PURPOSE: To prevent excessive condensation of air-to-fuel ratio in high load in such a way that when a secondary throttle valve of a twin carburetor is at its opening operation, are of a controlling air bleed path is augmented.
CONSTITUTION: Air-to-fuel ratio is controlled in such a way that a main supplementary air bleed 22 equipped with closing valve 25 and a slow supplementary air bleed 23 equipped with closing valve 25 are installed in a primary fuel system 1, and the closing valves 24, 25 are feedback-controlled. The main supplementary air bleed 22 provides a variable throttle 26 in which Venturi negative pressure communicates through a path 27, and air bleed rate in high load is decreased. Bisides, at the same time as a bypass path 31 equipped with electromagnetic valve 32 is installed on the bleed 22 making a detour around the throttle 26, the electromagnetic valve 32 is interlocked with a secondary throttle switch 33, and it is released at the time of releasing a throttle valve 13 to augment the bleed rate.
