Abstract

PURPOSE: To improve operational performance, to purify exhaust and to economize fuel, by arranging this system so that low-speed fuel uniformly atomized can stably be fed to an engine.
CONSTITUTION: In a device that sucks air from a slow air bleed 32 by the negative pressure of an intake passage 1 of a downstream of a throttle valve 3 generated in relation to the opening of the throttle valve 3, sucks liquid fuel from a slow fuel jet 37 and mixes the air and the fuel and supplies the mixture into the intake passage 1 from an idle hole 4, a first mixing passage 36 communicated with an air passage 33 from the slow air bleed 32, a second mixing passage 34, which is communicated with the passage 36, which upper end is provided with a mixing promoting air bleed 35 and which opens the idle hole 4 at the lower end, and a by- path passage 31, which one end is communicated with a rear stream of the slow air bleed 32 and which other end with a by-path hole 5, are installed. An above- mentioned arrangement can stably feed low-speed fuel uniformly atomized, thus improving the performance of an engine.
