PURPOSE:To obtain uniform mixed gas by providing a guide to change the flow direction of mixed gas on the downflow side of fuel injection valve of the primary side air supply cylinder. CONSTITUTION:The lower end of the primary side air supply cylinder 6 is provided with the cylindrical piep 15 through which a mixed gas of the gas passing through aperture around the primary side throttle valve 12 and fuel injected is directed to the bottom of the mixing chamber 2 because the pipe 15 has an opening at the central part of the mixing chamber 2. The fine particles of fuel injected in a slant direction in the pipe 15 are vaporized during transportation by the inlet air current but comparatively coarser particles of the fuel wet the wall surface of the pipe 15 and then vaporized by the inlet air current. The fuel vaporized in this way and inlet air are uniformly mixed, flowed out of the pipe 15, and then dispersed when colliding with the bottom of the mixing chamber 2. |
