Abstract
PURPOSE: To blast fuel smoothly in the range from low speed operation to middle and high speed operation and to atomize fuel properly in low speed operation range by injecting fuel to the upstream side of a throttle valve through a cut-off made when it inclines at the lowest point.
CONSTITUTION: An air measuring member 5 and throttle valves 9, 10 are provided in a suction pipe. With a difference of pressures in front of and in rear of said member 5 kept at a specified value, an air measuring mechanism C measures air suctioned from the opening of the member 5. A fuel measuring mechanism B keeps a pressure at a specified value associated with an opening area of the member 5. The fuel feed system includes the air measuring mechanism C and the fuel measuring mechanism B and injects fuel measured by the mechanism B into the up-stream of throttle valves 9, 10. A cut-off 14 is made in the primary throttle valve 9 which inclines to the lowest. Fuel from an injector 8, running through the cut-off 14 at high speed, flows to a suction manifold 18 through it, that is blasted to be stomized
