An apparatus for atomizing liquid fuel while mixing it with air, and varying the amount of each while maintaining a substantially constant fuel/air ratio for the intake manifold of an engine. The apparatus includes a frame (16) forming a passage (14) with a throat (44), with a second wall (56) of the passage being moveable toward and away from a stationary first wall (54) of the passage to vary the cross-section of the passage and thereby vary airflow. A fuel-carrying tube (24) has a proximal end (60) fixed to the first stationary wall and has a distal portion (62) that extends through a bore (64) in the moveable wall and with the moveable wall being slideable around the tube. The tube has at least one aperture (70) for flowing fuel into the passage, with the exposed aperture area being progressively increased as the moveable wall moves away from the stationary wall to flow a progressively increasing amount of fuel into the passage. The moveable wall is moved by a lever (134) that can be moved by the throttle of the engine.
Apparatus for producing a combustible air-fuel mixture for an engine, which includes a frame forming a passage through which air can flow in a downstream direction, said passage having opposite passage side walls and opposite passage end walls wherein one end wall is stationary and the other is moveable, said movable end wall being moveable closer and further from said stationary end wall to vary the cross-sectional area of the passage, said moveable end wall having a bore extending substantially parallel to movement of said moveable end wall, and including a fuel-carrying fuel tube slideably projecting into said bore but fixed with respect to said frame, so as said moveable end wall moves progressively away from said first end wall, a progressively increasing length of said fuel-carrying tube is progressively exposed to said passage, with said progressively increasing length of fuel tube having at least one perforation with perforation areas exposed to said passage that progressively increase in area as said moveable second end wall moves away from said first end wall, characterized by:
