Abstract

PURPOSE: To improve the formation of fuel minute particles and consumption ratio and to obtain the apparatus having a superior correspondence to the variation of intake amount and permitting precise measurement of intake amount by arranging a control apparatus for the output of electrical signals relating to the shift amount of a movable piston arranged in an intake passage.
CONSTITUTION: A movable piston 5 is inserted into an intake cylinder 3, and with said movable piston 5 and a fixed wall 19, a variable venturi part 6 is formed to vary the draft sectional area. The movable piston 5 slides in a suction chamber 7, and the negative pressure generated by the air flow in the variable venturi part 6 is introduced into the suction chamber 7 through a draft hole 9. A control apparatus 28 allows a fuel jet valve 20 to be operated with the output which permits the gushing of proper fuel amount by means of signals.
