Filed: 1987-03-11
Abstract: PURPOSE:To prevent the fluctuation of air-fuel ratio by selectively connecting an end part on the intake side of a variable length intake pipe to one of two air chambers different in intake resistance in adjusting the pipe length of the variable length intake pipe to increase the intake resistance as the pipe length becomes longer. CONSTITUTION:A slider 5 is positioned extremely left during low speed engine operation to come into contact with a fixed intake pipe 4, and a variable length intake pipe 3 therefore changes in its length into long size formed of the fixed intake pipe 4 and a flannel pipe 6. In this case, air is drawn in through the right end of the flannel pipe 6 from the secondary air chamber 26, and throttle twice by passing through the primary and secondary intake passages 21, 27. On the other hand, a servomotor 38 moves the slider 5 to the right through a drum 37 and an interlocking member 31 or the like during high speed engine operation to increase a gap between the slider 5 and the fixed intake pipe 4, and the variable length intake pipe 3 is therefore shortened in its length. Consequently, the air is drawn in through above-mentioned gap from the primary intake passage 21 and the primary air chamber 25.
