Abstract
An air cleaner intake tube 6 which diverges in the direction from its open end is provided with radial holes 9 and 10 and a resonance chamber 11. The radial holes 9 and 10 are arranged in two rows 7 and 8 one of which is spaced a distance (0.1-0.2)L from the open end of the air intake tube 6, the other being disposed at a distance of (0.4-0.6)L from the open end thereof. The flow area of the holes 9 and 10 of each of the rows 7 and 8 amounts to (0.02-0.1)S, while the volume of the resonance chamber 11 is (O.25-0.7)V, where L is the length of the air intake tube 6; S is the cross-sectional area of the air intake tube 6 at locations of the radial holes 9 and 10; and V is the volume of the air intake tube 6. <IMAGE>
