7 and into the air cleaner communicating with this, but when it flows into the guide pipe 19, the opening 19 of this
d is frame trap 16, element 1 upstream of this
Since it is substantially perpendicular to the purification surface of frame trap 16 and element 15, it does not directly contact the purification surface of frame trap 16 and element 15, so that the frame trap 16 and element 15 are prevented from being contaminated by carbon, etc., as much as possible. The lifespan and durability of frame traps and elements will be improved.
尚以上の他、ガイド管１９を設けることにより吸気騒音
の低減効果もある。In addition to the above, the provision of the guide pipe 19 also has the effect of reducing intake noise.
