<p>PROBLEM TO BE SOLVED: To improve durability and reliability by constituting a collector and a manifold of an upper and lower resin molded body, and mounting a throttle device to the lower molded body. SOLUTION: A lower molded body 12 of an inlet system 11 is constituted of a collector bottom case 13 and a manifold lower divided body 14. An upper molded body 19 is constituted of a collector upper case 20 and a manifold upper divided body 21, and joined onto the lower molded body 12. A mounting pan 16 of the lower molded body 12 is mounted to an engine body 1 of a horizontal opposed type, while a manifold 24 which extends from a collector 23 to right and left is connected to each cylinder 2. One end side of a throttle device 25 is mounted to the collector bottom case 13 of the lower molded body 12, and connected to the collector 23. The other end side of the throttle device 25, in addition, is connected to an air cleaner 28 through a duct 27.</p> |
