PURPOSE:To provide a suction system for an autobicycle wherein a piping of its suction system can be reduced in length without reduction of the capacity of a fuel tank, seuving to reduction of resistance to suction air passing therethrough and to simplification of the piping. CONSTITUTION:Suction pipes 12 of an engine 9 extend vertically upwardly from inside of banks 10, 11 into inside of a fuel tank 19 placed fixedly on a pair of tank rails 3. An upper opening 12a of each suction pipe 12 is opened within a connecting box 20 which is disposed between the tank rails 3 in the fuel tank 19. A connecting pipe 21 is disposed between the suction pipes 12 and extends substantially in parallel with the suction pipes 12 from downwardly from the connecting box 20. An air cleaner 22 is provided at the lower end of the connecting pipe 21. The suction system thus constructed eliminates the necessity of disposing the air cleaner 22 within the fuel tank 19 and enables a piping of the suction system to be reduced in length. |
