PURPOSE:To simplify the construction by mutually connecting several carburetors having separate suction passages leading to each cylinder block, in such a way that the center lines of said suction passages almost agree with the bisector of the banking angle in a motor-cycle, etc. CONSTITUTION:On the body frame F of a motor-cycle, the first and the second cylinder blocks CB1, CB2 which are directed forward, and the third cylinder block CB3, positioned between said two cylinders and directed upward, are arranged in a V-form at a banking angle of 90 deg.. Carburetors C1 to C3, separately provided with suction passages which are connected to the suction port of each cylinder block, are mutually connected with their suction passages being nearly in agreement with the bisector of the banking angle, and are commonly connected to an air cleaner 6. Thereby the construction of connecting carburetors can be simplified, enabling connecting with the same part and reducing the number of parts, while eliminating the need for greatly curving the connecting pipe between the air cleaner and suction passages, reducing its length, and thus, improving the accelerating response. |
