PURPOSE:In an internal-combustion engine where suction path at the downstream of fuel injection valve is splitted into two through a partition, to achieve good acceleration by suppressing adhesion of fuel to the inner wall face of second suction path. CONSTITUTION:First and second suction paths 13, 14 are formed in suction manifold 10 while being separated with partition 12. A fuel injection valve 16 is arranged in first suction path 13 while said paths 13, 14 are communicated through a communication hole 15 and second suction control valve 18 is arranged in second suction path 14 at the downstream of said hole 15. The fuel injection valve 16 is arranged such that large amount of fuel is fed into first suction path 13 while small amount of fuel is fed into second suction path 14 to suppress adhesion of fuel to the inner wall face of second suction path and suction control valve upon closing of suction control valve. |
