PURPOSE:To permit the uniform dispersion of fuel into each intake port by arranging a fuel injection valve in which the center axis line of an injection hole part is set so as to direct a specific direction, in the convergence part of three branched air feeding ports opened to a combustion chamber. CONSTITUTION:Three branched air feed ports 7-9 are connected to a combustion chamber formation part in which a cylinder head 4 is formed, and a pair of branched exhaust ports 11 and 12 are connected. The upstream parts of the three branched air feeding ports 7-9 are converged at a convergence part 10 connected to a suction passage 9, and a fuel injection valve 50 having a single injection hole part 50a is arranged in the convergence part 10. The fuel injection valve 50 is arranged so that the center axis line 51 of the injection hole part 50a is directed to the drection passing through the center position x of the triangular plane formed by the line connecting the centers Q, P, and R of the opened port parts 7A-9A for the combustion chamber 5 of the branched air feeding ports 7-9. |
