Abstract

PURPOSE:To maintain high filling up efficiency at the time of a low load, over maintenance of the high filling up efficiency at the time of a high load, by connecting an inlet duct of a helical type suction port of a whirlpool part at a branch part with the edge of a whirlpool port and providing an opening and closing valve in the branch part. CONSTITUTION:A helical type suction port 6 is constituted with an inlet duct part A having a little bent axis a and a whirlpool part B, and a mixed gas outlet part 13 of the whirlpool part B is formed in a cylindrical form centering around a whirlpool axis b and opened into a combustion chamber. In this case, a branch duct 21 which is diverged from the inlet duct part A is formed on a cylinder head 3, an inlet opening part 22 of which is formed on a side wall 16 in the vicinity of the inlet opening of the inlet duct A, and an outlet opening 23 is formed on the tip of a side wall 15 at the edge E of a whirlpool. Then, a circular hole 24 which crosses a branch duct 21 is formed within the cylinderhead, and a bellows type opening and closing valve (flow control valve) 25 which is opened at the time of a high load is inserted into the circular hole 24.
