PURPOSE: To burn even a little fuel by ignition by introducing a fuel spray injected from a fuel injection valve into a cylinder along a jet by a air curtain effect, and preventing the fuel spray from diffusing since a vertical swirl remains even if it is compressed. CONSTITUTION: The perpendicular is drawn in the center of a line connecting two intake valves 4, and a pipe is arranged in parallel to this center line 8 so as to coincide with a center line 9 to divide the area of a half of a cylinder into 1:1, and a jet from the pipe is equally introduced left and right into the cylinder. |
