摘要
PROBLEM TO BE SOLVED: To solve a knocking problem by forming a fuel-mixed air group in a cylinder central axial region by improving a matching condition of in-cylinder air and an injection fuel group by using a new fuel direct injection combustion method, and to achieve the improvement of machine heat efficiency and low environmental pollution by reducing a loss of an air supply pump by using a constitution of a layered air-supply combustion method.SOLUTION: A fuel injection valve 7 is arranged at an upper part in a conical cylindrical combustion part 6 which is arranged substantially in the center of a cylinder head, and a fuel spray group 13 which injects fuel toward the center of a lower piston face 12 is dividedly injected as a narrow-angled annular spray group via the conical cylindrical combustion part. The mixture, the evaporation and activation of the fuel caused by the contact of the fuel group and air resulting from the flying-time elongation of the injection fuel group and the utilization of air in the cylinder center are progressed, and the arrival of the fuel to a cylinder wall is prevented.
