燃焼室構造。 A squish generation system in which a columnar projection having approximately the same height as the top surface of the piston is erected approximately at the center of a combustion chamber provided at the top of the piston, and a squishing flow is generated radially outward on the upper surface of the head of the columnar projection. In addition to forming a surface, a plurality of spray guide notch grooves extending in a radial direction from the center are formed in the head of the columnar projection in response to the spray injected from a fuel injection nozzle provided above the head. and a combustion chamber structure for a direct injection diesel engine, characterized in that squish generation surfaces for generating squish flow radially inward are formed on the outer periphery of the top surface of the piston on the extension line of each notch groove. .
