ことを特徴とする、ディーゼルエンジンの燃焼室構造。In a diesel engine, a fuel injection nozzle is provided with a recess as a combustion chamber formed in the upper end surface of a piston that reciprocates within the cylinder, and injects fuel into the recess from a position offset from the center of the recess. The fuel injection nozzle injects fuel into the recess in a deep and large-capacity local part, and in a part other than the local part in the recess, the recess is shallower than the local part. A combustion chamber structure for a diesel engine, characterized in that a recessed portion with a small capacity is formed.
