特徴とする、ディーゼルエンジンの燃焼室構造。In a diesel engine having a swirl chamber connected to the upper part of the main chamber of the cylinder via a nozzle hole, the nozzle hole is designed to generate a horizontal and directional swirl in the air flowing into the swirl chamber through the nozzle hole. The central axis of the opening on the swirl chamber side is formed to be offset laterally from the center of the swirl chamber, and the air flowing into the swirl chamber side opening of the nozzle hole through the nozzle hole is formed in a gently inclined state. A combustion chamber structure for a diesel engine, characterized by being provided with a gentle inclination mechanism for directing incoming air toward a side wall of a swirl chamber.
