イーゼルエンジンの燃焼室。 In the combustion chamber of a diesel engine having a concave cavity at the top of the piston, a protrusion having an annular cross section is provided on the bottom surface of the cavity,
The shape of the protrusion is such that it is deepest at the center, gradually swells higher toward the outer periphery, and falls down from the swelled portion to the bottom surface of the cavity, thereby forming a circumferential surface facing the side wall surface of the cavity. The combustion chamber of a diesel engine is characterized by being formed in the shape of a crater.
