ジンの燃焼室構造。A diesel engine includes a combustion chamber that opens at the top surface of a piston, and a protrusion that protrudes inward from a side wall of the combustion chamber, and the atomized fuel injected into the combustion chamber is transferred to the protrusion. The protrusion is formed so that the height in the combustion chamber changes along its circumferential direction so that the protrusion is distributed in multiple layers from the upper part to the lower part of the combustion chamber according to the displacement of the piston. , diesel engine combustion chamber structure.
