燃焼室構造。 A cavity is recessed in the upper surface of the piston, and includes a sub-combustion chamber that communicates with the main combustion chamber through a communication hole, and that diffuses the flame from the communication hole to the main combustion chamber. A plurality of valve recesses are arranged in parallel in the cylinder head in a direction perpendicular to the opening direction of the communication hole, and a recess is formed in the cylinder head between the valve recesses so as to overlap the cavity when viewed from the top surface of the piston. The combustion chamber structure of a pre-chamber diesel engine.
