構造。 The lower surface of the cylinder head, which faces the top surface of the piston, has a chevron-shaped shape that is concave in the direction of the cylinder row, and the intake valve and exhaust valve are arranged on the cylinder head so as to diverge from each other at an angle. The surface is shaped like a mountain with its central part raised, and the bottom surface of the combustion chamber formed on the top surface of the piston and facing the fuel injection valve is also shaped like a mountain with its central part raised to match the mountain-shaped shape. The combustion chamber structure of a direct injection diesel engine is characterized by:
