A cylindrical liquid cooling chamber 3 surrounding the auxiliary combustion chamber 2 of the diesel engine 1 is formed in the cylinder head 4, and the liquid cooling chamber 3 has an inlet 5 and an outlet for cooling liquid C. In a liquid cooling system for a diesel engine sub-combustion chamber, which has an opening in the liquid cooling chamber 3, the coolant C flows into one side A and the other B in the circumferential direction at the place where the coolant C flows from the inlet 5. A flow regulating body 7 for regulating the flow to one side A is provided on the side of one side A of the inlet 5, and an outlet 6 is provided on the side of the other side B when viewed from the flow regulating body 7. A sub-combustion chamber liquid cooling device for a diesel engine, characterized in that it is positioned and opened. 2 A diesel engine in which a cylindrical liquid cooling chamber 3 surrounding the auxiliary combustion chamber 2 of the diesel engine 1 is formed in the cylinder head 4, and an inlet 5 and an outlet 6 for the coolant C are opened in the liquid cooling chamber 3. In the sub-combustion chamber liquid cooling system of an engine, inside the liquid cooling chamber 3, at the place where the coolant C flows from the inlet 5, it separates into one side A and the other side B in the circumferential direction, and defines the split flow ratio. A sub-combustion chamber liquid cooling device for a diesel engine, characterized in that a diversion ratio regulating body 8 is provided opposite an inlet 5. 3 A diesel engine in which a cylindrical liquid cooling chamber 3 surrounding the auxiliary combustion chamber 2 of a diesel engine 1 is formed in a cylinder head 4, and an inlet 5 and an outlet 6 for a coolant C are opened in the liquid cooling chamber 3. In a sub-combustion chamber liquid cooling system for an engine, an inlet 5 is opened at a portion 10 near one end in the direction of the axis 9 of the liquid cooling chamber 3, and an outlet 6 is opened at a portion 11 near the other end. A spiral guide body 12 that spirally guides the cooling liquid C from the inlet 5 side to the outlet 6 side within the
A sub-combustion chamber liquid cooling device for a diesel engine, characterized in that it is provided in a liquid cooling chamber 3.
