装置。 A swirl chamber peripheral wall 3 surrounding the swirl chamber 2 of the pre-chamber type swirl chamber type combustion chamber of the water-cooled diesel engine E is formed inside the cylinder head 6 at a position eccentric from the main combustion chamber 1. A swirl chamber cap 11 is fitted and fixed into a cap fitting hole 10 formed in the lower half, and a nozzle 9 is opened diagonally downward toward the axis of the main combustion chamber 1 in the bottom wall of the swirl chamber cap 11. In a swirl chamber cap mounting device for a pre-chamber swirl chamber type combustion chamber of a water-cooled diesel engine, a portion outside the outer peripheral surface of the main combustion chamber 1 between the fitting surfaces of the swirl chamber cap 11 and the cap fitting hole 10. By drilling a positioning fitting hole 13 in the positioning portion and fitting the positioning cylindrical pin 14 into the positioning fitting hole 13, the vortex chamber cap 11 is positioned in the circumferential direction, and the cylinder of the cylindrical pin 14 is positioned. The lower end 15 of the hole is connected to the cylinder 4 of the cylinder block 5.
The upper end 16 of the cylindrical hole is connected to the cylinder head 6.
Head jacket portion 8 on the outer periphery of the swirl chamber peripheral wall 3
A swirl chamber mouthpiece mounting device for a subchamber type swirl chamber type combustion chamber of a water-cooled diesel engine, characterized in that the swirl chamber is connected to the combustion chamber of a water-cooled diesel engine.
