Claims

[Scope of utility model registration request]

The opening of the auxiliary combustion chamber leading to the main combustion chamber of the diesel engine is provided with a ceramic mouthpiece member in which a nozzle hole is formed to communicate the main combustion chamber and the auxiliary combustion chamber, and the opening and the ceramic mouthpiece are connected to each other. A metal ring is interposed between both ends of the outer circumference of the ceramic cap member and both ends of the inner circumference of the metal ring in order to concentrate compressive force on both ends of the outer circumference of the ceramic cap member. are in substantially linear contact along the circumference, or both ends of the outer periphery of the metal ring and both ends of the inner periphery of the opening are in substantially linear contact along the circumference. A pre-chamber diesel engine.
