ミックチャンバの組付は構造。The lower part of the auxiliary chamber is formed by a ceramic chamber fitted into the cylinder head, and the lower surface of the ceramic chamber on the main combustion chamber side is exposed to the main combustion chamber of the diesel engine, and the lower surface of the ceramic chamber on the side opposite to the main combustion chamber is exposed to the main combustion chamber of the diesel engine. Assembling the ceramic chamber by compressing the upper surface of the cylinder block through a gasket is structured such that the thickness of the side wall of the ceramic chamber on the side of the main combustion chamber is smaller than the thickness of the side wall on the side opposite to the main combustion chamber, The assembly structure of the ceramic chamber is characterized in that the thickness of the cylinder head wall surrounding the auxiliary chamber on the side of the main combustion chamber is larger than the thickness of the wall opposite to the main combustion chamber.
