Abstract

PURPOSE:To prevent a ceramic part from cracking by a method wherein a hard metal sprayed layer having a predetermined thickness is provided on the outside peripheral surface of a ceramic-made mouthpiece main body so that compressive stresses can be easily applied to the outside peripheral part of the ceramic body. CONSTITUTION:The mouthpiece A is provided at a predetermined position in a cylinder head 3 of the diesel engine so that a space inside the cylinder head 3 and the mouthpiece A constitutes the swirl chamber 4, which mouthpiece A is produced by forming the hard metal sprayed layer 2 of steel or the like having a thickness of about 1-3mm. on the outside periphery of the cylindrical mouthpiece main body 1 made of silicon nitride ceramic material, for example, and has a hollow part for constituting the swirl chamber. The mouthpiece A is designed to inject combustion gases into a combustion chamber 5 through an injection port 6 at the time of a combustion stroke. With the mouthpiece A constructed as described above, resistance to heat and impact can be obtained. In addition, since the compressive stresses are provided preliminarily at the outside peripheral part of the mouthpiece main body 1, the mouthpiece A can be fitted in the cylinder head 3 without bringing about such troubles as slipping-off.
