METAL SHELL OF GLOW PLUG FOR DIESEL ENGINES AND METHOD OF MANUFACTURING THE SAME |
摘要 |
A metal shell of a glow plug mounted on an engine head of a diesel engine and a method of manufacturing the same are disclosed. The metal shell has an improved multi-stage structure, which allows the metal shell to be easily manufactured regardless of overall length of the metal shell and allows a metal shell section fastened to the engine head and at least one of the other metal shell sections to have different material strengths, thereby increasing fastening strength of the metal shell to the engine head and preventing warpage of the metal shell while improving productivity while reducing manufacturing costs. The metal shell of a glow plug for diesel engines according to the invention includes a plurality of metal shell sections disposed in an axial direction of the glow plug and having different material strengths. |
