摘要： [Objective] To provide a technique for easily judging whether or not an insulator is cracked, in the process of manufacture of a spark plug. [Means for Solution] A method for manufacturing a spark plug includes an assembling step of assembling an insulator into a metallic shell through insertion of the insulator into the metallic shell from an axially rear end opening portion of the metallic shell. The assembling step includes a displacement restricting step of restricting a relative positional displacement between the metallic shell and the insulator in a radial direction intersecting with the axial direction so as to reduce eccentricity between the axis of the metallic shell and the axis of the insulator to a predetermined value or less while allowing a relative positional displacement between the metallic shell and the insulator in the axial direction. In the assembling step, whether or not the insulator is cracked in the assembling step is judged by detecting acoustic emission from the insulator.

摘要： PROBLEM TO BE SOLVED: To provide an evaluation test method of a material for an internal combustion engine capable of evaluating, with a simple facility, whether or not particles are easily generated on the surface of a material for an internal combustion engine such as an electrode of an ignition plug and an electrode material provided for the engine of an automobile.SOLUTION: The sample constituted of a nickel base material is immersed in a corrosion liquid (aqueous solution containing acid and sodium chloride). The sample immersed in the corrosion liquid is exposed to flames of engine oil, and further heated. A Ni concentration phase increased in Ni concentration by lacking an additive element in a surface layer region of the sample is formed by immersing the sample in a specific corrosion liquid. The component in the engine oil is put into an active state so as to be made to contact the sample by exposing the sample having the Ni concentration phase to the flames of an engine oil, and a low melting point phase is formed in the surface layer region of the sample. The sample having the low melting point phase is heated so as to melt the low melting point phase, and the sample is solidified again. Thereby, the particles and the like can be formed according to the material quality of the sample. The occurring tendency of the particles can be evaluated by a simple facility even without using a testing engine.
摘要翻译：要解决的问题：提供一种用于内燃机材料的评价试验方法，其能够以简单的设备评价在诸如电极的内燃机材料的表面上是否容易产生颗粒的火花塞和为汽车的发动机提供的电极材料。解决方案：将由镍基材料构成的样品浸入腐蚀液（含有酸和氯化钠的水溶液）中。将浸在腐蚀液中的样品暴露于发动机油的火焰中，并进一步加热。通过将样品浸入特定的腐蚀液中而形成样品的表层区域中缺少添加元素的Ni浓度增加的Ni浓度相。发动机机油中的成分被置于活性状态，以使与Ni浓度相的样品相接触的发动机油的火焰接触样品，并且在表层中形成低熔点相样品区域。将具有低熔点相的样品加热以熔化低熔点相，并且样品再次固化。因此，可以根据样品的材料质量形成颗粒等。即使不使用测试引擎，也可以通过简单的设备来评估颗粒的发生趋势。
