摘要： Provided is a technique for limiting the radial displacement between a metal shell and an insulator in a spark plug. At the time of manufacturing a spark plug with a metal shell and an insulator, the metal shell and the insulator are assembled together by, while allowing relative positional displacement between the metal shell and the insulator in an axial direction (O-O), limiting relative positional displacement between the metal shell and the insulator in a radial direction intersecting with the axial direction in such a manner that the amount of deviation between an axis of the metal shell and an axis of the insulator becomes less than or equal to a predetermined level.

摘要： A spark plug includes an electrode tip assembly located at an axially-facing free end surface of an electrode body. The electrode tip assembly includes an electrode tip body and a firing tip and has a longitudinal axis that is generally perpendicular to a longitudinal axis of the electrode body. The electrode tip body may be a Ni-alloy piece and is attached to the electrode body, and the firing tip may be an Ir-alloy piece with a sparking surface that faces a spark gap. The electrode body may include a groove formed in the axially-facing free end surface that is useful to help position the electrode tip assembly for attachment. The spark gap can be formed between opposing electrode tip assemblies, and the size of the spark gap can be adjusted during assembly without the need for bending the electrode body.

摘要： An object of the present invention is to efficiently adjust a positional difference (measured along the direction perpendicular to the center electrode axis) between the center electrode (CE) axis and the center of the earth electrode (EE). The CE tip and EE end tip surface are illuminated from the front of the EE tip tip surface, thereby picking up their images. The image processing unit calculates the positional difference between the CE axis and EE center. Here, the EE center is defined by an area centroid of the EE tip surface area, thereby improving a measurement accuracy. The adjustment unit connected with the image processing unit causes the actual positional difference to decrease by moving EE by the that calculated positional difference, taking a prescribed spring-back into consideration. EE is moved by a jig moved by a screw rotated by a motor.

摘要： A noble metal tip of a grounding electrode is inclinedly disposed with respect to a noble metal chip of a central electrode by an angle &agr; so that a discharging gap is narrow at a side closer to one end of the grounding electrode and wide at the opposite side closer to the other side of the grounding electrode. When the discharging gap has expanded to a certain extent due to exhaustion of the noble metal tips of the electrodes, the re-gapping adjustment is performed to decline or push the noble metal tip of the grounding electrode toward the noble metal tip of the central electrode so as to decrease the angle &agr;. Thus, the discharging gap can be adjusted to an adequate value.
摘要翻译：接地电极的贵金属端部相对于中心电极的贵金属芯片倾斜角度α，使得放电间隙在靠近接地电极的一端的一侧较窄，并且在相对侧宽更接近接地电极的另一侧。当放电间隙由于电极的贵金属端部的耗尽而扩大到一定程度时，进行再间隔调整以将接地电极的贵金属电极顶端朝向中心电极的贵金属端头以减小角度α。因此，可以将放电间隙调整到适当的值。

摘要： According to one example, a spark plug gapping tool includes a first side handle, a second side handle, a middle handle, and a pusher that are made of a non-metallic material. The middle handle is positioned in-between the first side handle and the second side handle, and has a stopper surface and an insert slot that can receive a feeler gauge insert. The pusher is rotatably positioned in-between the first side handle and the second side handle, and has a hollow housing that can receive a terminal end of a spark plug. In operation, a distal end of the middle handle and distal ends of the side handles can move closer together, when a proximal end of the middle handle and proximal ends of the side handles are moved closer together by a user's hand, so as to gap the spark plug.
