摘要： In a multi-polarity type spark plug for an internal combustion engine, a tubular insulator is supported within a cylindrical metallic shell through which a spark plug is to be attached to an internal combustion engine. A center electrode is placed within the insulator, a front end of the center electrode being directed toward a combustion chamber of the internal combustion engine from a front end of the metallic shell so as to extend beyond a front end of the insulator. First and second ground electrodes are each connected to the front end of the metallic shell, the first ground electrode forming a first vertical spark gap with a front end surface of the center electrode which directly opposes an elevational side of the center electrode, and the second ground electrode forming a second horizontal spark gap with an elevational side of the center electrode. An angle .theta.a is limited as 60.degree..ltoreq..theta.a .ltoreq.150.degree. in which the angle .theta.a is taken when the first ground electrode forms against the second ground electrode with the center electrode as an axial center.

摘要： A spark plug having a center electrode 2 formed from an electrode base material 2n, which is made of an Ni alloy containing an alloy component (e.g., Cr) capable of forming an oxide semiconductor having a resistivity of negative temperature coefficient. Thus, a corrosion suppression layer originating from the components of the electrode base material is formed on the surface of a tip end portion of the insulator 3, so that corrosion (channeling) of the surface of the tip end portion of the insulator 3 due to creeping spark discharge can be effectively suppressed. In addition, when the constituent metal of the electrode base material 2n has a coefficient of thermal conductivity of 17 to 30 W/m·K, the heat transfer performance of the electrode is enhanced, so that durability against electrode consumption can be greatly improved.

摘要： In a snap-in type spark plug voltage probe device, the insulator base has an upper half and a lower half, both ends of which are integrally connected by means of a flexible portion. The upper half and the lower half have a plurality of grooves in which spark plug cables are placed. The upper half and the lower half are joined together by the flexible portion when in a closed position. The upper half has an opening to receive a protrusion provided on the lower half of the insulator base to maintain the upper half of the insulator base along the grooves, providing static capacity between the electrode layer and the spark plug cables when voltage is applied across the spark plugs. A lead wire electrically connects the electrode layer to a microcomputer so as to analyze the burning condition based on the static capacity between the electrode layer and the spark plug cables. An electrical shield layer is embedded in the insulator base in the proximity of the electrode layer and connected to the internal combustion engine by way of a ground wire located at a side of the electrode layer remote from the grooves so as to electrically shield the electrical layer. An insulator sheet is embedded in the insulator base and located between the electrode layer and the electrical shield layer.
