    摘要: In a spark plug (100), the resistor composition constituting a resistor (15) contains semiconductive ceramic particles, offering a superior load life characteristic. Also, the value of (&agr;2−&agr;1)/&agr;1>=−0.30, where a value of electric resistance between a terminal (13) and a center electrode (3) is &agr;1 at 20° C. and &agr;2 at 150° C., so that deterioration of the radio frequency noise prevention performance at high temperatures can be effectively suppressed. The resistor composition contains semiconductive ceramic particles whose temperature coefficient of electric resistance shows a positive value, or a negative value of relatively small absolute value, (e.g., TiO2 particles having a rutile type crystalline structure, titanate or zirconate of alkali earth metal elements, titanium suboxide, etc.), or titanium metal. Thus, the invention provides a resistor-incorporated spark plug which is enabled to offer a stable load life characteristic even when a high load acts thereon, and which is unlikely to deteriorate in the radio frequency noise prevention performance even under high temperatures.

    摘要: In a spark plug, a resistor is placed between a terminal and a center electrode within a through hole of an insulator. The through hole of the insulator has a first portion which allows the center electrode to be inserted therethrough, and a second portion which is formed on a rear side of the first portion so as to be larger in diameter than the first portion and which accommodates the resistor therein, where the second portion is connected to the first portion via a connecting portion including a two- or more-stepped reduced-diameter portion. Then, an electrically conductive glass seal layer is placed at a position corresponding to the connecting portion between the resistor and the center electrode. When the glass seal layer is formed by filling electrically conductive glass powder and its heating and compression, the pressurizing cross-sectional area in the axial direction is reduced to an extent of diameter reduction by the reduced-diameter portion of the connecting portion, so that a sufficient compressing force can be ensured in the event that the pressurizing force is lost, for example, due to friction between the upper filler material (e.g., resistor material powder) and the wall surface of the through hole. By virtue of this arrangement, the sintering of the glass seal layer progresses sufficiently so that the burns of carbon in the glass seal portion and the oxidization of metal components become unlikely to occur. Thus, such trouble as increase in conduction resistance can be avoided over a long term.

    摘要: Resistor compositions for producing a resistor for use in resistor-incorporated spark plugs and comprising a glass, an inorganic aggregate, and carbon black and/or a carbonaceous substance as a regulating agent for resistance value, with or without a stabilizing agent for resistance under load of the resistor, are now modified by addition of a reducing metallic powder such as powder of Al, Mg, Zn, Sn, Ti, Zr, Fe, Ga and Ag or alloys thereof, to improve the service life characteristics under load of the resistor. Such compositions are further modified by additional presence of a ceramic aggregate of a particle size of 100 to 800 .mu.m, to improve the electric wave noise-preventing property.
