摘要： A spark plug (10) for a spark ignited internal combustion engine includes a suppressor seal pack (54) interposed between an upper terminal stud (46) and a lower center electrode (60). The suppressor seal pack (54) includes a top layer of conductive glass (52) surrounding the bottom end (50) of the terminal stud (46) and a lower glass seal layer (58) surrounding a head (62) of the center electrode (60). A resistor layer (56) fills the space between the conductive glass layers (52, 58). The resistor layer (56) has a larger first cross-sectional area (76) at its upper end and a smaller second crosssectional area (78) at its lower end. A reducing taper (80) establishes a progressive transition between the greater and lesser cross-sectional areas (76, 78). The reducing taper (80) is located in a large shoulder region (LS) which is defined as the longitudinal dimension between the theoretical reference point (70) at the filleted transition (26) and the theoretical reference point (68) at the upper seat (17). The suppressor seal pack (54) is of the fired-in variety in which each layer (54, 56, 58) is separately filled as a granular material, tamped and then cold pressed using the terminal stud (46). The assembly is then heated in a furnace, then removed so that the terminal stud (46) can be used to hot press the suppressor seal pack (54) into a final, operative condition. The suppressor seal pack (54) has a length (SL) which is maximized by use of a positive "A" dimension (+A) defined as the longitudinal distance between the center electrode head (62) seat and the theoretical location (72) of the lower seat (19).

摘要： A spark plug (10) having an elongated ceramic insulator (12) includes numerous design features in various strategic locations. At least the ground electrode (26) is fitted with a rimmed, hemispherical metallic sparking tip (56) which controls rogue electrical arcing (62) and facilitates attachment techniques due to increased surface contact with the ground electrode (26). The various features of the spark plug (10) cooperate with one another so that the physical dimensions of the spark plug (10) can be reduced to meet current demands of newer engines without sacrificing mechanical strength or performance.

摘要： A spark plug (24) is used in an ignition system (10) of the type for creating a precisely timed spark to ignite an air/fuel mixture in an internal combustion engine. The spark plug (24) is provided with an integrated capacitor feature to increase the intensity of its spark. The capacitor feature is formed by applying metallic film (62, 64) to the inner (30) and outer surfaces of a tubular insulator (26). The insulator (26), made from an alumina ceramic material, forms a dielectric and sustains an electrical charge when an electrical differential is established between the inner (64) and outer (62) metallic films. The stored electrical charge is discharged with the firing of a spark in the spark gap (54). The inner (64) and outer (62) metallic films can be applied as a paint or ink directly to the surfaces of the insulator (26), or can be mixed with a glazing compound to form conductive coatings simultaneous with the glazing operation. Ganged (62') or serpentine (62") micro-plates can be formed within either or both of the inner and outer metallic films to increase the charge-carrying surface area. The metallic film (62, 64) is specially selected from materials that will not migrate into the porous matrix of the ceramic insulator (26). The metallic film (62, 64) is preferably gold, platinum, copper, or a platinum group metal.

摘要： A spark plug having a multilayer firing tip that minimizes the amount of precious metal used and a method of assembling a spark plug with a multilayer firing tip. The firing tip includes a discharge end and a weld end, with the weld end being connected to a center electrode, and more specifically to a base electrode on the center electrode. The weld end has a coefficient of thermal expansion, which is not between the values for the coefficients of thermal expansion for the discharge end and the base electrode. More specifically, the weld end has a coefficient of thermal expansion which is greater than the coefficients of thermal expansion for the discharge end and base electrode. The weld end is formed from Nickel and Chromium with a limited amount of additional elements. The spark plug is assembled by providing a first elongated material formed from the material used for the discharge end and a second elongated material formed from a material used for the weld end. The two materials are then joined to form a single joined material and are severed to create a firing tip. The firing tip is welded to the center electrode of the spark plug and more specifically, the base electrode.

摘要： A spark plug having a center electrode assembly that includes a center electrode and precious metal insert that is both mechanically interlocked and welded to the center electrode in a manner that permits trapped gases to escape from between the two components. Also disclosed is a method for manufacturing the same. During assembly, the precious metal insert is placed into a blind hole that extends axially into a lower end of the center electrode. Once in place, the center electrode is deformed around an enlarged head section of the insert to mechanically interlock the two components together. To further strengthen this attachment, the two components are welded together about their circumference. In one embodiment, the weld includes several interruptions that function as vapor vents for any gases that may be trapped. In other embodiments, a radially or an axially-extending vent hole is used in lieu of the weld interruptions.
