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 corona igniter (20) includes an electrode gap (28) between the central electrode (22) and the insulator (32) and a shell gap (30) between the insulator (32) and the shell (36). An electrically conductive coating (40) is disposed on the insulator (32) along the gaps (28, 30) to prevent corona discharge (24) in the gaps (28, 30) and to concentrate the energy at a firing tip (58) of the central electrode (22). The electrically conductive coating (40) is disposed on an insulator inner (surface 64) and is spaced radially from the electrode (22). The electrically conductive coating (40) is also disposed on the insulator outer surface (72) and is spaced radially from the shell (36). During operation of the igniter (20), the electrically conductive coating (40) provides a reduced voltage drop across the gaps (28, 30) and a reduced electric field spike at the gaps (28, 30).

摘要： A spark plug (10) includes an intermediate connecting pin (54) disposed in the central passage (28) of an the insulator body (12). The connecting pin (54) seats in an intermediate taper section (72) within the central passage (28), which is generally frustoconical and establishes a transition between a first larger diameter of the central passage (28) and a second smaller diameter. The intermediate tapered section (72) is located longitudinally above a filleted transition (26) feature of the insulator body (12) exterior. A pin head (53) of the connecting pin (54) has a complementary tapered under-cut and seats against the intermediate tapered section (72) to provide self-centering of the connecting pin (54) without trapping gas during the assembly process. The intermediate taper section (72) also provides an increase in insulator wall thickness which improves dielectric capacity and structural integrity of the insulator (12).

摘要： A monolithic, multilayer heating element (26, 126, 226) forms the high temperature tip (22, 122, 222) of a glow plug assembly (20). The heating element (26, 126, 226) includes a conductive core (48, 148, 248) which is surrounded by an insulator layer (50, 150, 250), which in turn supports a resistive layer (52, 152, 252). An optional conductive jacket (172) can surround the resistive layer (152). These layered components are pre-formed in prior operations and then assembled one into the other to form a precursor structure. The precursor structure is transferred to a die (54, 64, 164), where it is compressed to fom a so-called green part having dimensional attributes proportional to the finished heating element (26, 126, 256). The individual layers remain substantially intact, with some boundary layer mixing possible to enhance material-to-material bonding. The green part is sintered to bond to various materials into an essentially solid mass.

摘要： A multilayer ceramic structure is formed by building up a plurality of layers by sequentially coating a substrate with a series of suspensions comprising particles in a fluid medium. A composition of the sequential layers are varied to produce a structure with the desired properties. The thickness of the layers can be controlled by rheological properties of the suspension and/or by the utilization of a gelling or coagulating agent. An advantage of this method is that complete drying between the subsequent coatings is not required.
