摘要： A spark plug for an internal combustion engine has a center electrode, a ground electrode or both that includes an electrode material that is a Pt-based alloy. The electrode material may include platinum (Pt), at least one active element like aluminum (Al) or silicon (Si), and at least one high-melting point element such as ruthenium (Ru), iridium (Ir), tungsten (W), molybdenum (Mo), rhenium (Re), tantalum (Ta), niobium (Nb), chromium (Cr), or a combination thereof. In at least some of the disclosed alloys, the aluminum (Al) and/or silicon (Si) contributes to the formation of a thin protective oxide layer on a surface of the electrode material.

摘要： A glow plug (10) which includes an annular metal shell (12), thermally conductive tubular sheath (20), electrode (22), resistance heating element (24), and electrically insulating, thermally conductive powder (26). A metallic seal (28) is disposed in an open end of the sheath (20) in sealing engagement with the electrode (22). An insulating layer (54) is formed on the outer surface of the electrode (22) so as to prevent electrical conductivity between the metal seal (28) and the electrode (22). An optional secondary metal layer (56) may be disposed between the insulating layer (54) and the metal seal (28).

摘要： A spark plug and a method of manufacturing the same, where the spark plug has a metal shell, an insulator, a center electrode, a ground electrode, and a gasket located over a threaded portion of the shell and used to seal the spark plug against a cylinder head. Once the gasket is attached on the spark plug, it is shrunk to become a post-formed gasket with an inner diameter that prevents the post-formed gasket from slipping over a threaded portion of the metallic shell. This process may be carried out with a collet type machine that produces a post-formed gasket that is flat and has a substantially uniform thickness, which can improve the sealability of the gasket. This may be important when the spark plug is installed in a cylinder head made from a lost foam casting process or other process that creates a somewhat porous sealing surface.

摘要： An electrically conductive glass seal for providing a hermetic bond between an electrically conductive component and an insulator of a corona igniter is provided. The glass seal is formed by mixing glass frits, binder, expansion agent, and electrically conductive metal particles. The glass frits can include silica (SiO2), boron oxide (B2O3), aluminum oxide (Al2O3), bismuth oxide (Bi2O3), and zinc oxide (ZnO); the binder can include sodium bentonite or magnesium aluminum silicate, polyethylene glycol (PEG), and dextrin; the expansion agent can include lithium carbonate; and the electrically conductive particles can include copper. The finished glass seal includes the glass in a total amount of 50.0 to 85.0 weight (wt. %), and electrically conductive metal particles in an amount of 15.0 to 50.0 wt. %, based on the total weight of the glass seal.

摘要： A welding system for welding small precious metal firing tips to spark plug electrodes, such as ground and/or center electrodes. According to one embodiment, the welding system includes a firing tip storage assembly and a firing tip welding assembly, where the firing tip storage assembly uses pressurized gas introduced at the bottom of a part container to float or lift the firing tips so that the firing tip welding assembly can more easily acquire them with a vacuum-driven nozzle that also doubles as a welding electrode. The firing tip welding assembly is mounted to a robotic apparatus that can index or move the firing tip welding assembly between the firing tip storage assembly, a welding station and/or any other suitable positions.
