Abstract: An electrode for an ignition device is made from a dilute nickel alloy which has improved resistance to high temperature oxidation, sulfidation, corrosive wear, deformation and fracture and includes at least 90% by weight of nickel; zirconium; boron and at least one element from the group consisting of aluminum, magnesium, silicon, chromium, titanium and manganese. The weight ratio of Zr/B may range from about 0.5 to 150, and may include amounts of, by weight of the alloy, 0.05-0.5% zirconium and 0.001-0.01% boron. The oxidation resistance of the alloy may also be improved by the addition of hafnium to the alloy in an amount that is comparable to the amount of zirconium, which may include an amount of, by weight of the alloy, 0.005-0.2% hafnium. Electrodes of dilute nickel alloys which include aluminum and silicon, as well as those which include chromium, silicon, manganese and titanium, are particularly useful as spark plug electrodes. These electrode alloys of the may also include at least one of cobalt, niobium, vanadium, molybdenum, tungsten, copper, iron, carbon, calcium, phosphorus or sulfur as trace elements, generally with specified maximum amounts. The ignition device may be a spark plug which includes a ceramic insulator, a conductive shell, center electrode and ground electrode. The center electrode, ground electrode, or both, may be made from the dilute nickel alloy of the invention. These electrodes may also include a core with thermal conductivity greater than that of the dilute nickel alloy, such as copper or silver or their alloys.

Abstract: A spark plug having a pair of independent spark gaps includes a shell, inner and outer insulators, a cylindrical electrode assembly, a center wire assembly, and a pair of ground electrodes. The cylindrical electrode assembly is generally located between the two insulators and delivers a first high voltage ignition pulse to a first spark gap. The center wire assembly is located in an axial bore of the inner insulator and delivers a second high voltage ignition pulse to a second spark gap. The two insulators and two electrode assemblies are all coaxially aligned within the shell so that both insulators can be rotationally symmetrical. The first spark gap is radially oriented while the second spark gap is axially oriented, and the first and second spark gaps are located at different axial positions and can fire independently of one another. A method of assembling the spark plug is also disclosed.

Abstract: An ignition and diagnostic system (10) for an internal combustion engine includes a sparking device (12) through which a low voltage diagnostic device (54) monitors a sensing feature, for example spark gap (30) conditions, during spark intervals and returns diagnostic feedback to an engine control module (56). A coil (44) is electrically operatively connected to the sparking device (12) through a lead wire (48). The lead wire (48) can be removed and reinstalled with respect to the sparking device (12) via a flexor joint (60) for installation and maintenance. The flexor joint (60) enables positive electrical contact during operation so that low voltage signals from the diagnostic device (54) are maintained even during severe vibration conditions. The flexor joint (60) includes in one embodiment a compression spring (62) which is fully compressed or over-compressed. In another embodiment, the flexor joint (60) comprises a tubular sleeve (64, 64′) having cantilevered upper tangs (70, 70′) which resiliently engage the lead wire (48), and lower tangs (76) which similarly engage the center wire (32) of the sparking device (12) in a resilient manner.
