Abstract: An igniter (20) includes an outer insulator (24) formed of an outer ceramic material hermetically sealed to a conductive core (26). The conductive core (26) is formed of a core ceramic material and a conductive component, such as an electrically conductive coating applied to the core ceramic material or metal particles or wires embedded in the core ceramic material. The conductive core (26) is typically sintered and disposed in the green outer insulator (24). The components are then sintered together such that the outer insulator (24) shrinks onto the conductive core (26) and the hermetic seal forms therebetween. The conductive core (26) fills the outer insulator (24), so that the conductive core (26) is disposed at an insulator nose end (34) of the outer insulator (24) and the electrical discharge (22) can be emitted from the conductive core (26), eliminating the need for a separate firing tip.

Abstract: The invention provides a system and method for controlling corona discharge and arc formations during a single corona event, i.e. intra-event control. A driver circuit provides energy to the corona igniter and detects any arc formation. In response to each arc formation, the energy provided to the corona igniter is shut off for short time. The driver circuit also obtains information about the arc formations, such as timing of the first arc formation and number of occurrences. A control unit then adjusts the energy provided to the corona igniter after the shut off time and during the same corona event based on the information about the arc formations. For example, the voltage level could be reduced or the shut-off time could be increased to limit arc formations and increase the size of the corona discharge during the same corona event.

Abstract: A power amplifier circuit that has an inductor and capacitor connected to one end of the output winding of an RF transformer. The other end of the output winding is connected to a current sensor that in turn is connected to ground. The transformer has two primary windings. Both primary windings have one end connected to a voltage supply. The other end of each primary winding is attached to a switch. All three windings are wound around a core. Current flowing from the DC voltage supply to the switches causes a magnetic flux in the core. A voltage is generated on the secondary winding current sensor by the current that flows through the igniter. This voltage is fed back to the switches, controlling on and off timing. Voltage is provided to the igniter or pulled from the igniter when the current traveling into or from the igniter is at zero.

Abstract: Methods of making an insulator for a condition sensing spark plug and tooling that can be used to perform the various methods, the tooling and methods involving machining one or more channels in the insulator body. The machined channels can be used to accommodate one or more wires from a sensing, display, or processing device. In one particular example, the wires are thermocouple wires used to sense temperature in an internal combustion engine while the spark plug is in use. The methods and tooling may result in channels that are formed more precisely, economically, and efficiently.

Abstract: A spark plug has a shell, an insulator, a center electrode, a ground electrode, and a firing pad. The firing pad is made of a precious metal material and is attached to the ground electrode. The firing pad has a side surface at a peripheral edge that can be flush or nearly flush with a free end surface of the ground electrode. This construction can help improve ignitability and flame kernel growth of the spark plug during a sparking event, and can provide better thermal management at the attached ground electrode and firing pad.

Abstract: A method of manufacturing an electrode material for use in spark plugs and other ignition devices. The electrode material may be manufactured into a desirable form by hot-forming a layered structure that includes a ruthenium-based material core, an iridium-based interlayer disposed over an exterior surface of the ruthenium-based material core, and a nickel-based cladding disposed over an exterior surface of the iridium-based material interlayer. The elongated layered wire produced by the hot-forming then has its nickel-based cladding removed to derive an elongated electrode material wire that includes the ruthenium-based material core encased in the iridium-based material. The elongated electrode material wire can be used to make many different spark plug/ignition device components.

Abstract: A corona ignition system including a corona igniter, an energy supply, and a frequency detector is provided. The energy supply provides energy to the corona igniter during corona events which are spaced from one another by idle periods, during which no energy is provided to the corona igniter. During the idle periods, the frequency detector obtains the resonant frequency of the corona igniter from at least one of an output voltage and an output current of the energy stored in the corona igniter. The resonant frequency measured during this idle period is dependent only on the corona igniter, and not any other components of the system, and thus is very accurate. The drive frequency of future corona events can then be set based on this accurately measured resonant frequency to achieve a robust corona discharge.
