摘要： A method for drying a seal material for use in manufacturing an ignition device, e.g., a spark plug. A free-flowing or loose seal material having a moisture content is provided and brought together with a desiccant for a time sufficient to produce a dry seal material by reducing the moisture content of the loose seal material to a desired level. Thereafter, the dry seal material and the desiccant may be separated from one another so that the dry seal material can be used to form a seal within an internal bore of a spark plug.

摘要： An industrial spark plug (20) includes a central electrode (24) with a central base (30) formed of a nickel-based material and a central firing tip (32) formed of an iridium-based material. The central firing tip (32) has a tip thickness (tct) of 0.02 to 0.03 inches, a tip diameter (dct) of 0.1184 to 0.1776 inches, and an aspect ratio of 4.736 to 7.104. The central firing tip (32) is electron beam welded to the central base (30) to provide a robust joint therebetween. The central electron beam weld (36) includes a mixture of re-crystallized iridium-based material and re-crystallized nickel-based material extending continuously along and over the entire welding interface. The spark plug (20) also includes a ground electrode (26) with a ground firing tip (38) electron beam welded to a ground base (42).

摘要： A corona discharge ignition system comprising a plurality of corona igniters is provided. The system includes a control and drive electronics unit for directing the energy from a power supply toward the corona igniters; and a single transformer disposed between the control and drive electronics unit and the plurality of corona igniters. A plurality of igniter switching units is connected to the control and drive electronics unit and each igniter switching unit is connected to a separate one of the corona igniters. Each igniter switching unit allows current to travel from the transformer to the one connected corona igniter when activated and prevents current from traveling from the transformer to the one connected corona igniter and from the one connected corona igniter toward the transformer when deactivated. Only one of the igniter switching units is activated at any given time during operation of the system.

摘要： 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.

摘要： 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.

摘要： 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.
