    Abstract: A method of applying a coating to a spark plug insulator comprises the steps of forming a slurry solution and applying the slurry solution as a first coating to an insulative sleeve configured for use in a spark plug. The method further includes the step of heat treating the insulative sleeve to a temperature of between about 500 degrees Celsius and about 1000 degrees Celsius for between about 10 minutes and about 2 hour(s). Still further, the method includes the step of applying a second coating overlying at least a portion of the first coating, wherein the second coating comprises an organic binder.

    Abstract: A spark plug is provided having a resistor. The resistor is made from resistor glass material containing an alkali free barium alumino-silicate glass mixed with mullite. In one embodiment, the resistor is a 15 to 30 wt % alkali free barium alumino-silicate glass and 10 to 25 wt % mullite. The resistor material provides for a greater processing kiln temperature range with reduced resistor variability and improved durability performance.

    Abstract: A system for testing an insulative material for a spark plug comprises a test spark plug having at least a center electrode and an insulator comprised of an insulative material surrounding at least a portion of the center electrode, wherein the insulator has an end that is closed, whereby the closed end of the insulator encloses an end of the center electrode. The system may further include a test engine that simulates engine conditions, wherein a conventional spark plug is installed in a first ignition port of the test engine and the test spark plug is installed in a second ignition portion of the test engine and a control system for controlling ignition signals to the test spark plug and the conventional spark plug.
