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.

System and method for testing breakdown voltage/dielectric strength of spark plug insulators

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 further includes 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.

An igniter for an internal combustion engine includes a center electrode, an insulator disposed about the center electrode, and a ground shield or a threaded portion disposed about the insulator, wherein the insulator includes a tip portion extending past an end portion of the ground shield and a tip portion of the center electrode extending through and away from the tip portion of the insulator. The igniter further includes a cap secured to the center electrode, wherein the cap extends past and covers a distal end of the tip portion of the center electrode and a distal end of the tip portion of the insulator. A spark gap is disposed between a peripheral edge of the cap and the end portion of the ground shield or threaded portion wherein the peripheral edge of the cap is spaced away from a surface of the tip portion of the insulator.
