Abstract
A pressure relieving spark plug for use with an internal combustion engine. The pressure relieving spark plug functions as a conventional spark plug under normal operating conditions; however, upon the development of abnormal conditions, such as excessive combustion chamber pressures or excessive engine temperatures, the spark plug is designed relieve cylinder pressure by one or more venting stages such that damage to the engine is averted. Once actuated to one or more venting stages, the spark plug is resettable to a configuration wherein the spark plug is again capable of functioning as a conventional spark plug.
