ABSTRACT:
A torch jet spark plug is provided which is suitable for use in a torch jet-assisted spark ignition system for an internal combustion engine. The torch jet spark plug is configured to ignite an air/fuel mixture within a combustion prechamber formed integrally within the body of the spark plug, such that a jet emanates from the prechamber and projects into the main combustion chamber of the engine, so as to enhance the burning rate within the main chamber. More particularly, the spark plug is configured so as to be relatively unsusceptible to pre-ignition, and also substantially eliminates the occurrence of internal short circuits to ground due to deposits accumulating within the prechamber. The spark plug achieves each of the above objects while having a relatively uncomplicated structure, requiring a minimal number of discrete components so as to enhance its manufacturability.
