Abstract:
A compression increasing spark plug comprising:an elongated insulator;an elongated electrode extending longitudinally through a center of said insulator with ends of said elongated electrode being exposed at a lower end and an upper end of said insulator;a body surrounding a lower portion of said insulator, said body having an extended threaded section about said body; an extended nose at a lower end of said extended threaded section; and a second electrode at an end of said extended nose, said lower end of said insulator and a lower end of said elongated electrode being exposed at a lower end opening in said extended nose, such that an electric spark can jump or short across a gap between said lower end of said elongated electrode and said second electrode; anda pair of locking nuts on said extended threaded section, said locking nuts being adjustable on said extended threaded section for determining how deep said extended threaded section and said extended nose extend into a combustion chamber of an engine, and said locking nuts being tightened against each other to lock said locking nuts in a position on said extended threaded section.
