ABSTRACT:
A spark plug for use in a combustion engine, which includes a spark plug body defining a central cavity; a electrode disposed within the cavity; a spring means disposed in one end portion of the central cavity; and a plate means operatively associated at one end with the spring means and adapted to communicate at its other end with the electrode whereby when the engine starts, the respective compression and explosion strokes move the plate means in one direction against the bias of the spring and in the opposite direction by the force of the spring, which in turn moves the other end of the plate in communication with the electrode in the same manner whereby combustion carbon collected on the electrode can be effectively removed.
