IGNITION SYSTEM FOR INTERNAL COMBUSTION ENGINE AND METHOD FOR INSTALLATION OF SAME

摘要

A novel method and apparatus useful for the installation of a flame cone within a respective throughbore in the head of an ICE having a pre-ignition system without removal of the head from the ICE, followed by threading a spark plug into the outboard end of the flame cone. This installation is effected from a location external of the head and while the head is affixed in covering relationship to one or more combustion chambers of the internal combustion engine. The installation further comprises employing unique interconnection between the flame cone and an installation tool. The flame cone includes a rotational position indicator which is aligned with an exit port in the flame cone and which contributes to the exclusivity of mating interconnection with the tool in a manner which converts rotational movements of the tool to like rotational movements of the flame cone, hence like rotation of the location of the exit port.
