Abstract: 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.

Abstract: Method and apparatus useful in simultaneously enhancing the fuel consumption efficiency of an ICE, with concomitant enhancement of the power delivered by the engine, and reduction of undesirable exhaust emissions. One embodiment of the method of this invention includes the steps of introducing a fuel/air mixture to the main combustion chamber of the ICE, providing a flame front pre-combustion system which enhances the timely delivery of multiple flame fronts to specific locations within the main combustion chamber for substantial spontaneity of ignition and combustion of the fuel/air mixture disposed within the combustion chamber when the crankshaft is within about 5 degrees nearer top dead center (TDC) than the timing established by a standard operation map for the ICE in question and which employs a conventional spark plug disposed within the combustion chamber. Such combustion continues over that time period during which the crankshaft travels at least past TDC and into its power stroke.

Abstract: Method for installation and functioning of a flame front type ignition system in the conventional throughbore through the wall of the head of an internal combustion engine. 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. In one embodiment, there is employed a flame cone which is threadably inserted within the throughbore proximate the inboard end of the throughbore. The inboard end of the flame cone is provided with a plurality of exit ports opening from a first central channel within the flame cone thence into the combustion chamber along preselected paths. The flame cone is provided with one or more alpha letters on the outboard face of the flame cone where they are visible to a person threading the flame cone into the throughbore. Further, a marker (e.g. an arrow) is provided on the outer rim of the throughbore.
