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: A method and apparatus for installation and functioning of a flame front type ignition system in a throughbore through the wall of the head of an internal combustion engine. The flame front ignition system employs a flame cone which is thread ably inserted within the throughbore. The inboard end of the flame cone is provided with a plurality of exit ports opening from a central channel and into the combustion chamber. The flame cone is provided with indicia on its outboard face and a marker is provided on the outer rim of the throughbore. When an indicia letter on the flame cone is aligned with the marker, the flame cone is properly installed. The depth of insertion of the flame cone is adjustable by means of spacer washers adapted to selectively adjust the dept as well as seal the flame cone in the throughbore.

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.

Abstract: A multi-part module including a flame cone and a connector adapted to be interposed between the normal spark plug port in an internal combustion engine block and a spark plug suitable for use with the engine in question. In the method, a quantity of fuel/air mixture is captured in a chamber which also houses the electrode of a spark plug. Upon generation of a spark from the spark plug, this quantity of fuel/air mixture ignites, generating a flame which propagates through one or more channels in a flame cone interposed between the spark plug and the cylinder of the engine and exits into the cylinder through multiple directionally oriented ports, whereupon the flame fronts rapidly ignite substantially all the fuel/air mixture held within the cylinder.
