摘要： 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. A datum alpha letter (“A” in the present disclosure) is aligned on the face of the flame cone in a position which, when aligned with the marker on the rim of the throughbore, indicates that the flame cone is at the proper rotational attitude within the throughbore wherein the exit ports in the flame cone are correctly angularly oriented within the throughbore such that flame fronts exiting such ports are also properly aligned relative to those locations within the combustion chamber toward which flame fronts desirably are directed for ignition purposes.The depth of insertion of the flame cone into the throughbore through the wall of the head of the ICE, is adjustable by means of spacer washers adapted to selectively adjust such depth of sealing insertion of the flame cone within the throughbore as a function of the angular orientation of the exit ports for flame fronts entering the combustion chamber of the ICE.Apparatus for carrying out the method is disclosed.

摘要： 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.
