Abstract:
1. An ignition system for an internal combustion engine comprising: at least one combustion chamber and a fuel injector for introducing a main fuel charge into said combustion chamber; a housing defined in the cylinder head of the internal combustion engine, said housing defining a pre-chamber; an ignition device supported in said housing and having an igniter portion that substantially faces said pre-chamber; an injector supported in said housing and having a nozzle that substantially faces said pre-chamber; said pre-chamber defining a proximal portion and a pre-chamber nozzle disposed spaced from said proximal portion of said pre-chamber, said pre-chamber nozzle including a plurality of orifices disposed spaced from one another and providing fluid communication between said pre-chamber and the combustion chamber; said igniter portion of said ignition device and said nozzle of said injector operatively supported in the proximal portion of the pre-chamber and disposed flush therewith such that said injector delivers a predetermined quantity of fuel into said pre-chamber, said igniter portion ignites the fuel in said pre-chamber such that the ignited fuel is forced through said orifices of said pre-chamber nozzle and extinguished at said nozzle, but dispersed through the combustion chamber so as to ignite the main fuel charge therein.
