TURBULENT JET IGNITION PRE-CHAMBER COMBUSTION SYSTEM FOR SPARK IGNITION ENGINES

摘要

An ignition system (10) for an internal combustion engine (12) having at least one combustion chamber (22) where the ignition system (10) includes a housing (42), an ignition device (86), an injector (90), and a pre-chamber (50) having a nozzle (78) disposed spaced from the proximal portion (76) of the pre-chamber (50). The igniter portion (88) of the ignition device (86) and the nozzle (92) of the injector (90) are operatively supported in the proximal portion (76) of the pre-chamber (50) and disposed flush therewith. The igniter portion (88) ignites the fuel in pre-chamber (50) such that partially combusted pre-chamber products are forced through orifices (82) in the pre-chamber nozzle (28) and extinguish, but dispersed through the combustion chamber (22) so as to ignite the main fuel charge therein.
