    Abstract: A sparkplug assembly having a prechamber volume is operatively associated with the combustion chamber of an internal combustion engine such that the prechamber volume is in fluid communication with the combustion chamber. To purge exhaust gasses from the prechamber volume prior to ignition, the sparkplug assembly is operatively associated with a high-pressure air/fuel source that directs a pressurized air/fuel purge charge to the prechamber volume. The pressurized air/fuel purge charge may be at stoichiometric conditions. The high-pressure air/fuel source is configured to direct the pressurized air/fuel purge charge during at least a portion of the compression stroke to maintain a largely stoichiometric mixture of air and fuel in the prechamber volume.

    Abstract: A nozzle for a prechamber assembly of an engine includes a nozzle body. The nozzle body is hollow and includes an outer surface and an inner surface. The outer surface defines an outer opening, and the inner surface defines an interior chamber and an inner opening. The nozzle body includes an orifice surface which defines an orifice passage extending between, and in communication with, the outer and inner openings. The orifice passage is in communication with the interior chamber via the inner opening. The orifice surface is continuously curved. The inner surface of the nozzle body can include a groove surface that is contiguous with the orifice surface. The groove surface defines an orifice groove in communication with the interior chamber and with the orifice passage.

    Abstract: Systems and methods for operating an engine include controlling a temperature of recirculated exhaust gas to achieve a predetermined recirculated exhaust gas temperature. A mixture of air and temperature-controlled recirculated exhaust gas are admitted in a combustion chamber and a gaseous fuel injector delivers gaseous fuel during an intake stroke. A diesel fuel injector is activated for a first time to deliver a pre-pilot diesel quantity directly into the combustion chamber at an early stage of a compression stroke, and is activated again for a second time to deliver a pilot diesel quantity directly into the combustion chamber at a later stage of the compression stroke. A total air/fuel ratio within the combustion chamber upon completion of the second diesel fuel injector activation is lean. The air/fuel mixture is combusted during a combustion stroke, and combustion products are removed during an exhaust stroke.
