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.
