Abstract
Operating an internal combustion engine system includes advancing a prechamber piston in a fuel delivery igniter to push a main charge of fuel from a prechamber into a cylinder, and advancing the prechamber piston to compression-ignite a pilot charge within the prechamber. Combustion gases of the pilot charge are conveyed into the cylinder to ignite the main charge. Operation of the engine system provides sparkless gaseous fuel ignition.
