  "textContent": "Operating a gaseous fuel engine system includes urging a mixture containing a gaseous hydrogen fuel and air into a pocket in an igniter fluidly connected to a cylinder to form an ignition charge, and igniting the ignition charge via a flame kernel formed by energizing spark electrodes of the igniter. The method further includes igniting a main charge containing the gaseous hydrogen fuel via a flame jet of the ignition charge from the igniter. The pocket is shielded from the cylinder sufficiently to form within the pocket a flow field protecting the flame kernel, while fluidly connected to the cylinder sufficiently to clear the pocket of residual combustion gases.",
