Abstract
Operating a gaseous fuel engine includes injecting a pilot charge directly into a combustion chamber in an engine, and igniting one spray plume of the pilot charge. A flame front is propagated to other pilot spray plumes to produce an ignition flame for igniting later injected main charge spray plumes. Injection of the pilot and main charges is by way of the same fuel injection orifices.
