Beschreibung
Zusammenfassung:	A cycle-by-cycle skip-fire fuel-injection technique for pilot-ignited engines involve skip-firing selected combustion chambers when a low load condition is determined and modulating the fuel delivery to maintain the requisite engine power, while reducing pilot fuel quantity to a predetermined minimum. Overall pilot fuel consumption is thereby reduced.
