Abstract: An internal combustion engine system is described herein. The system uses reactor to create pilot fuel from the primary fuel to assist in the ignition of the primary fuel. A controller is used to maintain an operational range of a level of the pilot fuel in an accumulator. The accumulator acts as a buffer to allow the engine to continue to receive the pilot fuel during dynamic and changing conditions of the engine. The controller increases or decreases the rate of production of the pilot fuel by a pilot fuel system to maintain the operational range of the level of the pilot fuel in the accumulator. The controller can receive inputs such as pilot fuel level or power signals from the engine to adjust the rate of production of the pilot fuel to meet engine demand.
