Abstract
A method for delivering liquid fuel and gaseous fuel to a dual fuel engine operating in a dual fuel mode includes establishing a governor output value indicative of a total fuel energy rate desired to be delivered to the engine to maintain a desired engine speed. A first value indicative of a liquid pilot fuel energy rate desired to be delivered to the engine and a second value indicative of a gaseous fuel energy rate desired to be delivered to the engine are each determined such that the sum of the desired liquid pilot fuel energy rate and the desired gaseous fuel energy rate is substantially equal to the desired total fuel energy. A stored gaseous fuel energy content can be updated to assure continued accuracy of the fuel control system of the dual fuel engine.
