Patent ID: 8650851

Claim:
A method for controlling fuel flow within a machine, the method comprising: identifying a plurality of fuel types provided simultaneously to the machine; identifying a plurality of fuel circuits associated with the machine, a first group of the plurality of fuel circuits adapted to be provided with one or more of the plurality of fuel types, a second group of the plurality of fuel circuits adapted to be provided with at least two of the plurality of fuel types; identifying a fuel flow parameter for calculating fuel flow comprising at least one of: an energy flow parameter, a volumetric flow parameter, or a fuel constituent flow parameter; calculating a respective energy flow for each of the one or more fuel types provided to each of the plurality of fuel circuits based at least in part on the identified fuel flow parameter, wherein calculating the respective energy flow is initiated by determining a ratio of total energy flow of the machine to the respective energy flow provided to each of the plurality of fuel circuits; and controlling, based at least in part on the calculation of the respective energy flows, operation of one or more fuel flow control devices providing fuel to the plurality of fuel circuits.
