Patent ID: 8833052

Claim:
A method for controlling fuel mixing, the method comprising: identifying one or more parameters associated with the operation of a machine, wherein the machine is configured to receive a combined fuel formed by mixing together a plurality of fuel types; determining a fuel flow of the combined fuel that is provided to the machine, wherein the fuel flow is determined by a combined fuel flow meter after at least a first fuel type has been added to at least a second fuel type; compressing the combined fuel utilizing at least one compressor; determining, based at least in part on the identified one or more parameters, a ratio of a flow of the first fuel type to the determined fuel flow, wherein the first fuel type has a heating value that is greater than another fuel type of the plurality of fuel types, and wherein the ratio comprises a correction for water dropout after the combined fuel is compressed; setting a flow of the first fuel type based at least in part on the determined ratio; determining an energy content of the fuel flow of the combined fuel subsequent to setting the flow of the first fuel type; and adjusting the flow of the first fuel type based at least in part on the determined energy content, wherein the above are performed by one or more computers associated with a machine controller.
