Abstract
A computer system includes a processor and a memory configured with instructions executable by the processor to determine a fuel configuration in response to input received by the HMI, determine fuel composition constituents in response to at least the fuel configuration, determine one or more fuel properties in response to at least one or more fuel composition constituents, determine one or more engine controller adjustments in response to the one or more fuel properties, and provide the one or more adjustments to an engine control system. A human-machine interface (HMI) is operatively coupled with the processor, and a memory and may be utilized to provide commissioning or service inputs.
Claims21
A computer system comprising:
- a processor configured to receive input from a human-machine interface (HMI);
- and
- a non-transitory memory medium in operative communication with the processor and configured with instructions executable by the processor to perform the acts of:
- determining fuel composition constituents, the fuel composition constituents indicating an amount of at least one of a plurality of molecules,
- determining one or more fuel properties in response to one or more fuel composition constituents, the one or more fuel properties indicating at least one physical property of the at least one of the plurality of molecules,
- determining one or more engine controller adjustments in response to at least one of the fuel composition constituents and the one or more fuel properties, the one or more engine controller adjustments adjusting at least one of a control command and a sensed value utilized in controlling an engine, and
- providing the one or more engine controller adjustments to an engine control system;
- wherein the one or more fuel properties comprise a gas constant and a ratio of specific heats of the fuel composition constituents, and the one or more engine controller adjustments comprises an adjustment to a fuel control valve command which controls the admission of gaseous fuel to the engine and which are determined in response to the gas constant and the ratio of specific heats.
A process comprising:
