Operations support systems and methods for calculating and evaluating engine emissions

A method for supporting operations of an engine, comprising:

• collecting engine data;
• generating condition indicators from the engine data using a thermodynamic model based on component maps associated with the engine;
• generating emissions information of the engine from the condition indicators;
• and
• displaying the emissions information on a graphical user display.

An operations support system for an engine, comprising:

• a diagnostics unit configured to receive engine data from the engine and to generate condition indicators based on the engine data using a thermodynamic model, the thermodynamic model being based on component maps associated with the engine;
• an emissions calculation unit coupled to the diagnostic unit and configured to calculate emissions information for the engine based on the condition indicators;
• and
• a GPS unit configured to determine a location of the engine;
• an emissions limit unit configured to determine emissions standards associated with the engine;
• and
• a graphical user interface coupled to the emissions calculation unit, the GPS unit, and the emissions limit unit and configured to display the emissions information as a function of the location and the emissions standards.
