Abstract
An apparatus that includes a calibration module, a conditions module, and an output module. The calibration module includes a plurality of calibration tables that includes a top-rated torque curve and bottom-rated torque curve for each of a plurality of predetermined engine operating modes of an engine emissions family. The top-rated torque curve corresponds to a top horsepower rating of the engine emissions family and the bottom-rated torque curve corresponds to a bottom horsepower rating of the engine emissions family. The conditions module is configured to determine operating conditions of the internal combustion engine. The output module is configured to command at least one component of the engine to achieve a desired engine output exhaust gas emissions value based at least partially on the operating conditions of the internal combustion engine and a comparison between the top horsepower rating and bottom horsepower rating of the engine emissions family.
