ABSTRACT:
Electronically controlled internal combustion engines are operated based upon control calibration algorithms that can come in a variety of forms, including maps, equations, surfaces and other mathematical techniques. Each combination of a control calibration algorithm and a particular engine must satisfy certain constraints such as customer acceptance and value demands, and should have the ability to perform a variety of expected duty cycles for the given engine application. A plurality of different engine control calibration algorithms are made available to an engine control system. Each of the engine calibration algorithms corresponds to a particular duty cycle while being optimized for a performance parameter such as reduced emissions, while meeting a variety of constraints.
