Abstract
An engine--powertrain--controller combination includes a microprocessor control unit which predicts a future value of an engine state and uses that predicted value in engine control functions for improved control of the engine--powertrain in such areas as air-fuel ratio control, control of the engine during engine idle, and engine spark timing control.
