ABSTRACT:
An engine control system for controlling engine operation in high-output (HO) and fuel-economy (FE) modes in a gasoline direct injection (GDI) engine includes an alternator that is driven by the engine and that is regulated by a load control signal. An alternator load control module generates the load control signal based on an engine torque to regulate a load of the alternator on the engine to maintain the engine torque below a threshold level and maintain engine operation in the FE mode.
