Abstract:
Systems and methods for operating an engine of a vehicle during high engine loads are presented. In one example, fuel may be conserved at higher driver demand torques by limiting engine torque when the engine is operated in an economy mode. Additionally, two accelerator pedal position based fuel enrichment schedules are provided for operating the engine in different operating modes.
