Systems and methods for using pedal position and/or pedal change rate in the fuel side and/or air side control of an engine. By knowing the pedal position and/or pedal rate, an engine controller may anticipate future fuel and/or air needs of the engine, and adjust the fuel profile and/or air profile
Systems and methods for using pedal position and/or pedal change rate in the fuel side and/or air side control of an engine. By knowing the pedal position and/or pedal rate, an engine controller may anticipate future fuel and/or air needs of the engine, and adjust the fuel profile and/or air profile to meet those anticipated needs. This may help improve the responsiveness, performance and emissions of the engine.
