摘要： A engine control system and a method of controlling a torque output of an internal combustion engine is disclosed. The engine control system comprises a torque receiving device operably connected to the engine, a sensor to sense an engine parameter, and an electronic device operably connected to the sensor. The electronic sensor is operable to determine a second engine speed from sensed engine parameters, a droop speed, and a selected one of a plurality of torque maps requiring a minimum amount of fuel. The electronic sensor is also operable to transmit a signal indicative of the second engine speed to a fuel system to control the amount of fuel delivered to the engine.
