摘要： A control system includes an engine speed control module, a fuel control module, and an air control module. The engine speed control module controls an actual speed of an engine based a desired power to be generated by combustion in the engine, wherein the desired power is a product of a desired speed of the engine and a desired torque output of the engine. When operating in a fuel lead mode, the fuel control module controls fuel flow in the engine by adjusting a desired fuel mass for each activated cylinder of the engine based on the desired power. The air control module controls air flow in the engine based on an actual air/fuel ratio of the engine resulting from the desired fuel mass.
