Electronic control system for gasoline automotive engine: state of the art and perspective

As the core research field in the development of high performance and high reliability vehicle engine, the electronic control system is one of the key factors for satisfying the engine performance of power, fuel economy and emissions. The typical structure of the electronic control system of gasoline engine is analyzed firstly. Then, the control technology and theory of gasoline engine electronic control system are reviewed from eight aspects: electronic throttle control, fuel injection control, ignition control, air-fuel ratio control, idle speed control, turbocharging control, knock detection and control and combustion control, where the state of the art of the engine electronic control technology are introduced as a key point. Finally, the prospects for the development of spark ignition engine electronic control system are presented.
