| Abstract: | The air-fuel-ratio control system of single gaseous automotive engine is analyzed and researched.The PI controller is designed.The correlative simulation and experiment are developed.Through regulating the gaseous fuel supply,the controller can help the engine acquire optimum performance.Air-fuel-ratio can be kept at the stoiclinometric value by closed loop controller in this system.When the circumstance and temperature changed or the engine aged after long-time running,the good performance of controller can be preserved. |
