Intelligent control study of engine air-fuel ratio co-simulation based on information fusion

The multi-sensor information fusion technology is briefly introduced in the article. The basic structure of air-fuel ratio control system with information fusion is discussed by combining the function and characteristics of air-fuel ratio control system of gasoline engine transient condition. The information fusion model of air-fuel ratio control of gasoline engine transient condition is proposed by combining information fusion function with the air-fuel ratio control. The air-fuel ratio of gasoline engine has been precisely controlled when information fusion model used in the co-simulation model of gasoline engine. Simulation results show that air-fuel ratio can be controlled at around 14.7 when using the information fusion technology and it can meet the emission requirements for air-fuel ratio.
