Abstract :
This paper describes the structure of fuel supply system for LPG engines. Based on the method of grey forecasting, the air-fuel ratio of the engine is controlled. Furthermore, the model of back-propagation network is established and the exhaust gas recirculation (EGR) flow rate is controlled. The experimental results show that this control system improves the performance, fuel economy and emissions of LPG engines.
