Experimental Research on Dual-fuel Engine with Single ECU

LI Jing-bo

Abstract

To improve the performance of compressed natural gas(CNG) engine,the gas supply system of CNG/gasoline dual-fuel engine with a single electronic control unit(ECU) was designed,the control strategies for air/fuel ratio,density compensation and fuel switching were studied and the bench and vehicle tests were carried out.The results show that the dual-fuel engine with a single ECU excels the dual-fuel engine with the master-slave control ECU.
