摘 要：Parameters are obtained by mapping the entity structural electronic control unit pump injection system of HXn5 diesel locomotive introduced from USA.A simulation model was built up with GT-Fuel,which can well reflect the electromagnetic and hydraulic characteristics of the fuel injection system,as well as the fuel injection rate and fuel quantity.Compares with locally high-power diesel,the calculation curves show its superiority,which will establish a foundation for optimization and improvement of local fuel injection system.
