Effects on Locomotive Diesel Engine Performance by Selecting Solenoid Valve Parameters

Feng JIANG, Ming-hai LI, Juan WANG, Yuan-zhe LI


Solenoid valve is the key component to determine the performance of electronic fuel injection system for the diesel engine. By theoretically analyzing the characteristics of solenoid valve driver, we found out that one of the factors that affect the closing & opening speed of solenoid valve is drive current. In this paper, GT-Flow software is used to simulate and analyze the drive current, and come to the optimal combination of current. The selected drive current is used to analyze the emission performance of 16V265H diesel engine, to determine the best advance angle for fuel supply, and to compare the simulation results with the experimental values.
