gas fuel engines electronically controlled injection devices flow characteristics numerical simulation
To describe the flow characteristics of an electronically controlled gas fuel injection device for heavy-duty engine and the relationship between fuel mass and injection duration,numerical simulation models are created.The static and transient flow characteristics are calculated.Experimental validation is also done.The results show that the flow characteristics can be impacted by main design and control parameters such as maximum valve lift,valve diameters,pressure differences,and valve open durations.The influencing rules of different parameters on flow characteristics are also analyzed,which lays a good foundation for the gas fuel electronically controlled injection device’s engineering application.
