Simulation Research on Matching Parameters of Injector in Diesel Engine Based on Field Effect Analysis Method

To match parameters of fuel injection system on 1132Z diesel engine, field effect analysis method was used. Numerical simulation was conducted and the influence of fuel spray angle, nozzle diameter, number of injection holes on process of mixing and atomization was quantitatively analyzed. The optimized injector parameters were obtained. The result shows that the computation method based on field effect analysis could be used as a guidance to match the fuel injection system of diesel engine.
