| Abstract:Operation principles and characteristics of a new type common rail injector are introduced. Its numerical model was built based on AMESim software. 5 non-dimensional parameters was set to analyze their effects on injector’s performance. Orthogonal array was used to estimate the degree of influence caused by each parameter, and the optimized structure parameters are obtained, which could be a design reference for injector parameters trade-off in the future. |
