| 초록 |
In the GDI engines, the spray characteristics of injector have strong influence on the engine performance and emissions. In this experimental investigation, the spray characteristics of three kinds of commercial injectors equipped in the present GDI engines were analyzed. Experiments were performed at 1, 3, 5, and 9MPa of injection pressure under the atomspheric condition. To specify the characteristics of spray atomization, the PDPA system was used, and it was employed that the visualization system to measure the spray penetration and angle. |
