EFI system has severe problems of heavy HC emission generated by large fuel droplets and non-uniform air-fuel mixture. Therefore, various atomization techniques are being developed in order to reduce HC emission. The one among those techniques is air shrouded injector, which has better atomization ability and demands less power loss than other atomizers. Thus, the development of this air shrouded injector can be major topic to cope with international emission regulation. Nevertheless, there are few domestic and foreign studies which deal with air shrouded injector. In this study, the spray characteristics and atomization mechanism of the representative air shrouded injector were analyzed using PDPA system. From experimental results, the definite standards of air shrouded injector's spray characteristics were established. |
