[가솔린엔진] 공기 보조 미립화 인젝터의 미립화 및 벽류 생성 특성에 관한 연구

EGI system has severe problem that heavy HC emission is generated due to large fuel droplet and fuel film attachment. Therefore. for the purpose of reducing HC emission. various atomization techniques is being developed. The one among those techniques is air shrouded injector. which has better atomization ability and demand less power loss than other atomizers. In this study, using Malvern system and fuel film measurement device, the atomization and fuel film characteristics of an air shrouded injector was analyzed, and design factors to develop air shrouded injector was established.
