[디젤엔진부문] VCO와 MiniSAC 노즐특성이 Small HSDI 디젤엔진의 성능에 미치는 영향

VCO nozzle was devised to minimize the HC emission and has been applied on some HSDI diesel engines. But it is not well reported whether VCO nozzle would be advantageous over SAC nozzle in a small HSDI diesel engine. In this paper it is presented that characteristics of VCO and SAC nozzle under common rail fuel injection system and their effects on the performance in a small HSDI diesel engine.
