- Abstract
- The spray characteristics of DISI injector has a great role in engine efficiency and emission. Thus, many researchers have been studied to investigate the spray characteristics of hollow cone type and slit type injector which are used in DISI engine. In this study, we tried to provide spray parameters which effect on the spray characteristics such as injection pressure, ambient pressure and ambient temperature. In addition, we calculated tb and tc to investigate the break up mechanism of test injectors and also obtained Cv to evaluate the spray characteristics. From this study, As the ambient pressure increases in case of slit injector, Cv decreases.
