Spray Characteristics of the Air-Shrouded Injectors
초록
Improving the atomization characteristics by adopting the Air-Shrouded injector has been considered as one of the important methods for decreasing HC emissions in SI engines. Thus, in this study for the purpose of developing Air-Shrouded injector which has a finer spray, atomization characteristics of different types of commercial Air-Shrouded injectors were investigated through the spray imaging and the drop size measurements. As a result, it was found that the internal mixing type of Air-shrouded injector had a good atomization characteristics. But, a number of large droplets were found in the internal mixing type commercial injector, this phenomenon was improved by adopting the thread type nozzle passages.
