기상분사용 LPG 기화기의 유량 및 압력특성에 대한 실험적 연구

다국어 초록 (Multilingual Abstract)

In order to satisfy more stringent emission regulations, it is required to control the fuel supply system with higher accuracy for LPG vehicles. Vaporizer, which is one of the important core parts in gaseous LPG injection system, functions not only to evaporate an LPG fuel and its pressure. thus in this work, pressure drop across the vaporizer in a gaseous LPG vehicle was measured and analyzed. Pressure drop occurs through orifices of pressure regulator and flow meter. As expected, pressure drop depends on flow rate, which increases when the more fuel is needed to be injected. Although Pressure sensor helps engine computer calculate the accurate amount of injected fuel depending on fuel pressure, it may be necessary to understand the pressure drop as a function of flow rate and coolant temperature. In this work, an experimental study of flow rate and pressure drop across the vaporizer was carried out.
