MPI 인젝터의 분무 및 미립화 특성에 관한 연구

Mixture formation is one of the important factors to improve combustion performance of an spark ignition engine. This is affected by spray and atomization characteristics of injector. In this paper, spray characteristics such as size distributions, SMD, spray angle, and velosity are measured by PMAS. Atomization levels are investigated with developed various air-assisted injectors. From these experiments, spray patterns and atomization characteristics injected from MPI injector are made clear. And these results revealed a design guide for air-assisted injector.
