MPI 가솔린 기관의 분무 및 벽류 거동 특성에 관한 연구

Mixture formation is affected by spray characteristics of injector and wall film flow. In this paper, spray characteristics such as size distribution, SMD, spray angle and velocity of three type injectors which have different spray patterns are measured by PMAS. Wall film flow rate of intake port are measured. From these experiments, the fuel behavior of three type injectors such as injection direction, spray angle and wall film flow is made clear. Consequently, the optimal fuel injection system and conditions for reducing spray size and minimizing the wall fuel film are found through this research.
