LNG 엔진에서 당량비와 점화시기에 따른 엔진의 성능과 배기 특성에 관한 수치 해석적 연구

Abstract

In this research, engine performance and emission variation according to equivalence ratio and ignition time is calculated by validated analysis model. LNG engine ignite by spark plug and spark ignition modeled using DPIK model and G-equation that modeled initial flame surface called kernel and velocity and position of flame front. Engine pressure and emission was validated with experimental data.
