스파크 점화기관의 사이클 분석코드의 난류연소모델 비교 및 검증에 관한 연구

Quasi-dimensional analysis is performed to predict the cylinder pressure with respect to the parameters of the intake manifold pressure. spark timing and equivalence ratio. Three combustion models. Turbulent Entrainment Model(FM). FractaJ ModeHFM) and General Engine SImulation Model(GESIM) are implemented to compare the results with experimental data for a .1-cylinder spark ignition engine. Results show that it is possible to follow the qualitative trend although with some discrepancy quantitatively. The flame kernel growth and turbulence prediction/flame propagation model turned out to be the area for further research efforts
