某发动机排气系统CAE分析 Introduction Engineperformanceandefficiencydependonseveralfactorsthatplayavitalroleinoptimizingtheoverallperformance.Oneofthemostcrucialcomponentsistheexhaustsystemthatisresponsibleforcarryingouttheexhaustgasesafterthecombustionprocess.TheCAE(Computer-AidedEngineering)analysisoftheexhaustsystemprovidesaquickandefficientwaytoanalyzetheperformanceandeffectivenessofthesystem.Inthispaper,wewilldiscusstheCAEanalysisoftheexhaustsystemanditssignificanceinoptimizingengineperformance.
