摘　　要：综述了内燃机进排气系统气体流动模拟计算的现状与趋势 ,简要介绍了容积法、特征线法及有限容积法 ,重点介绍了这一领域的最新技术——时空守恒元和解元方法 ( CE- SE)。The Present status and trend of numerical simulation for inlet and exhaust system of IC engines are summarised. A brief introduction about the simulation methods such as the filling and emptying, the characteristics and the finite volume have been given with the emphasis on the Conservation Element Solution Element(CE SE) which is the most advanced technique.
