某柴油机进气歧管废气均匀性分析及优化设计

Analysis and optimization design of exhaust manifold uniformity of diesel engine intake manifold

利用三维CFD软件模拟某柴油机进气歧管废气均匀性，计算得到各个气缸的EGR率和EGR率差异性，并对优化后方案再次进行CFD分析。

In this paper; we use the CFD software to simulate the uniformity of the exhaust manifold of a diesel engine, calculate the EGR rate and the EGR rate difference of each cylinder, and then make a CFD analysis of the optimized scheme.
