摘要
进气管结构对发动机各缸进气不均匀性影响很大,继而影响到发动机的性能,通过对天然气发动机进行一三维耦合模型联合仿真,获得了各缸进气不均匀性,为解决发动机各缸性能差异较大的问题指明了方向。
The structure of air-intake duct has great effects on air intake unevenness of each cylinder in engine, so to affect on engine performances. This paper makes an united simulation to air-intake duct-three dimensional coupling model to gain air-intake unevenness of each cylinder, which points out the direction to solve greater performance difference of each cylinder in engine.
