建立了D683ZLCA9B柴油机燃烧模型,应用STAR-CD软件分别对平原环境和4250m下缸内的燃烧过程进行了数值模拟研究。平原环境下,计算结果与试验结果吻合较好。高原环境下,得出不同负荷对柴油机性能的影响情况。该研究可为设计或改进高原地区使用的柴油机提供参考。
The D683ZLCA9B diesel combustion model was established and the combustion process in the plain environment and 4250m cylinder was simulated by STAR-CD software respectively. In the plain environment, the calculated results are in good agreement with the experimental results. High altitude environment, come to different load on diesel engine performance. This study can provide reference for designing or improving the diesel engines used in the plateau.
