摘要
应用AVL FIRE软件,对k系数喷油嘴进行了三维流动计算,并在CA4DC2柴油机上进行了k=1.5和k=0喷油嘴的对比试验研究,试验结果表明:k=1.5系数喷油嘴全面改善了柴油机的性能指标。
Three dimensional simulations were made for K-coefficient nozzle by means of AVL FIRE software. Comparative experiments of nozzles of k=1.5 and k=0 were carried out on CA4DC2 Engine. It was found that the engine performance was overall improved with the nozzle of k = 1.5.
