摘　　要：某车用柴油机改型为船用 ,排气管相应地由风冷改成水冷。本文对原机进行了模拟计算和实验校核。在此基础上 ,对改用水冷单排气总管的机型进行模拟计算 ,对排气管结构 ,进、排气阀正时对柴油机运行的影响进行了分析。实验研究表明 :采用单排气总管增压系统 ,新的机型能够满足功率要求 ,在低工况下燃油经济性也较好。A vehicle engine was remodeled for marine use,and accordingly,it's air-cooled exhaust manifold is changed to a water-cooled one.In this paper,the analogy computation and experimental investigation on the original engine was carried out,based on which,the performance of the remodeled one adopting a single exhaust manifold turbocharged system was calculated.Further experiments show that the power of the remodeled engine is acceptable and the fuel efficiency under low load is good.
