8NVD48A-2u柴油机性能改进研究

Study on performance improvement of the 8NVD48A-2u diesel engine

针对某船柴油主机热负荷过高的问题进行了理论分析和实验研究 ,提出增装空气中冷器和增强海水冷却能力的措施 ,实践证明 :该方法可以大大降低柴油机的热负荷 。

The theoretical analysis and experimental research are performed in order to resolve the problems of the high thermal load of marine diesel engine. It is supposed to install an intermediate air cooler and enhance cooling ability by sea water. It is shown in practice, that the method is ablate considerably decrease thermal load of diesel and improve its performance.
