摘　　要：本文对Ｄ６１１４Ｂ型船用柴油机进行基于一维非定常流动的仿真,并且将实验数据与仿真计算参数值进行了对比;在此基础上,对发动机性能进行了预测,并对进排气门正时、压缩比、供油提前角等参数做了优化计算,使其满足高速船用柴油机的特性要求。In this paper, performance simulation based on one-dimension unsteady flow model is conducted for D6114Bmarine diesel engine, and the simulated results compared with the experimenal data. On this basis, performance predictionof the engine is carried out, and optimization of such parameters as inlet/exhaust valves timing, compression ratio andinjection timing is fulfilled so as to meet the special requirements demandd by high speed marine diesel engines.
