摘　　要：设计了一套船舶柴油机冷EGR系统,并对其控制系统进行了软件和硬件的设计,控制部分通过单片机控制伺服水泵的转速来调节冷却水的循环量,保证不同工况下的最佳EGR冷却温度,在船舶柴油机YC4F90L-C20上进行了试验,结果表明,与无EGR系统相比,该自控冷EGR系统在CO和HC的排放基本不变的情况下,可以有效的降低NOx的排放和烟度,保护了海洋环境。This paper designs an auto-control cooled system and makes the software and hardware designs for. its control system to control the rotating speed of Single Chip Micyoco servo pump, in order to regulate the cooled water circulation, which ensures the optimum EGR cooling temperature,By applying this system to YC4F90L-C20 diesel engine,the test result shows that compared with no EGR system,the control system can not only be used to effectively reduce the NOx,smoke, but also almost keep the CO and HC same emission quantity. Thus the marine environment is protected.
