| 摘 要： | 通过对东京水产大学研究练习船“神鹰丸”的航速、主机转速、功率及排放废气的测定，得出在各种常用工况下NOx的排放率曲线、等船速曲线和燃油消耗率曲线。分析比较确定NOx的排出率较低，燃油消耗率又不超过规定标准的工况点，从而达到主机优化操纵的目的。结果表明，在自由航行工况下船舶航速为4、8、12、13kn时，主机转速应设定在750r/min；航速为10kn时，应设定在875r/min。拖网及延绳钓作业工况下主机转速应设定在875r/min。

| Abstract: | The curves of the NO x emission,the equal ship speed and the specific fuel consumption in various conditions were obtained by measuring the main engine speed, the output and exhaust gases of the fishing study exercise ship SHINYO MARRU of Tokyo University of Fisheries. The paper obtained the points of lower NO X emission and the specific fuel consumption by comparing and analyzing the operation of the main engine by optimization. The results are: Under sailing condition, the main engine speed should be set at 750rpm when the ship speeds are 4,8,12 and 13kn; The main engine speed should be set at 875r/min when the ship speed is 10kn or while in fishing operation (trawl fishing and tuna long line fishing) |
