| 摘 要： | 分析两种改进方法对减少某中速主柴油机的NOx排放的效果,根据IMO推荐的试验程序进行NOx排放测试,测得排放的数据,使用根据IMO的计算方法开发的计算程序进行NOx排放值的计算,并对改进前后的排放结果进行对比,结果证明,只改变喷油提前角虽然能降低排放但牺牲了较大的经济性。

| Abstract: | The effects of NOx emission of two kinds of conversions were evaluated for one medium speed marine diesel main engine. The NOx emission was measured according to the test program recommended by IMO. The emission was calculated by using the self-developed software. Comparing with the data showed that only changing the injection timing can reduce the NOx e- mission with the worse economical efficiency. |
