船用柴油机NOx排放测试有关参数的调整与分析

Parameter adjustment and analysis on measurement of NOxemission of marine diesel engine

简要介绍船用柴油机排放中主要污染物NOx的排放限值,从喷油定时和最高允许海水温度两个参数了解其对排放测试的影响,分析结果,得出对其控制的试验依据。

This paper introduces briefly the restrict value of the main exhaust NOx emission from marine diesel engine, analyzes the influence of injecting time and maximum seawater temperature upon the measurement of the exhaust emission, and get the test basis to control these 2 parameters.
