实际工况下内河航行船舶NOx排放测试与分析
Emission test and analysis of NOx from inland ship under real-world operating modes
摘要
Abstract
Seven inlands ships were tested by using portable emission measurement system (PEMS) to analyze the real-world emission of NO and NO2.Operating modes include port-departure,port-arrival,and cruise.Results show that variations of NO and NO2 occurred on port-arrival and port-departure modes.On cruise mode,concentration of NO was higher and stable.The average time-based emission factor of NO on cruise mode is 3.22 times and 1.74 times higher than it on port-arrival and port-departure modes,respectively.The average time-based emission factor of NO2 on port-departure mode is 1.18 times and 1.96 times higher than it on cruises and port-arrival modes,respectively.Due to the shorter distance,the average distance-based emission factors of NO and NO2 on port-arrival are higher than those on cruise and port-departure modes.The NO emission factor is higher when the engine speed is higher,while NO2 emission factor on middle engine speed is higher than it on low engine speed and high engine speed.关键词
