摘要: Air pollution caused by ship exhaust emission is receiving more and attention. The physical chemical properties of fuels, such as sulfur content PAHs content, potentially had a significant influence on air pollutant emissions from inland vessels. In order to investigate the effects fuel qualities atmospheric systematically, series experiments was conducted based method actual testing. As result, SO2, PM NOx rates all increased with increase main engine rotating speed under cruise mode, while factors were inversely proportional speed. Moreover, SO2 factor changed little summary, fuel-dependent specific direct reflection in fuel. However, impacted vessels because formation mechanisms conditions. Implications: Ship activity considered be third largest source China. particular, pollutants emitted ships river ports waterways have impact regional quality pose threat health local residents owing high concentration poor diffusion. study relationship between can provide foundational data for authority formulate reasonable appropriate policies reducing due
