| Research Abstract |
In this experimental study, the authors investigated N2O emission characteristics of an actual ship at the sea, and examined relationships between N2O and other gaseous emissions. The experimental results showed that N2O emission exhibited different characteristics compared with NO which makes up over 80 percent in NOX, and had exhaust characteristic very similar to SO2 emission. But when based on the excess air ratio, the difference between these two species increased with decreasing excess air ratio.
