Abstract
This paper introduces the results of recent activities of the Marine Air Pollution committee concerning the emissions of NOx and Nitrous Oxides, N2O, from marine diesel engines. The committee obtained the NOx emission data from more than 200 engines under operation for main engine or generator, and proposed the equations for estimating the amount of NOx emission by analyzing these data statistically. The committee also investigated the measurement methods of N2O and examined the characteristics of N2O emission from marine diesel engines by experiments and chemical kinetic calculations.
