Measurement methods and emission characteristics of nitrogen oxides

摘要

This paper introduces the results of recent activities of the Marine Air Pollution committee concerning the emissions of NO{sub}x and Nitrous Oxides, N{sub}2O, from marine diesel engines. The committee obtained the NO{sub}x emission data from more than 200 engines under operation for main engine or generator, and proposed the equations for estimating the amount of NO{sub}x emission by analyzing these data statistically. The committee also investigated the measurement methods of N20 and examined the characteristics of N{sub}2O emission from marine diesel engines by experiments and chemical kinetic calculations.
