Nitrous Oxide Emissions from Marine Diesel Engine Sources

The aim of this paper is to study the effect of ship operation on formation of N2O emissions and the influence of temperature changing in the exhaust pipe diesel engine. The data were taken from training ship Fukae Maru during the voyage project in September 2004 and the diesel engine experiment in the laboratory. Data from the Fukae Maru training ship were carried out at different operating conditions. Two sampling points, in the engine room and funnel were set up in the experiment. The N2O analyzer model 46C was used to measure exhaust emissions. A direct-injection diesel engine with naturally aspirated (model NF-19SK YANMAR) single cylinder was employed to test the emission and engine performance. The experiment data shows that in the 15 degree PPA, the nitrous oxide emissions higher than others condition.
