초록

아산화질소($N_2O$, Nitrous Oxide)는 박테리아의 물질대사와 같은 생물학적인 활동에 의하여 자연적으로 발생한다. 하지만, 최근의 대기 중 $N_2O$는 산업의 성장과 같은 인간의 활동에 의하여 증가되어져 왔다. 이 중에 대기 중의 $N_2O$농도를 증가시키는 요인들 중에 하나는 선박용 연료 연소로부터 발생하는 $N_2O$이다. 현재 해상 운송은 국제 물류의 99퍼센트 이상을 담당하고 있고, 선박척수는 물동량의 증가와 함께 증가하고 있다. 따라서, 본 연구에서는 4-행정 선박용 디젤엔진을 사용하여 다른 성분 농도들을 포함하는 연료의 연소가 $N_2O$ 배출률에 미치는 영향에 대하여 실험적인 조사를 실시하였다. 또한, 연소실 내의 연료 연소 패턴이 $N_2O$ 배출률에 미치는 영향에 대하여 평가하였다.

Nitrous oxide ($N_2O$) is naturally generated from biological activity, such as bacteria's material exchange. However, recent $N_2O$ concentration in the atmosphere has being increased by the human activities such as industrial growth. One of factors to increase $N_2O$ concentration in the atmosphere is a $N_2O$ emission caused by the combustion of marine fuel oils. The marine transportation presently handles over 99 percent of the international freight cargoes and the number of ship is continuously increasing with increment of cargoes. In this study, author conducted a series of the experimental investigations on which combustion of fuels containing different element concentrations used in a 4-stroke marine diesel engine affect $N_2O$ emissions in the exhaust gas. Moreover, it is assessed on the extent to which fuel combustion patterns in the combustion chamber affect $N_2O$ emissions.
