정속항해 시 함정 주 추진 디젤엔진의 배기가스 배출량 예측

Abstract

Abstract: This study was focused on the estimations of air pollutants, such as PM(Particulate matters), SOx(Sulfur Oxides), CO 2 (Carbon diOxides) and NOx(Nitrogen Oxides), from a diesel propulsion engine installed on a naval vessel. Legislative and regulatory actions for exhaust emissions from ships are being strengthened in international communities and national governments to protect human health and the environment. In this context, various technologies have been developed from all of the nations of the worldto meet strict standards. These regulations are based on commercial ship applications and according to size,but are not suitable for military naval vessels, which have much different engine operating conditions andhull architectures. Additionally, there is no international emission control system for military ships. Emission factors have been updated for commercial ship types from work at various research institutes; however, it is difficult to develop emission factors for military vessels because of their characteristics. In this paper, exhaust emissions from diesel engines installed on naval vessels under steady navigation condition were estimated with emission inventory methodology applied to ocean going vessels using fuel-based methods and fuel sulfur content analysis.
