바이오 디젤을 이용한 해상용 디젤엔진의 부하별 배기가스 특성 분석

Abstract

Recently, the global weather change phenomenon is appearing as abnormal climate changes all over the world. These changes in global temperature are reported by researchers as the effect of global warming. Such weather changes will occur frequently and continue to occur in countries around the world, including Korea, so national policy support is needed. In addition, international cooperation is actively needed although there are differences in policy depending on the interests of each country; and cooperation must be strengthened to avoid disaster caused by ecological destruction. Globally, low-carbon, green growth is being promoted against climate change in accordance with the carbon tax agreement. Bio fuels that can be used directly for transportation are also being researched in Korea, but it is reported that they are being used more abroad. Bio fuel is a renewable resource such as vegetable oil or animal fat, which is environmentally beneficial, decomposes safely by microorganisms, is reproducible, and has less air pollution than fossil fuels. Various studies are being attempted on the use of bio fuel because it can be applied to the existing system without modification or modification of the existing diesel engine, has fewer pollutants, and can be produced anywhere in the world. Unlike many bio diesel fuel (BDF) studies on automobile engines or on land, there are relatively few studies on bio diesel fuel for marine engines. This study uses marine gas oil (MGO), bio diesel fuel, and pure bio fuel for marine diesel engines used in ships in actual operation according to fuel type and load. The purpose is to measure the exhaust gas and air pollutants emitted during operation in real time to operate the engine efficiently and eco-friendly with the optimum engine load and fuel oil mixing ratio.
