Abstract
Energy and air pollution have become important issues in recent years. BDF (Bio Diesel Fuel) such as esterified rapeseed oil or soybean oil, on which a lot of research was accomplished, has attracted attention as one of the new energy sources that replaces fossil fuel. Reported researches approved that in comparison with diesel oil, BDF contributes to reducing of particulate matter emission, which is harmful to the human health. Our research objective is to recycle BDF as marine fuel oil. The test was achieved as an application of BDF-mixed Diesel oil to a ship engine (the continuous rated output: 1000PS/2100rpm×2) and reducing of particulate matter emission.
