Ship’s fuel oil with a high viscosity and high impurities is likely to cause incomplete combustion of diesel engine, and is therefore highly likely to cause emission of air pollutants such as PM (Particulate matter), NOx (Nitrogen oxides), SOx (Sulfur oxide) from the ship.
Recently, restrictions on the emission of air pollutants are being more tightened on the ship. So it is required to develop more effective national policies on the reduction of air pollutants emission from the ship.
In order to do so, it is necessary to analyze the factors that affect the emission of air pollutants from diesel engines for the ship and use its results to establish policies for reducing emissions.
This study investigated that the increase in sulfur content of MGO (Marine Gas Oil) used as ship’s fuel oil has some effect on kinetic viscosity rise, SFC (Specific Fuel oil Consumption) improvements and the increase in SOx (Sulfur Oxide) emissions on high speed marine diesel engine under MCR 500 ㎾. SFC (Specific Fuel oil Consumption) improvements is due to the kinetic viscosity increase of fuel oil which affects the reduction of friction loss in attached fuel oil supply pump, etc. And this study also found that increased sulfur content in fuel oil does not affect the emissions of NOx(Nitrogen Oxide), THC (Total Hydrocarbon Content) and CO (Carbon monoxide), but an increase above a certain level of sulfur content affects the increase in PM (Particulate matter) emissions.
