Nitrous oxide(N₂O) concentration in the atmosphere has been constantly increased by the human activities with industrial growth after the industrial revolution. One of factors to increase N₂O concentration in the atmosphere is the N₂O emission caused by the combustion of marine fuel. Especially, a sulfur component included in marine fuel oils is known as increasing the N₂O formation in diesel combustion. Form this point of view, N₂O emission from a ship is not negligible. On the other hand, Exhaust gas recirculation(EGR) that have thermal, chemical and dilution effect is effective method for reducing the NOx emission. In this study, an author investigated N₂O reduction by using EGR on a direct injection diesel engine. The test engine was a 4-stroke diesel engine with maximum output of 12 kW at 2600rpm, and operating condition of the engine was a fixed load of 75%. The experimental oil was a blend-fuel that were adjusted with sulfur ratio of 3.5%, and EGR ratio of 0%, 10%, 20% and 30%. In conclusion, diesel fuel that contained 3.5% sulfur component increased SO₂ emission in exhaust gas, and increment of EGR ratio reduced NO emission. Moreover, N₂O emission was decreased as over 50% at EGR ratio of 10% and reduced 100% at EGR ratio of 30% compared with N₂O emission of 0% EGR ratio.
