Abstract (2. Language): 
Diesel engines are widely used in both land and sea transportation due to lower fuel consumption. However, the harmful nitrogene oxide (NOx) and soot emissions from diesel engines are threatening human health. A lot of research done to reduce diesel emissions. Diesel emulsion fuels that are containing specific proportions of water, can reduce harmful ezhaust emissions significantly. Therefore, emulsion fuels has been one of the important research area in recent years. In this study, effects of the diesel emulsion fuels containing % 10 (E1) and % 15 (E2) water on engine performance an exhaust emissions has been investigated. In this study, unlike the other studies 1 % auxilary emulgator mono ethylene glycol has been used as solvent to water. While the E1 emulsion has partially reducing the exhaust emissions, engine performance has significiantly reduce. With using E2 emulsion carbon monoxide (CO), NOx and soot emissions has reduced 45.9 %, 26.9 % and 18.8 % respectively. However, the motor torque decreased by 15.72 %.
Abstract (Original Language): 
Dizel motorları düşük yakıt tüketimlerinden dolayı hem kara hem de deniz taşımacılığında yaygın şekilde kullanılmaktadırlar. Ancak dizel motorlarından kaynaklanan zararlı azot oksit (NOx) ve is emisyonları insan sağlığını tehdit etmektedir. Dizel emisyonlarının azaltılabilmesi için pek çok araştırma yapılmıştır. Belirli oranlarda su içeren dizel emülsiyon yakıtları zararlı egzoz emisyonlarını önemli ölçüde azaltabilmektedirler. Bu nedenle emülsiyon yakıtlar son yıllardaki önemli araştırma alanlarından birisi olmuştur. Bu çalışmada % 10 (E1) ve % 15 (E2) su ihtiva eden dizel emülsiyon yakıtlarının motor performansı ve egzoz emisyonları üzerine etkileri incelenmiştir. Diğer çalışmalardan farklı olarak yakıtların elde edilmesinde su çözücü olarak % 1 oranında yardımcı emilgatör mono etilen glikol kullanılmıştır. E1 emülsiyonunun egzoz emisyonlarını kısmen azaltırken motor performansını da önemli ölçüde azalttığı belirlenmiştir. E2 emülsiyonunun kullanılmasıyla karbon monoksit (CO), NOx ve is emisyonlarında sırasıyla % 45,9, % 26,9 ve % 18,8 azalmıştır. Buna karşılık motor momenti % 15,72 azalmıştır.
