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.
