Abstract (2. Language): 
In this study, the effects of diethyl ether (DEE)−diesel fuel blends on the performance of a diesel engine investigated experimentally. The blends were prepared with the addition of 2.5, 5, 7.5, and 10 vol. % of DEE with a specified amount of diesel fuel. In the experiments, a single cylinder direct injection (DI) diesel experimental engine was used and compression ratio was fixed at 20. The experiments were performed with neat diesel fuel and DEE−diesel fuel blends at various engine speeds and wide open throttle conditions. The results of the study show that DEE addition to diesel fuel causes to decrease in engine performance parameters, i.e., brake mean effective pressure, brake torque and brake power. The decrement in performance parameters increased with increasing blending ratio. The maximum decrement in brake mean effective pressure was obtained with DEE10 blend as about 5.1%. However, brake thermal efficiency increases and brake specific fuel consumption decreases up to 7.5% DEE blending ratio. The maximum increment in brake thermal efficiency was obtained with DEE7.5 blend as about 10.9%. The same fuel blend gives about 8.7% reduction in brake specific fuel consumption. Additionally, exhaust gas temperature decreases and air excess coefficient increases with increasing DEE blending ratio.

Abstract (Original Language): 
Bu çalışmada, dietil eter (DEE)−motorin karışımlarının motor performansına etkileri deneysel olarak incelenmiştir. Yakıt karışımları motorin içerisine hacimsel olarak %2,5, %5, %7,5 ve %10 oranlarında dietil eter karıştırılarak hazırlanmıştır. Deneylerde direk enjeksiyonlu tek silindirli bir dizel deney motoru kullanılmış ve sıkıştırma oranı 20 seçilmiştir. Deneyler saf motorin ve dietil eter−motorin yakıt karışımları kullanılarak tam gaz durumunda ve farklı devir sayılarında yapılmıştır. Çalışma sonuçları motorine dietil eter katılmasının ortalama efektif basınç, döndürme momenti ve efektif güç gibi motor performans parametrelerinde düşüşe neden olduğunu göstermiştir. Performans parametrelerindeki düşüş artan karışım oranı ile artmıştır. Ortalama efektif basınçtaki maksimum düşüş %5,1 olarak DEE10 karışımı ile elde edilmiştir. Diğer taraftan, %7,5 karışım oranına kadar efektif verim artmış ve özgül yakıt tüketimi azalmıştır. Efektif verimde en yüksek artış %10,9 olarak DEE7,5 karışımı ile elde edilmiştir. Aynı yakıt karışımı özgül yakıt tüketiminde %8,7 düşüş sağlanmıştır. Ayrıca artan dietil eter oranı ile hava fazlalık katsayısında artış ve egzoz gazı sıcaklığında azalma meydana gelmiştir.
