Dizel motorlarda alternatif yakıt olarak karpuz çekirdeği biyodizelinin değerlendirilmesi

Petrolün tükenmesi bilim adamlarını yeni enerji kaynaklarını araştırmaya itmiş ve biyodizel yenilenebilirkaynaklardan elde edilebilir olmasından dolayı en popüler alternatif yakıtlardan biri haline gelmiştir. Bu çalışmanın amacı, dizel motorlarda alternatif yakıt olarak karpuz çekirdeği yağı biyodizel (KÇB)kullanılabilirliğini değerlendirmektir. Bu çalışmada, KÇB ve KÇB20 (hacimsel olarak %80 dizel ile %20KÇB) yakıt karışımının fiziksel yakıt özelliklerine bakılmıştır. Ölçülen fiziksel yakıt değerleri, yoğunluk,setan sayısı, viskozite akma noktası ve parlama noktasıdır. Buna ek olarak, test yakıtları dizel motordaKÇB kullanımının motor performans parametreleri, azot oksitler ve karbon monoksit gibi, egzoz emisyonları üzerindeki etkilerini değerlendirmek amacıyla test edilmiştir. Motor performansı deneyleri sonuçlarına göre; KÇB kullanımıyla test motorunda tork ve fren güç değerlerinin biraz azaldığı, emisyondeğerlerinin ise KÇB kullanımı ile düzeldiği gözlemlenmiştir. Bu nedenle, karpuz çekirdeği yağı esteriçevre dostu yanma profiliyle alternatif dizel yakıt katkısı olarak tavsiye edilmektedir.

Evaluation of watermelon seed biodiesel as an alternative fuel in diesel engines

The exiguity of oil forces scientists to investigate new energy resources and biodiesel became one of themost popular alternative fuel since it can be obtained from renewable sources. The aim of this study is toevaluate availability of watermelon seed oil biodiesel (WMB) in diesel engines as alternative fuel. In thiswork, some physical fuel properties of obtained WMB and its blend with diesel fuel from %20 to %80 byvolume (WMB20) were tested. The measured fuel property values were density, cetane number, viscosity, pour point and flash point. In addition, test fuels were utilized in a diesel engine in order to evaluate effectof WMB usage on engine performance parameters and exhaust emissions such as nitrogen oxides andcarbon monoxide. According to engine performance experiments results; although both torque and brakepower values of the test engine were slightly decreased, emission values were improved with WMButilization. Therefore, the ester of water melon seed oil is advised to be a suitable alternative fuel additive to diesel fuel with its environmental friendly combustion profile.
