Bu çalışmada atık yağlardan elde edilen biyodizelin bir dizel motorda alternatif yakıt olarak kullanılmasının motor performansı ve emisyonlarına etkisi deneysel olarak araştırılmıştır. Deneylerde dört zamanlı, tek silindirli, direkt püskürtmeli bir motor kullanılmıştır. Test motoru, dizel ve saf biyodizel yakıtları ile sabit bir hızda ve farklı yüklerde test edilmiştir. Test sonuçlarına göre, biyodizel kullanımı ile dizel yakıta göre fren özgül yakıt tüketiminde %3 artış, fren özgül enerji tüketiminde %5 azalma elde edilmiştir. Ayrıca, NOx, CO ve is emisyonlarında dizel yakıtına göre sırasıyla %17, %33 ve %31 oranlarında azalma, HC emisyonunda ise %24 oranında artış tespit edilmiştir.
In this study, effect of biodiesel, as an alternative fuel, which was produced from waste oil on motor performance and emissions was investigated experimentally. In the experiments, diesel engine which had four strokes, single cylinder and direct injection was used. Diesel and pure biodiesel were used in engine as a fuel. Besides, the test engine was tested at constant speed under various loads. According to experimental results, when the biodiesel was used as a fuel, brake specific fuel consumption was increased about 3% and break specific energy consumption was decreased about 5% as well. Besides, NOx, CO, and smut emissions were decreased about 17%, 33%, and 31%, respectively. Moreover, HC emission was increased about 24%.
