Performance of single-cylinder compression ignition engine with indigenous castor oil bio diesel / Tek Silindirli Sıkıştırma Ateşlemeli Motorun Yöresel Hintyağı Otu Biyodizeli ile Performansı

Neat castor oil poses problems when used in CI engine. Problems are reduced to minimum by subjecting the castor oil to transesterification. Castor oil was converted to bio diesel and blended by 5%, 10%, 15% and 20% in quantity (by volume) with high-speed mineral diesel (HSD) fuel. This fuel was used on a single-cylinder compression-ignition, four-stroke diesel engine. The blended fuel gave lower emissions of CO but resulted in higher values of CO2 and NOx. Results showed that engine brake power, thermal efficiency for blended bio diesel fuel were lower than pure mineral diesel, because of lower calorific value of blended fuel. The maximum value of thermal efficiency was observed at 13% substitution of castor oil methyl ester [CME] in diesel. However, higher engine exhaust temperatures were obtained with blended fuel in comparison with that of pure mineral diesel. Chi square (X2) statistical test was applied. The value for 2 (CME) 0.0524 was observed. The value concluded that there is no effect of fuel type on fuel consumption within the given range. Overall castor oil bio diesel blends fared well in terms of engine performance. Özet: Saf hintyağı out CI (sıkıştırma ateşlemeli) motorlarda sorunlara neden olmaktadır. Sorunlar hintyağı otunun transesterifikasyona tabi tutulması ile en aza indirilmektedir. Hintyağı otu biyodizele dönüştürülmüştür ve (hacimsel olarak) %5, %10, %15 ve %20 oranlarında yüksek hızlara uygun mineral katkılı dizel yakıta (HSD) karıştırılmıştır. Bu yakıt tek silindirli sıkıştırma ateşlemeli, dört zamanlı bir dizel motorda kullanılmıştır. Karıştırılan yakıt daha düşük CO salınımları sağlamış fakat daha yüksek CO2 ve NOx salınımlarına neden olmuştur. Sonuçlar karışım yakıtın düşük kalorifik değerinden dolayı motor termal veriminin ve motor dinamometre gücünün karışım biyodizel yakıtı için saf mineral katkılı dizel yakıta göre daha düşük olduğunu göstermiştir. Termal verimin maksimum değeri %13 hintyağı otu metil esteri [CME] katkısı ile gözlemlenmiştir. Fakat saf mineral katkılı dizel yakıt ile kıyaslandığında karışım yakıtta daha yüksek motor egzoz sıcaklıkları elde edilmiştir. 2 (CME) 0.0524 gözlemlenmiştir. Chi  değerinin karesi (X2) istatistiksel testi uygulanmıştır.  değeri için verilen aralıkta yakıt tüketiminin üzerine yakıt türünün etkisi olmadığı sonucuna varılmıştır. Genel olarak hintyağı otu biyodizeli ile yapılan yakıt karışımları motor performansı açısından iyi bir performans göstermiştir.
