Pamuk Yağı Biyodizelinin Motor Ses Seviyesine Olan Etkilerinin İncelenmesi

Dizel motorlar, sağladıkları yakıt ekonomisi ve yüksek termal verimleriyle günümüzde en çok tercih edilen motor tipidir. Ancak sıkıştırma ateşlemeli motorlarda yüksek sıkıştırma oranından dolayı meydana gelen ses dizel motorların en önemli dezavantajlarındandır. Yakıtın yanması sırasında meydana gelen ses hem yolcuların hem de sürücünün yolculuk konforunu azalmasına yol açmaktadır. Biyodizel, bitkisel ve hayvansal yağlardan elde edilebilen dizel yakıta alternatif yenilenebilir enerji kaynağıdır ve mevcut dizel motorlarda değişiklik yapmadan kullanılabilir.Bu çalışmada, pamuk yağı esterinin dizel motorlarda kullanımının motorlarda ses seviyesine olan etkileri deneysel olarak incelenmiştir. Yakıt olarak PB20 ve PB100 kullanıldığında test motoru tarafından üretilen ses seviyelerinin dB(A), dB(C) ve dB(Z) cinsinden dizel yakıtla karşılaştırıldığında azaldığı gözlemlenmiştir.

Investigation of Effects of Cotton Oil Biodiesel on Engine Noise Level

Diesel engines are the most preferred engine type today with their fuel economy and high thermal efficiency. However, the noise coming from compression ignition engines due to the high compression ratio, is a major disadvantage of diesel engines. The noise created during combustion of the fuel leads to a decrease in the riding comfort of both the passenger and the driver. Biodiesel is an alternative renewable energy source for diesel fuel that can be obtained from vegetable and animal oils and can be used without modification in existing diesel engines.In this study, the effect of the use of cottonseed ester on diesel engines in engines was investigated experimentally. It has been observed that when using PB20 and PB100 as fuel, the sound levels produced by the test motor are reduced when compared to diesel in dB (A), dB (C) and dB (Z).
