Influence of Diesel Fuel and Soybean Oil Ethyl Ester Blends on the Performance and Emission Characteristics of a Diesel Engine

Abstract

In this study, blends of soybean oil ethyl ester (SOEE) and diesel fuel are tested as alternative fuel in a single cylinder, air cooled pre-combustion chamber diesel engine at different speeds and their effects on engine performance and emissions are analyzed. It is observed that the average moment obtained by 5% SOEE (B5) is 0.53% lower, the level of power obtained is 1.8% lower; however, specific fuel consumption is approximately 4.31% higher than those of diesel fuel. In the experiments conducted with 20% SOEE (B20), it is observed that the average moment is 1.74% lower, the level of power obtained is 5.91% lower; however, specific fuel consumption is approximately 10.94% higher than those of diesel fuel. Moreover, while a distinctive decrease is observed in CO emissions of fuel blends, NOx emissions are obtained very close to that of diesel fuel.

Effects on Performance, Emission and Combustion Parameters of Addition Biodiesel and Bioethanol Into Diesel Fuel

“…But, it decreased with using bioethanol due to the reason that latent evaporation heat of ethanol is higher than diesel fuel and biodiesel. Sugözü [30], Fattah et al [31], Lesnik et al [19], Mofijur et al [11], Kim and Choi [32], Lei et al [33], Dhar et al [14], Jagadish et al [34], Yılmaz et al [35], Qi et al [24] and Ong et al [28] presented that biodiesel increased NOX emission due to its higher EGT and oxygen content. Ethanol decreased by its lower EGT.…”

Biyodizel/Propanol Yakıt Karışımlarının Dizel Motor Emisyonlarına Etkisinin İncelenmesi

“…B100 yakıtı ile yaklaşık %13, P10 yakıtı ile yaklaşık %9, P20 yakıtı ile %11 oranında bir azalma olduğu elde edilmiştir. Bu güç kaybı kullanılan yakıtın alt ısıl değeri ve viskozitesi ile ilişkili olduğu önceki yapılan çalışmalarda da vurgulanmaktadır[8,16]. Laza ve Bereczky[11] yaptıkları bir çalışmada, yakıt viskozitesinin yüksek olmasının, püskürtülen yakıtın damlacık çapının büyümesine neden olduğunu ve yanma verimini olumsuz yönde etkilediğini belirtmişlerdir.…”
