Menengiç yağı Metil Esterinin Bir Dizel Motorunda, Motor Performansı ve Egzoz Emisyonlarına Etkisinin Araştırılması

Bu çalışmada menengiç yağı biyodizeli egzoz emisyonu ve motor peformansı sıkıştırma ateşlemeli bir motorda deneysel olarak incelenmiştir. Araştırmada, ilk olarak menengic yağından transesteri kasyon yöntemi ile biyodizel elde edilmiştir. Transesteri kasyon işleminden sonra ham menengic yağı biyodizeli viskozitesi önemli ölçüde azaltılmış ve Isıldeğerinin yükseldiği görülmüştür.Elde edilen biyodizel hacimsel olarak olarak %10 olarak saf dizel yakıtı ile karıştırıldı.

The Effect of Terebinth oil Methyl Ester on Engine Performance and Exhaust Emissions in a Diesel Engine

In this study, exhaust emissions and performans of biodiesel from terebinth oil in a compression ignition engine was experimentally investigated. In the investigation, rstly biodiesel from menengic oil has been obtained by transesteri cation method. The viscosity of raw menengic oil biodiesel, obtained after transesteri cation, was reduced considerably and heating value was improved. After producing biodiesel from menengic oil, it volumetrically mixed with diesel fuel as a named B10 fuel. In the second phase of this investigation, experiment has been conducted with neat diesel fuel and biodiesel blend (B10 fuel) in a four stroke compression injection (CI) diesel engine. Compared with conventional diesel fuel, diesel–biodiesel blends showed lower engine power,engine moment,carbon monoxide (CO), hydrocarbon (HC) and carbon dioxides (CO2) but higher oxides of nitrogen (NOx) emissions.
