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

Öz

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. Keywords: Alternative fuels; Menengic oil; Biodiesel; Diesel fuel; Emissionn CI engines.

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

Öz

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. (B10 ).Araştırmanın ikinci aşamasında Dizel yakıtı ve Dizel Biyodizel karışımı (B10) dört zamanlı sıkıştırmalı enjeksiyon motorunda denendi. Geleneksel dizel yakıt ile karşılaştırıldığında, diesel– biodiesel karışımlar yüksek Azot oksit (NOx) emisyonları daha düşük motor gücü,motor torku karbon monoksit (CO), hidrokarbonlar (HC) ve karbon dioksit (CO2) değerleri verdiği görülmüştür.
