The effect of terebinth oil methyl ester on engine performance and exhaust emissions in a diesel engine

Menengiç yağı metil esterinin bir dizel motorunda, motor performansı ve egzoz emisyonlarına etkisinin araştırılması

Özet

Bu çalışmada menengiç yağı biyodizeli egzoz emisyonu ve motor peformansı sıkıştırma ateşlemeli birmotorda deneysel olarak incelenmiştir. Araştırmada, ilk olarak menengic yağından transesterifkasyon yöntemi ilebiyodizel elde edilmiştir. Transesterifkasyon işleminden sonra ham menengic yağı biyodizeli viskozitesi önemliölçüde azaltılmış ve Isıldeğerinin yükseldiği görülmüştür.Elde edilen biyodizel hacimsel olarak olarak %10 olaraksaf 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, dieselbiodiesel karışımlar yüksek Azot oksit (NOx) emisyonları daha düşük motor gücü,motor torku karbon monoksit(CO), hidrokarbonlar (HC) ve karbon dioksit (CO2) değerleri verdiği görülmüştür.

Abstract

In this study, exhaust emissions and performans of biodiesel from terebinth oil in a compressionignition engine was experimentally investigated. In the investigation, frstly biodiesel from menengic oil has beenobtained by transesterifcation method. The viscosity of raw menengic oil biodiesel, obtained after transesterifcation,was reduced considerably and heating value was improved. After producing biodiesel from menengic oil, itvolumetrically mixed with diesel fuel as a named B10 fuel. In the second phase of this investigation, experimenthas 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,enginemoment,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.
