The Effect of Pistacia Therebinthus L. Oil Biodiesel Blend on Emissions of a CI Engine

Abstract

In this study, combustion and exhaust emissions of a diesel engine operating with diesel fuel and diesel–biodiesel blends have been investigated. In this study, firstly biodiesel has been obtained from terebinth oil by transesterification method. The viscosity of raw terebinth oil obtained biodiesel was reduced considerably after transesterification. After producing biodiesel from terebinth oil, it was volumetrically mixed with diesel fuel volumetrically 50% and named as B50 fuel. In the secondly, in this study, experiment has been conducted with diesel fuel and B50 fuel in a compression ignition (CI) engine. Compared with conventional diesel fuel, B50 fuel showed lower carbon monoxide (CO), hydrocarbon (HC) and carbon dioxides (CO2), but higher oxides of nitrogen (NOx) emissions.

Key words: alternative fuels, terebinth oil, biodiesel, diesel fuel, emission.
