Öğe The harmful effects of diesel engine exhaust emissions(Taylor & Francis, 2012-03-16) İlkılıç, Cumali; Aydın, HüseyinWith the increase in the number of engine vehicles, air pollution is also increasing quickly; and with the increase in air pollution, all living conditions are affected in a negative way. Diesel engines also cause air pollution, which adversely affects human health and is becoming a permanent problem. A single-cylinder diesel engine was used in this work; the exhaust gas emissions, in different speed ranges, were investigated. These emissions are carbon monoxide emissions (CO), nitrogen oxides (NO x), oxygen (O 2), and carbon dioxide (CO 2). The amount of the changes in emissions was evaluated in terms of air pollution with graphics.Öğe Gaseous emission comparison of a compression-ignition engine fueled with different biodiesels(Islamic Azad University of Research and Technology, 2012-12-14) Altun, Şehmus; Öner, CengizIn this study, it was performed a comparison of the performance and emissions of two methyl ester fuels: one obtained from animal fat and the other from crude canola oil, in a compression-ignition engine against diesel fuel. The experimental results compared with diesel fuel showed that significant reductions could be obtained by biodiesel derived from animal fat in carbon monoxide and oxides of nitrogen emissions. Carbon dioxide emissions showed a trend of decreasing with the biodiesel fuels. An increase in brake specific fuel consumption was observed for different biodiesel fuels when compared with diesel fuel. It was concluded that animal tallow methyl ester performed better than canola oil methyl ester, whereas slightly higher brake torque is observed with canola oil methyl ester.
