Application of Taguchi's methods to investigate factors affecting emissions of a diesel engine running with tobacco oil seed methyl ester

Parlak, Adnan; Karabaş, Hülya; Özsert, İbrahim; Ayhan, Vezir; Cesur, İdris (INDERSCIENCE ENTERPRISES LTD, 2012)

Different kinds of vegetable oils and their methyl/ethyl esters have been tested in diesel engines. However, studies reporting the effects of tobacco seed oil and Tobacco Seed Oil Methyl Ester (TSOME) on emissions of diesel ...
Bir dizel motoruna buhar enjeksiyonunun NOx ve is emisyonlarına etkisinin araştırılması

Ayhan, Vezir (Sakarya Üniversitesi, 2009)

NOX emisyonlarının oluşma nedeni yüksek sıcaklıklardır ve özellikle yanma odası sıcaklığının 1800 oC' yi geçtiği anda NOX oluşum hızı artmaktadır. Dolayısıyla NOX emisyonunu azaltmanın ana mekanizması yanma odası sıcaklığının ...
Comparison of the Variables Affecting the Yield of Tobacco Seed Oil Methyl Ester for KOH and NaOH Catalysts

Parlak, Adnan; Karabaş, Hülya; Ayhan, Vezir; Yaşar, Halit; Soyhan, Hakan Serhad; Özsert, İbrahim (AMER CHEMICAL SOC, 2009)

Reaction temperature, alcohol/oil molar ratio, type and amount of catalyst, reaction duration, and the water content in free fatty acid are the most important parameters in biodiesel production by the transesterification ...

Effects of tobacco seed oil methyl ester on performance and exhaust emissions of diesel engine

Parlak, Adnan; Karabaş, Hülya; Özsert, İbrahim; Ayhan, Vezir; Cesur, İdris (ELSEVIER SCI LTD, 2013)

Tobacco seed oil (TSO) was considered as a potential alternative fuel for compression ignition engines as the tobacco plant has high ecological tolerance and its farming can be realised on five different climatic regions ...
Metanol- benzin karışımlarının MgO-ZrO2 termal bariyer çemberli bir motorda performans ve emisyonlara etkisi

Ayhan, Vezir (Sakarya Üniversitesi, 2006)

Hidrokarbon esaslı yakıtların kullanıldığı taşıt sayısının her geçen gün artması dünyayıönemli çevre sorunlarıyla karşı karşıya bırakmaktadır. Diğer taraftan enerji kullanımıarttıkça, sınırlı olan enerji kaynakları kendilerini ...
Thermal analysis of a partially ceramic coated piston: Effect on cold start HC emission in a spark ignition engine

Cerit, Muhammet; Ayhan, Vezir; Parlak, Adnan; Yaşar, Halit (PERGAMON-ELSEVIER SCIENCE LTD, 2011)

Effect of partially thermal barrier coating on piston temperature distribution and cold start HC emissions of a spark ignition (SI) engine are investigated numerically and experimentally. A Thermal analysis was performed ...
