    Comparison of some fuel properties of biodiesels produced from vegetable oils
    (SILA SCIENCE, 2012) Eryilmaz, Tanzer; Bacak, Seda; Ozrahat, Evrim
    In recent years, interest of the studies on biodiesel production is increasing rapidly as the biodiesel is an eco-friendly product and also a good alternative to the gasoline due to the rapid increases in gasoline prices and as the gasoline will run out soon. Also, as the oil reserves are in certain areas and the countries not having these reserves wanting to reduce dependence on foreign countries for energy, revealed the inevitability of alternative energy sources. Biodiesel vegetable oils can be produced from waste vegetable oils, animal fats and algaes. Vegetable oils evaluated on the basis of countries can vary in type and amount according to the climate change and soil type. In this study, the density, kinematic viscosity, flash point, water content, copper strip corrosion, CFPP, cloud point, pour point and heating value fuel properties of biodiesels produced by transesterification method from eight kinds of oils such as peanut oil, sunflower oil, olive oil, grape seed oil, canola oil, safflower oil, soy bean oil, cottonseed oil are determined, compared to each other and their compliance to the standard IS EN 14214 is investigated.

    Investigation of the characteristics of biodiesel from Balci species of safflower
    (2012) Öğüt, Hüseyin; Oğuz, Hidayet; Bacak, Seda; Mengeş, O. Hakan; Köse, Arzu; Eryılmaz, Tanzer
    Safflower whose genetic origin is Anatolia was forgotten in time; however, it started to attract attention again as a raw material supply when biodiesel was started to be used in Turkey. Thus, its production has increased. The species like Yenice, Dinçer Remzibey 05 were cultivated. In addition to these three species, Balcı safflower species was cultivated and introduced to public. In this study, Balcı safflower which is a new species was obtained from Anatolian Agricultural Research Institute and oil was extracted from this safflower and biodiesel was produced from this oil. Oil acid components and some fuel characteristics of the biodiesel produced were examined.

    Investigation of the Performance and Emission Values of Non-Standard Fuels at Diesel Engines
    (2010) Eryılmaz, Tanzer; Öğüt, Hüseyin; Oğuz, Hidayet; Bacak, Seda
    Diesel engines have very important role at transportation and agriculture. Due to the fuels used in diesel engines being expensive and tendency of increase in its price, consumers have been forced to seek alternative fuels. However, the effects of fuels on environment and engines have been ignored. In this study, together with diesel fuel oil as a reference, the effects of number 10 mineral oil and waste vegetable neutralized oil on engine performance and exhaust emission were investigated. The engine used in study was diesel with single cylinder, four cycle, direct injection, and rate power of 15 HP engine. Results of the study showed that when both waste vegetable oil and number 10 mineral oil were used, the power and moment values have decreased 9.1% and 2.8%, respectively while the specific fuel consumption has increased.
