The comparison of engine performance and exhaust emission characteristics of sesame oil-Diesel Fuel mixture with Diesel Fuel in a direct injection Diesel engine.
Renewable Energy, 2008Co-Authors: Şehmus Altun, Hüsamettin Bulut, Cengiz ÖnerAbstract:The use of vegetable oils as a Fuel in Diesel engines causes some problems due to their high viscosity compared with conventional Diesel Fuel. Various techniques and methods are used to solve the problems resulting from high viscosity. One of these techniques is Fuel blending. In this study, a blend of 50% sesame oil and 50% Diesel Fuel was used as an alternative Fuel in a direct injection Diesel engine. Engine performance and exhaust emissions were investigated and compared with the ordinary Diesel Fuel in a Diesel engine. The experimental results show that the engine power and torque of the mixture of sesame oil–Diesel Fuel are close to the values obtained from Diesel Fuel and the amounts of exhaust emissions are lower than those of Diesel Fuel. Hence, it is seen that blend of sesame oil and Diesel Fuel can be used as an alternative Fuel successfully in a Diesel engine without any modification and also it is an environmental friendly Fuel in terms of emission parameters.

Can Fischer−Tropsch Syncrude Be Refined to On-Specification Diesel Fuel?
Energy & Fuels, 2009Co-Authors: Arno De KlerkAbstract:The interchangeable colloquial use of the terms “distillate” (boiling range) and “Diesel Fuel” (distillate meeting legislated Fuel specifications), led to misleading perceptions about the suitability of Fischer−Tropsch syncrude for Diesel Fuel production. Two questions are addressed: Can Fischer−Tropsch syncrude be refined to Diesel Fuel, and which Fischer−Tropsch technology is best for maximizing distillate and ultimately Diesel Fuel production? The distillate yield that can be obtained from Fischer−Tropsch syncrude in an uncomplicated refinery employing only hydrocracking and/or oligomerization follows the order: Fe-LTFT > Co-LTFT > Fe-HTFT. Conversely, producing Diesel Fuel (not distillate) from Fe-HTFT syncrude is easier. On a molecular level, Fischer−Tropsch syncrude was found to be unsuitable for the production of EN 590:2004 Diesel Fuel in high yield. There is a trade-off between distillate density, cetane number, and yield, which is called the Fischer−Tropsch density−cetane−yield triangle. It is p...

There is a trade-off between distillate density, cetane number, and yield, which is called the Fischer−Tropsch density−cetane−yield triangle. It is possible to meet any two of these three requirements without too much refining effort, but meeting all three with Fischer−Tropsch syncrude as feed material, is difficult. Strategies have been suggested to overcome the Fischer−Tropsch density−cetane−yield triangle and to improve the yield of on-specification Diesel Fuel. Some industrial implications for the standalone Fischer−Tropsch-based production of Diesel Fuel are discussed. High-temperature Fischer−Tropsch (HTFT) and low-temperature Fischer−Tropsch (LTFT) Fuels refinery designs based on current refining technology to maximize EN 590:2004 Diesel Fuel are provided

Metal oxide gas sensor array for the detection of Diesel Fuel in engine oil
Sensors and Actuators B-chemical, 2008Co-Authors: Simonetta Capone, Marzia Zuppa, Dominique S. Presicce, Luca Francioso, Flavio Casino, Pietro SicilianoAbstract:Abstract We developed a novel method to detect the presence of unburned Diesel Fuel in lubricating oil for internal combustion engine. The method is based on the use of an array of different gas microsensors based on metal oxide thin films deposited by sol–gel technique on Si substrates. The sensor array, exposed to the volatile chemical species of different Diesel Fuel engine oil samples contaminated in different percentages by Diesel Fuel, resulted to be appreciably sensitive to them. Principal component analysis (PCA) and self-organizing map (SOM) applied to the sensor response data set gave a first proof of the sensor array ability to discriminate among the different Diesel Fuel diluted lubricating oils. Moreover, in order to get information about the headspace composition of the Diesel Fuel-contaminated engine oils used for gas-sensing tests, we analysed the engine oil samples by static headspace solid phase micro-extraction/gas chromatograph/mass spectrometer (SHS-SPME/GC/MS).

Development of a soft sensor for Diesel Fuel quality estimation
Chemical Engineering and Technology, 2010Co-Authors: Nenad Bolf, Goran Galinec, Tomáš BakšaAbstract:A soft sensor was developed for quality estimation of Diesel Fuel as the crude distillation unit product. Due to the stringent Fuel quality standards and the growing need to produce various gradations of quality with different feeds, laboratory testing and quality control of the products have become a necessity. On the basis of available continuous temperature measurements and flows of appropriate process streams, software sensors for estimating the cold filter plugging point of Diesel Fuel were developed. Nonlinear software sensor models were built with the best results achieved by using multilayer neural networks. Statistical data analysis was carried out and the data were critically evaluated. The results showed that soft sensors can be applied for refinery product quality estimation of Diesel Fuel as an alternative to laboratory testing. So, it becomes possible to continuously estimate Fuel quality and to apply methods of inferential control for plant operation optimization. © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
