“…Oxygen containing compounds such as fatty acids and their derivatives are superior friction reducing agents [12][13][14][15][16][17][18][19][20][21][22][23][24]. These compounds adsorb or react on rubbing surfaces to reduce adhesion between contacting asperities and limit friction, wear and seizure.…”

Effect of dicarboxylic acid esters on the lubricity of aviation kerosene for use in CI engines

To reduce their fuel related logistic burden, North Atlantic Treaty Organization (NATO) Armed Forces are advancing the use of a single fuel for both aircraft and ground equipment. To this end, F-34 (the commercial equivalent is Jet A-1) is replacing distillate diesel fuel in many applications. However, tests conducted with this kerosene type on high frequency reciprocating rig showed that this type of fuel causes unacceptable wear. This excessive wear is caused by the poor lubricity of aviation fuel. In order to make this type of fuel compatible with direct injection compression engines, seven di-carboxylic acid esters have tested to improve the lubricity of kerosene. Tribological results showed that all esters tested in this series of experiments seem to be suitable for increasing the kerosene lubricity to a satisfactory level.

“…The development of biodiesels is being driven by the need for reducing emissions from diesel engines without modifying engines and for saving energy. Biodiesels used as alternative fuels in diesel engines reduce the emissions of hydrocarbons (HC), carbon monoxide (CO), sulfur oxide (SO 2 ), and PAHs (Antolin et al, 2002;Beer et al, 2002;Cardone et al, 2002;Durbin et al, 2002;Dorado et al, 2003;Kalam et al, 2003;Kalligeros et al, 2003;Goodrum and Geller, 2005;Hu et al, 2005;Legreid et al, 2007;Yuan et al, 2007;Chien et al, 2009;Pehan et al, 2009;Yuan et al, 2009;Tsai et al, 2010;. Previous studies and measurements of NO x emissions from biodiesel showed an increase in NO x emissions (Scholl and Sorenson, 1993;Graboski et al, 1996;Choi et al, 1997;Graboski and McCormick, 1998;Yoshimoto et al, 1999;McCormick et al, 2001;Grimaldi et al, 2002;Tat and Van Gerpen, 2003;Tat, 2004;Saravanan et al, 2010;Sun et al, 2010).…”

The development of biodiesels is being driven by the need for reducing emissions from diesel engines without modifying engines and for saving energy. The major obstacle to biodiesel commercialization is the high cost of raw materials. Biodiesel from waste cooking oil is an economical source and an effective strategy for reducing the raw material cost. Although biodiesels made from waste cooking oil have been previously investigated, PAH emissions from heavy-duty diesel engines (HDDEs) with catalyzer fueled with biodiesel from waste cooking oil and its blend with ultra-low sulfur diesel (ULSD) for the US-HDD transient cycle have seldom been addressed. Experimental results indicate that ULSD/WCOB (biodiesel made from waste cooking oil) blends had lower PM, HC, and CO emissions but higher CO 2 and NO x emissions when compared with that of ULSD. Using ULSD/WCOB blends instead of ULSD decreased PAHs by 14.1%-53.3%, PM by 6.80%-15.1%, HC by 6.76%-23.5%, and CO by 0.962%-8.65% but increase CO 2 by 0.318-1.43% and NO x by 0.384-1.15%. Using WCOB is an economical source and an effective strategy for reducing cost, and solves the problem of waste oil disposal.

“…Therefore, the issue of lubricity in fuel is becoming increasingly important with respect to diesel engine operation. Biodiesels typically have superior lubrication properties when compared with petroleum diesel [120]. Studies show that biodiesel derived from vegetable oils can significantly increase diesel fuel lubricity at blend concentrations of less than 1%.…”

“…This study also reported that pure free fatty acids, monoacylglycerols, and glycerol possess better lubricity than pure esters. The main components responsible for biodiesel lubricity are FAMEs, hydroxyl groups and monoacylglycerols followed by free fatty acids (FFAs) and diacylglycerols, whereas triglycerols do not have any significant effect on the lubricity of biodiesel [93,120] On the other hand, the structures of fatty acids have an impact on biodiesel lubricity. Increasing saturation leads to a stronger lubrication layer as molecules can align themselves more easily in straight chains and when they are packed closely on the surface [123].…”

The Use of Artificial Neural Networks for Identifying Sustainable Biodiesel Feedstocks

Abstract:Over the past few decades, biodiesel produced from oilseed crops and animal fat is receiving much attention as a renewable and sustainable alternative for automobile engine fuels, and particularly petroleum diesel. However, current biodiesel production is heavily dependent on edible oil feedstocks which are unlikely to be sustainable in the longer term due to the rising food prices and the concerns about automobile engine durability. Therefore, there is an urgent need for researchers to identify and develop sustainable biodiesel feedstocks which overcome the disadvantages of current ones. On the other hand, artificial neural network (ANN) modeling has been successfully used in recent years to gain new knowledge in various disciplines. The main goal of this article is to review recent literatures and assess the state of the art on the use of ANN as a modeling tool for future generation biodiesel feedstocks. Biodiesel feedstocks, production processes, chemical compositions, standards, physio-chemical properties and in-use performance are discussed. Limitations of current biodiesel feedstocks over future generation biodiesel feedstock have been identified. The application of ANN in modeling key biodiesel quality parameters and combustion performance in automobile engines is also discussed. This review has determined that ANN modeling has a high potential to contribute to the development of renewable energy systems by accelerating biodiesel research.
