“…Biodiesel has superior lubricity (which reduces engine wear) over petroleum diesel fuel (Knothe, 2005d). Lubricity results of biodiesel and petroleum diesel using industry test methods indicate that there is a marked improvement in lubricity when biodiesel is added to conventional diesel fuel (Anastopoulos et al, 2001). Research conducted using 1-2 percent blends of biodiesel mixed with petroleum diesel fuel revealed an increase in lubricity.…”

ABSTRACT:Biodiesel is a renewable, biodegradable, environmentally benign, energy efficient, substitution fuel which can fulfill energy security needs without sacrificing engine's operational performance. Thus it provides a feasible solution to the twin crises of fossil fuel depletion and environmental degradation. The properties of the various individual fatty esters that comprise biodiesel determine the overall properties of the biodiesel fuel. In turn, the properties of the various fatty esters are determined by the structural features of the fatty acid and the alcohol moieties that comprise a fatty ester. Better understanding of the structure-physical property relationships in fatty acid esters is of particular importance when choosing vegetable oils that will give the desired biodiesel quality. By having accurate knowledge of the influence of the molecular structure on the properties determined, the composition of the oils and the alcohol used can both be selected to give the optimal performance. In this paper the relationship between the chemical structure and physical properties of vegetable oil esters is reviewed and engineering fatty acid profiles to optimize biodiesel fuel characteristics is highlighted.

“…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.…”

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.

Diesel fuel refers to the fuel that is used in compression-ignition engines (diesel engines). It is generally material boiling in the C 11 -C 22 hydrocarbon range. The requirements for diesel fuel are often diametrically opposed to that of motor-gasoline (Chapter 13). In motor-gasoline, it is important to suppress autoignition of the fuel to allow spark ignition to be correctly timed for good engine performance. In diesel fuel, it is important that the fuel autoignites and that the delay between fuel injection and the start of combustion is short.Compression-ignition engines operate at high compression ratios, typically around 15-17 : 1. This improves the thermodynamic efficiency of the engine, and on average compression-ignition engines are more efficient than spark-ignition engines. The engine itself is heavier, and traditionally it has been applied mainly for heavier vehicles. This situation has changed and, despite the higher cost of compression-ignition engines as compared to spark-ignition engines, there has been a marked shift in preference for diesel-powered passenger vehicles in Europe. This change is partly due to an increase in environmental awareness. Better engine efficiency leads to lower fuel consumption and can be translated into less CO 2 emitted per distance traveled. The move to vehicles with lower rated emissions (in grams of CO 2 per kilometer) is supported by the policies of the European Union.This shift in transportation fuel preference for the passenger vehicle market had a marked impact on refineries. The hydrogen in a typical conventional crude oil refinery is obtained from catalytic naphtha reforming. As the demand for motor-gasoline decreases, the need for reformate also decreases, which in turn reduces hydrogen production. Yet, refining crude oil to diesel fuel requires more hydrogen than refining crude oil to motor-gasoline. In each refinery there is a minimum motor-gasoline to diesel fuel ratio beyond which refining becomes inefficient and costly. The shift toward diesel fuel has created an imbalance in refinery production and in practice this imbalance in Europe is corrected by exporting motor-gasoline and importing diesel fuel. In the long run, it will be interesting to see how this might affect diesel fuel specifications, which over time have made diesel fuel production more difficult.Diesel fuel, like motor-gasoline, is a major consumer product and exerts a tremendous influence on the economy and the environment. Diesel fuel specifications are consequently subject to technical, environmental, and political pressures (Section 13.1).Fischer-Tropsch Refining, First Edition. Arno de Klerk.
