“…The optimized conditions for Moringa biodiesel production were reached after preliminary experiments based on the literature [30,31]. The obtained M. oleifera presented 81.6% of oleic fatty ester (as methyl ester) as the major constituent, which is in agreement with a previous study by Mofijur et al for a Moringa methyl ester that presented 74.1% of oleic fatty ester [32]. The physical-chemical properties of biodiesels met the minimum and maximum limits of the EN 14214.…”

h i g h l i g h t sHigh induction period (IP) of 19.3 h for Moringa oleifera methyl ester. High antioxidant activity of the extract verified by DPPH method and voltammetry. Ethanolic extracts of M. oleifera leaves proposed as additives for biodiesel. The 98% (v/v) extract increased IP value of soybean biodiesel from 3.8 to 10.3 h. Efficiency of the extract was higher than TBHQ at the same concentration. a b s t r a c tThis work reports the use of Moringa oleifera oil and leaves as potential sources for the production of biodiesel and antioxidant additives for biodiesels, respectively. The M. oleifera methyl ester was prepared by a two-step reaction and exhibited physical-chemical properties that met the minimum or maximum limits of the EN 14214, emphasizing the high induction period (IP) of 19.3 h. Ethanolic extracts of M. oleifera leaves were evaluated as additives to increase the IP value of biodiesels. The results indicate that the 98% (v/v) ethanolic extract increased IP values of soybean biodiesel from 3.8 to 10.3 h using the 100 lg g À1 of extract, showing better performance than the synthetic antioxidant tert-butyl-hydroquinone. The extract also provided similar efficiency to methyl esters produced from sunflower, colza, corn and residual cooking oils. These results evidence the promising use of M. oleifera not only for biodiesel production but also as a source of antioxidant additives for biodiesels with low oxidation stability.

The study investigated the engine performance and emission using biodiesel from soybean oil and waste cooking oil. The fuel properties of these biodiesels were determined using ASTM D6751and EN 14214 standards. The fuels were tested in a multi-cylinder diesel engine with an electromagnetic dynamometer and a 5-gas analyser was used for emission analysis. The result shows that the thermal performance of the engine slightly decreases with increase of the biodiesel blends ratio (i.e. B5, B10, B15, B20 and B50). On the other hand, emission decreases with the increase of biodiesel blends. The reduction in emissions was different for both biodiesels. Waste oil biodiesel showed better trends of emissions reduction with increase of the biodiesel percentage compared with soybean biodiesel. The brake specific fuel consumption (BSFC) of both biodiesels is (6.05%, 9.13%, 12.36% and 18.57% for soybean) and (8.17%, 11.40%, 17.71% and 14.96% for waste cooking oil) higher than diesel, respectively. However, soybean biodiesel consumed less fuel and produced more power and torque compared to waste oil biodiesel. The study concluded that B10 soybean biodiesel blend produced more consistent and expected results than waste oil biodiesel from the performance and emission point of view.

“…It is very urgent to find out alternative fuels for transportation sector as this sector is emitting higher GHG emission and contribute to the rapid growth of global oil demand. Recently, attention has been drawn to develop cleaner alternative fuels from renewable sources to reduce the harmful emission to the air and to reduce the dependency on the petro-diesel fuel [5]. The most feasible alternative for vehicles being considered globally are biofuel such as biodiesel and ethanol due to their renewable property and reduction of fossil CO 2 discharge which most probably contributes to the global climate changes.…”

Vehicles are the main sources for environmental pollution especially those associated with diesel engines. It causes a number of health diseases and harm to the ecosystem. It is very urgent to find alternative fuel for vehicles. Biofuel is an alternative for vehicles which have potential to reduce engine emissions and maintain the air quality better. In recent years, worldwide biofuel production and use raised drastically. Some developed countries have put their target and mandate to use biofuel. The aim of this review is to discuss the impact of biofuel on diesel engines emission. From this review it is found that biofuel significantly reduces engine emissions and it has potential to reduce more than 80% of GHG emission. Finally, biofuel can be a viable alternative to be used as a transportation fuel.
