“…The primary focus has been on the use of biodiesel in diesel engines [1][2][3][8][9][10][11]. The compatible physiochemical properties of biodiesel to diesel fuel have allowed up to 20% blending of biodiesel with petroleum diesel for the application in diesel engines without any modification [12][13][14][15][16][17].…”

Biodiesel is receiving increasing attention as an alternative fuel due to the ever-growing demand for energy. However, the inferior physiochemical properties of biodiesel render it incompatible for gas turbine application, which needs to meet the standard requirement of gas turbine fuel accordance to ASTM D2880. In this quest, the biodiesel-dieselbioethanol blends might be a good option. In this paper, the research work was carried out to study experimentally the performance and exhaust emission characteristics of a 25kW micro gas turbine engine (Capstone Model C30) fuelled with biodiesel-dieselbioethanol blends. The assessment on the improved fuel properties of biodiesel by blending with bio-ethanol had shown more superior atomisation characteristics performance compared to unmodified biodiesel. Moreover, the performance test in the micro gas turbine was limited up to 20% blend of biofuel, which showed improved thermal efficiency during the test. Subsequently, the emission test carried out in this work also showed significant enhancement in emissions, except nitrogen oxides (NOx) which contributed to the higher formation in comparison with the distillate diesel. Finally, B80E20 (80:20 of biodiesel-bioethanol) was proposed to be selected as an ideal blended fuel ratio to be applied in micro gas turbine engine due to its adaptability to replace diesel fuel, while showed better performance and emission properties as compared to the pure petroleum diesel.

“…Similarly, oxygenate additives were used by different researchers to improve the performance and emissions of diesel engines. Loganathan et al [18] used dimethyl ether (DME) as an additive to enhance combustion characteristics. They experimentally determined the effect of dimethyl ether (DME) with Jatropha biodiesel in a diesel engine.…”

The experimental work reported has been carried out in two parts; Jatropha biodiesel production and engine test. The engine test has been carried out on a direct injection, single-cylinder, water-cooled stationary diesel engine. Several diesel fuel blends which contain 10% and 20% by volume of JBD and 1% and 3% nitromethane were prepared. The effects of these blends on the combustion, performance, and emission characteristics of diesel engine were studied. The tests were performed under constant speed and varying load conditions without altering injection timing. A maximum increase of 11.73%, 3.2 % and 7.68 % in the brake thermal efficiency, the brake specific fuel consumption and exhaust gas temperature were achieved respectively for 20% Jatropha biodiesel and 3% nitromethane at full engine load. Compared to the pure diesel operation, the peak in-cylinder pressure of blended fuels was lower at the full load conditions. Also, the maximum net heat release rate of blended fuels was lower than that of diesel at all loading conditions. In regards to the engine emissions, the results showed that the blended fuels reduced carbon monoxide at 18.6–28.9% and unburned hydrocarbon of 7.5-24.2%, while increased the emission of nitrogen oxides at 6.9–14.3% and carbon dioxide at 4.3-10.5%.

“…al. has conducted experiment on single cylinder direct diesel engine by reduced compression ratios from 17:1 to 16.5:1 with different blends of diesel with Jatropha and analysed emission, combustion and performance characteristics, it is found that reducing compression ratios and usage of biodiesel produces almost similar amount of NOx but with lesser smoke [1].

The change in industrialisation and the increase in usage of automobile divesting the natural reserves of the fossil fuels which has driven the world towards alternative fuels especially renewable sources. One of the most prominent replaceable alternatives to the diesel is biodiesel. The research on usage of this biodiesel and modification of engines to suit these biodiesels started during the period of World War-II and the change in environmental conditions and decreasing reserves of the existing petroleum reserves formed as catalyst to accelerate this research to find better alternative biodiesel. Wide research is being done on many of the alternative biodiesels. This work mainly focuses on review of performance, emission and combustion characteristics of five most prominent biodiesels namely Jatropha, Cotton seed oil, Rubber seed oil, Mahua oil and Rapeseed oil. It is found that the brake specific fuel consumption is high for all the biodiesels because of less energy content in them in comparison with diesel. The variation of brake thermal efficiency depends on the percentage of fuel combustion and the percentage of blends used. From the review it was observed that. Even though the report of emission characteristics shows that the emissions of HC, smoke and CO by Rapeseed oil is little more comparative to that of other biodiesel blends but the performance of Rapeseed oil is superior and almost similar to that of diesel when compared with other biodiesel blends. Hence forth Rapeseed oil can be suggested as better alternative biodiesel to the diesel with certain modifications like Al 2 O 3 coatings to the piston which controls CO and HC emissions.
