Palm oil methyl ester (POME) produced from crude palm oil have some excellent properties which makes it a feasible alternative to diesel fuel. However, its higher oxygen content makes it nitrogen oxide emission prone when burned in diesel engines. This problem can be resolved by emulsifying POME with distilled water in the presence of suitable surfactant. Two phase water in oil emulsion is prepared by using ultrasonic bath sonication. SPAN 80, a lipophilic surfactant is used for 1% by volume to prepare the emulsion. Water quantity in the emulsion is varied by 5% and 10% by volume and stability study is performed. It is found that emulsion with 5% water is more stable. Thereafter, POME emulsion samples are prepared with 5% water and tested in a variable compression ratio diesel engine. The performance and emission characteristics are investigated for a set of loads and compression ratios (CR). The experimental observations show that 5% water in POME produce 3.5% lower brake thermal efficiency and 11% higher brake specific fuel consumption as compared to baseline diesel. Furthermore, the exhaust gas temperature and other emissions like oxides of carbon, oxides of nitrogen and hydrocarbon for the emulsified POME are found to be lower than the baseline diesel.

Karanja Oil

Fast depletion of fossil fuel resources forces the extensive research on the alternative fuels. Vegetable oils edible or non edible can be a better substitute for the petroleum diesel. Karanja, a non edible oil can be a potential source to replace the diesel fuel. To investigate the feasibility of Karanja oil as an alternative diesel fuel, its biodiesel was prepared through the transesterification process. The Biodiesel was then subjected to performance and emission tests in order to assess its actual performance, when used as a diesel engine fuel. The data generated for the 20, 50 and 100 percent blended biodiesel were compared with base line data generated for neat diesel fuel. Result showed that the Biodiesel and its blend showed lower thermal efficiency. Emission of Carbon monoxide, unburned Hydrocarbon and smoke was found to be reduced where as oxides of nitrogen was higher with biodiesel and its blends.

In recent years, industries have been investing to develop a potential alternative fuel to substitute the depleting fossil fuels which emit noxious emissions. Present work investigated the effect of ferrous ferric oxide nano-additive on performance and emission parameters of compression ignition engine fuelled with chicken fat methyl ester blends. The nano-additive was included with various methyl ester blends at different ppm of 50, 100, and 150 through the ultrasonication process. Probe sonicator was utilized for nano-fuel preparation to inhibit the formation of agglomeration of nanoparticles in base fuel. Experimental results revealed that the addition of 100 ppm dosage of ferrous ferric oxide nanoparticles in blends significantly improves the combustion performance and substantially decrease the pernicious emissions of the engine. It is also found from an experimental results analysis that brake thermal efficiency (BTE) improved by 4.84%, a reduction in brake specific fuel consumption (BSFC) by 10.44%, brake specific energy consumption (BSEC) by 9.44%, exhaust gas temperature (EGT) by 19.47%, carbon monoxides (CO) by 53.22%, unburned hydrocarbon (UHC) by 21.73%, nitrogen oxides (NOx) by 15.39%, and smoke by 14.73% for the nano-fuel B20FFO100 blend. By seeing of analysis, it is concluded that the doping of ferrous ferric oxide nano-additive in chicken fat methyl ester blends shows an overall development in engine characteristics.

The growing demand of diesel power generators in Iran has led to air pollution. Hence, it is necessary to ascertain the level of performance and emissions of the diesel power generators fueled with biofuels. For the first time, in this study, the effect of biodiesel from waste cooking oil and diesel fuel blends (B0, B20, B50, B80 and B100) on the performance (brake power, brake torque, BSFC, brake thermal efficiency and exhaust gas temperature) and emission characteristics (CO and NOx) of a diesel power generator model CAT3412 was investigated. The experiments were conducted at rated engine speed 1530 rpm and various engine loads (25%, 50%, 75% and 100%). The results of the study showed an increase in brake power, brake torque, BTE and NOx emission and a reduction trend in BSFC and CO emission at higher engine loads for all the biodiesel-diesel blends. In addition, the research results indicated that B20 and B50 fuel blends in terms of performance emission characteristics could be recognized as the potential candidates to be certificated for usage in the diesel power generator.

Abstract Continuous demand for energy in order to provide to an ever-increasing global population calls for use of or integration of other alternative sources of fuel other than fossil fuels. Many countries all over the world use vegetable oils blended with neat diesel as alternative and using these biofuels can help alleviate lessen the emissions releases on the environment as well as the country’s dependency on fossil fuels. In the Philippines Coconut Methyl Ester (CME) is the primary vegetable oil used, however in this study we used four other vegetable oils which are RCO (Refined Corn Oil), RPO (Refine Palm Oil), JFO (Jahtropa Filtered Oil) and JME (Jathropa Methyl Ester) in order to investigate the possibility of their use in diesel engines. A 6.3 kW single-cylinder, four stroke cycle, direct injection engine was used for the study. This kind of engine is typically used in the Philippines for different purposes such as backup power for households, for boats, pumps and for agriculture use. The specific fuel consumption of the biodiesel blends compared to neat diesel fuel ranged from −15% to 15% with RCO and JME having higher SFC and JFO and RPO having lower SFC. Fuel conversion efficiency of the varied from −12% to 12% with JFO and RPO having higher efficiency and RCO and JME having lower efficiency. The power of the varied from −7% to 6% with RPO having lower power output, JFO having higher power output and JME and RCO having similar power output to neat diesel fuel. At full load condasition Neat Diesel Fuel blended with 15% Refined Palm Oil showed the greatest improvement in SFC while Neat Diesel Fuel blended with 10% Jathropa Filtered Oil showed the best power output.

Suitability of vegetable oil as an alternative to diesel fuel in compression ignition engines has become attractive, and research in this area has gained momentum because of concerns on energy security, high oil prices, and increased emphasis on clean environment. The experimental work reported here has been carried out on a turbocharged direct-injection multicylinder truck diesel engine using diesel fuel and jatropha methyl ester (JME)-diesel blends. The results of the experimental investigation indicate that an increase in JME quantity in the blend slightly advances the dynamic fuel injection timing and lowers the ignition delay compared with the diesel fuel. A maximum rise in peak pressure limited to 6.5 per cent is observed for fuel blends up to 40 per cent JME for part-load (up to about 50 per cent load) operations. However, for a higher-JME blend, the peak pressures decrease at higher loads remained within 4.5 per cent. With increasing proportion of JME in the blend, the peak pressure occurrence slightly advances and the maximum rate of pressure rise, combustion duration, and exhaust gas temperature decrease by 9 per cent, 15 per cent and 17 per cent respectively. Although the changes in brake thermal efficiencies for 20 per cent and 40 per cent JME blends compared with diesel fuel remain insignificant, the 60 per cent JME blend showed about 2.7 per cent improvement in the brake thermal efficiency. In general, it is observed that the overall performance and combustion characteristics of the engine do not alter significantly for 20 per cent and 40 per cent JME blends but show an improvement over diesel performance when fuelled with 60 per cent JME blend.

This paper investigates the opportunity of using almond oil as a renewable and alternative fuel source. Different fuel blends containing 10, 30, and 50% almond biodiesel (B10, B30, and B50) with diesel fuel (B0) were prepared and the influence of these blends on emissions and some performance parameters under various load conditions were inspected using a diesel engine. Measured engine performance parameters have generally shown a slight increase in exhaust gas temperature and in brake specific fuel consumption and a slight decrease in brake thermal efficiency. Gases investigated were carbon monoxide (CO) and oxides of nitrogen (NOx). Furthermore, the concentration of the total particulate and the unburned fuel emissions in the exhaust gas were tested. A blend of almond biodiesel with diesel fuel gradually reduced the engine CO and total particulate emissions compared to diesel fuel alone. This reduction increased with more almond biodiesel blended into the fuel. Finally, a slight increase in engineNOxusing blends of almond biodiesel was measured.

Palm Oil Methyl Ester (POME) is a very promising alternative renewable biofuel. This is because it has a better cetane number and a comparable lower calorific value with respect to its competitors. However, due to difference in molecular composition and hence dissimilar properties, it does not perform proficiently in diesel engine with standard design and operating parameters. Therefore, a study is arranged to realize the effect of compression ratio variation on POME run in diesel engine. The load is varied from ‘no load’ to ‘full load’ with six equal intervals. During this study, standard diesel injection timing is maintained unaffected. The study conveys that at higher compression ratio, POME causes reduction in brake fuel consumption and thereby increases the engine efficiency. The increase in compression ratio also causes smoother combustion, lower ignition delay with early heat release than diesel operation. The detrimental emission quantities in the form of carbon monoxide, oxides of nitrogen and hydrocarbon emissions are also cut down with presence of POME in the diesel engine at high compression ratio. Thus, POME can be regarded as a good alternative fuel for diesel engine for locomotive applications.
