Biofuels are one of the most sought-after renewable energy sources to overcome the current energy crisis in the world. Diesel blended with esters derived from oils has shown appreciable results for its use in compression ignition engines. In this work, B20 (20% biodiesel + 80% diesel by volume) fuel blend comprising 80% diesel and 20% biofuel extracted from waste cooking oil is used as a fuel. Two different metallic oxide nanoparticles (NPs), namely, cerium oxide (CeO 2 ) and aluminium oxide (Al 2 O 3 ) each having size of 30 nm, are dispersed in B20 biodiesel blend and used to investigate their combined influence on engine combustion. Experiments are conducted to study the engine exhaust emissions of a single cylinder four-stroke diesel engine running at constant speed of 1,500 rpm with varying engine loads. Experiments are carried out with B20 fuel and adding mixtures of CeO 2 and Al 2 O 3 nanoparticles in 50-30, 40-40 and 30-50 ppm, respectively, to B20 biodiesel blend. Responses recorded are the emissions of CO, HC, CO 2 , NOx and smoke. The results reveal that, on adding the nanoparticles, the engine observed a smooth combustion with reduction in the exhaust emissions compared to neat B20 biodiesel operation. B20 blend with 50 ppm of CeO 2 and 30 ppm of Al 2 O 3 nanoparticles showed lower exhaust emissions compared to other fuel blends. For the best fuel blend, CO, HC, NOx and smoke are reduced by 57.3%, 22.3%, 24.3% and 7.36%, respectively, compared to neat B20 operation.

“…the Brake specific fuel consumption for the biodiesel -diesel blends seems to be high than the pure diesel , this because of decrease the calorific value and increase viscosity of the biodiesel blends as compared with the pure diesel ,This caused a large volume of fuel droplets after atomization which lead unproperly mixing with the air [9].The brake specific fuel consumption (BSFC) for the (B20% + D80%) B20 is seems to be lower than B10 , B30, B40 and B50 . A suitable oxygen content and density that creates a complete combustion in (B20% +D80%) blends [7]. The increase in the specific fuel consumption (bsfc) is about (5.85%, 7.48% , 10.55 % , 14.3% , and 16.5) for (B20 , B10 , B30 , B40 and B50) ratios as compared with pure diesel at full load 80 kg and engine speed 1100 rpm.This results are in agreement with [7][8].…”

“…The advantage of biodiesel is that can be using in a diesel engine without any modification, and lower toxicity compared with the diesel fuel. The disadvantages of biodiesel fuel are higher fuel consumption and increasing in nitrous dioxide (NO X) emission than diesel fuel [7]. The current work is aiming at the comparative assessment of performance, emission and combustion characteristics of a four-cylinder diesel engine alternatively fuelled with biodiesel and its 10%, 20%,30%, 40% and 50% blend with pure diesel.…”

Biodiesel fuel is a liquid biofuel produced by chemical process form new and used phytogenic oils, animal fats. Biodiesel fuels can be utilization alone or mixing with the pure diesel at different proportion. In the present work a diesel engine type (FIAT) , four cylinder, variable speed, direct injection was operated by sunflower oil methyl ester , biodiesel at different blend ratio . five different ratio of biodiesel blends 10%, 20%, 30%, 40%, and 50% by volume is used in this study and compared with using of pure diesel at variable loads and variable engine speed. The effect of biodiesel additive to pure diesel on the performance and emission characteristics. Adjust the engine speed at 1100 rpm by means of the engine tachometer and digital tachometer, and reduce the load gradually until the engine speed increased to 1900 rpm automatically by increments of 200 rpm. The BSFC for B20 It seems less than the other ratio of biodiesel blends, and the BTE of biodiesel blends is lower than the pure diesel but the B20 having high BTE in comparison with the other biodiesel- diesel mixtures. the UHC and CO emission for B20 is less than the biodiesel blends and pure diesel, but the NOX emission for B20 is lower than the other biodiesel blends and higher than pure diesel. The present work shows the B20 relatively is a better performance and combustion characteristic than that biodiesel blends ratio.

“…Over the years diesel motors became one of the main sources of power generation around the world, due to the efficiency and economy, being used in transport, agriculture, etc. However, with technological advancement and population growth, the high consumption and rapid depletion of fossil fuels compel the energy sector to adapt to this new reality [1,2]. In this way, also aiming at the significant reduction of the emission of polluting gases and, consequently to contribute to the minimization of the environmental impacts on the planet, several energy sources were studied and implemented over the years [3].…”

To produce biodiesel, one of the most important factors is the quality of the oil used in the production. However, other factors such as price and availability should also be taken into consideration. Chicken wastes oil shows a very promising option for this sector, since it comes from a waste. The aim of the present study was a methodology for extraction and characterization of chicken wastes oil for production of biodiesel by ethylic transesterification, besides presenting the characterization and optimization of the process variable of the production of biodiesel the applying RSM involving CCD. The investigation was performed following characterization parameters for the oil were evaluated: viscosity, density, acidity index, moisture of the sample, refractive index, and saponification index. For biodiesel were evaluated viscosity, density, acidity index and ester content. An optimum point was reached for the production of chicken biodiesel where the concentration of the catalyst is 2.1% by mass, the oil/ethanol ratio is 1:5,5 and the reaction temperature of 30 ?C, at that point was achieved a 95% conversion. At the optimum point obtained from the statistical technique for a p-value of 0,05 the results found for the physical-chemical characterization of biodiesel are found in the ANP standards.
