The present study examines the effect of silicon dioxide (SiO2) nano-additives on the performance and emission characteristics of a diesel engine fuelled with soybean biodiesel. Soybean biofuel was prepared using the transesterification process. The morphology of nano-additives was studied using scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy-dispersive X-ray spectroscopy (EDS). The Ultrasonication process was used for the homogeneous blending of nano-additives with biodiesel, while surfactant was used for the stabilisation of nano-additives. The physicochemical properties of pure and blended fuel samples were measured as per ASTM standards. The performance and emissions characteristics of different fuel samples were measured at different loading conditions. It was found that the brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC) increased by 3.48–6.39% and 5.81–9.88%, respectively, with the addition of SiO2 nano-additives. The carbon monoxide (CO), hydrocarbon (HC) and smoke emissions for nano-additive added blends were decreased by 1.9–17.5%, 20.56–27.5% and 10.16–23.54% compared to SBME25 fuel blends.

Experimental tests have been carried out to evaluate the performance and emissions characteristics of a diesel engine when fuelled by blends of 25% vegetable oil with 75% diesel fuel, 50% vegetable oil with 50% diesel fuel, 75% vegetable oil with 25% diesel fuel, and 100% vegetable oil, compared with the performance, emissions characteristics of 100% diesel fuel. The series of tests were conducted and repeated six times using each of the test fuels. 100% of ordinary diesel fuel was also used for comparison purposes. The engine worked at a fixed speed of 1500 r/min, but at different loads respectively, i.e. 0%, 25%, 50%, 75% and 100% of the engine load. The performance and the emission characteristics of exhaust gases of the engine were compared and analyzed. The experimental results showed that the carbon monoxide (CO) emission from the vegetable oil and vegetable oil/diesel fuel blends were nearly all higher than that from pure diesel fuel at the engine 0% load to 75% load. Only at the 100% engine load point, the CO emission of vegetable oil and vegetable oil/diesel fuel blends was lower than that of diesel fuel. The hydrocarbon (HC) emission of vegetable oil and vegetable/diesel fuel blends were lower than that of diesel fuel, except that 50% of vegetable oil and 50% diesel fuel blend was a little higher than that of diesel fuel. The oxides of nitrogen (NOx) emission of vegetable oil and vegetable oil/diesel fuel blends, at the range of tests, were lower than that of diesel fuel.

Abstract: There is growing interest to study the effect of blending various oxygenated additives with diesel or biodiesel fuel on engine performance and emission characteristics. This study aims to analyze the performance and exhaust emission of a four-stroke, four-cylinder diesel engine fueled with biodiesel-ethanol-diesel. Biodiesel was first produced from crude Jatropha oil, and then it was blended with ethanol and fossil diesel in different blend ratios (B10E10D80, B12.5E12.5D75, B15E15D70, B20E20D60 and B25E25D50). The engine performance and emission characteristics were studied at engine speeds ranging from 1200 to 2000 rpm. The results show that the brake specific fuel consumption increases while the brake power decreases as the percentage of biodiesel and ethanol increases in the blend. The exhaust emission analysis shows a reduction in CO2 emission and increase in NOx emission when the biodiesel -to- ethanol ratio increases in the blends, when compared with diesel as a reference fuel.

Abstract This research investigates the effects of the addition of Fe2O3 and Al2O3 nanoparticles (30, 60, and 90 ppm) and Fe2O3-Al2O3 hybrid nanoparticles to pure diesel fuel on the combustion, performance and emission characteristics of a diesel engine. The results indicated that fuel blends improved the combustion (in-cylinder pressure and heat release rate), performance (power, fuel consumption, and thermal and exergy efficiency), and emission characteristics of the engine. The results showed that the peak combustion pressure increased by 4% and the heat release rate was improved by 15% in comparison with pure diesel with the addition of the nanoparticles. Moreover, the rate of pressure rise increased by 18% compared to pure diesel with nanoparticle additives. Based on the results, the effects of Fe2O3 fuel blends on brake power, BTE, and CO emission were more than Al2O3 fuel blends, such that it increased power and thermal efficiency by 7.40 and 14%, respectively, and reduced CO emissions by 21.2%; moreover, the blends with Al2O3 nanoparticle additives in comparison with Fe2O3 nanoparticle blends showed a better performance in reducing BSFC (9%), NOx (23.9%), and SO2 (23.4%) emissions. Overall, the Fe2O3-Al2O3 hybrid fuel blend is the best alternative if the performance and emission characteristics of the engine are both considered.

This study focuses on the conversion of chicken fat into chicken fat methyl ester (CFME) and its use in the diesel engine. Baseline fuel i.e., diesel and chicken fat biodiesel are the fuels tested to study their effect on the performance and emission characteristics of diesel engines. To enhance the performance and emission characteristics, ethanol up to 20% is added as an additive to the chicken fat biodiesel. The physiochemical properties revealed that the fuel blends properties are closer to the diesel fuel. The experimental investigations revealed that additive blended biodiesel enhanced the performance by reducing the brake-specific fuel consumption and increasing the brake thermal efficiency. Moreover, the emissions are considerably reduced by the additive blended chicken fat biodiesel. Therefore, chicken fat biodiesel can be considered as a substitute fuel to be used in the diesel engine without any modifications.

Suitable Modification

The technology for use of biodiesels (up to 20%) as alternative fuel in diesel engines has already been established. In this regard, some suitable modification of biodiesel with appropriate additives may help in increasing the biodiesel component in the biodiesel fuel blends. In order to evaluate the effects of iron nanoparticles (INP) blended palm biodiesel (PB) on the performance and emission characteristics of diesel engine, an experimental investigation is carried out in a single cylinder diesel engine. Methodically, biodiesel prepared from palm oil and commercially available nanosized INP is used in this study. Iron nanoparticles are suspended in the biodiesel in proportions of 40 ppm to 120 ppm using an ultrasonicator. The intact study is conducted in the diesel engine using the four fuel samples, namely diesel, PB20, INP50PB30, and INP75PB30, consecutively. The addition of nano-additive has resulted in higher brake thermal efficiency (BTE) by 3% and break-specific energy consumption (BSEC) by 3.3%, compared to diesel fuel. The emission levels of carbon monoxide (∼56%) and NOx (∼4%) are appreciably reduced with the addition of INP. Increase of INP in the blend from 50 ppm to 75 ppm, BTE and BSEC tend to reduce, but CO and NOx emissions are reduced.
