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.

Nano Additives

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.

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.

In this contemporary era it is mandatory to increasing the usage of non edible biodiesel to replace the fossil fuels. This non edible biodiesels are produced from vegetable oils which is clean burning and renewable. This paper deals with the performance and emission characteristics on diesel engine with blends of Castor oil as biodiesel. Castor oil biodiesel is prepared by the use of adding 1% v/v H2SO4 after the transesterification process. The engine tests were performed with various blends B20, B40, B60 on a single cylinder, 4-stroke, diesel engine. The result shows Higher performance and lower emissions for B20 than the diesel and other blends. The brake thermal efficiency is higher than the diesel and CO, HC and NOX emissions were 22%, 8.4%, and 21% lesser than that of diesel.

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.

The present study examines the effect of 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. Nano-additives characterisations were done using different tests such as FESEM, XRD, EDS, etc., to study the morphology of nano-additives. For proper blending of nano-additives with biodiesel, the ultrasonication process was used. Surfactant was used for the stabilisation of nano-additives. After making all the combinations of nano fuel blends, physicochemical properties were measured as per ASTM standards. Performance and emissions readings were taken at different load conditions. It was found that with the addition of SiO2 nano-additives, brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC) was increased by 3.48-6.39% and 5.81-9.88%, respectively. Significant reduction of CO, CO2, NOx, and smoke emissions were also observed compared to baseline fule due to better combustion efficiency with the use of SiO2 nano-additive.

In this study, Biodiesel -Dimethyl Ether (BDE) and Biodiesel Ethanol (BE) were tested in a 4-cylinderdirect-injection diesel engine to investigate the performance and emission characteristics of the engine underfive engine loads at the maximum torque. The engine speed was maintained at 1500 rpm. Here the jatropha oilis used as a non edible oil to produce the biodiesel. The ethanol and dimethyl ether is used as an additive toenhance the engine combustion. The BDE 5 (biodiesel 95% and dimethyl ether 5%) , BDE 10 (biodiesel 90%and dimethyl ether 10%) BDE 15(biodiesel 85% and dimethyl ether 15%) BE5 (biodiesel 95% and ethanol 5%),BE10 (biodiesel 90% and ethanol 10%) and BE15 (biodiesel 85% and ethanol 15%) were tested in the engine.The results indicate that when compared with neat jatropha, the engine performance increased and emissionlevel decreased with adding the ethanol and diethyl ether with methyl ester of jatropha oil. In comparison withneat jatropha, the BDE5 and BE15 blends have higher brake thermal efficiency (BTE) of 12% and 13%respectively. The experimental results showed that the CO, HC emission is decreased and NOx emission isincreased for higher blends of additives. The brakes specific fuel consumption (BSFC) decreased for BDE5 andBE5 compared to other combination of fuel.DOI: http://dx.doi.org/10.3329/jme.v42i1.15941

Feed stock cost and NOX emission are the major barriers for commercialization of biodiesel. Waste cooking oil is well identified as one of the cheapest feed stocks for biodiesel production. This chapter reduces NOX emission of waste cooking oil biodiesel. Test fuel blends are prepared by mixing diesel (20 to 50 v/v%), butanol (5 v/v%), and waste cooking oil biodiesel (45 to 75 v/v%). Fuel properties of waste cooking oil biodiesel are enhanced due to addition of diesel and butanol. Brake specific energy consumption of the blends is higher than diesel fuel. Harmful emissions like carbon monoxide, nitrous oxide, and smoke opacity are lower for blends than diesel fuel. Increasing biodiesel concentration in blend also reduces hydrocarbon emission to a significant extent. The obtained results justify the suitability of proposed cheap blends for diesel engine emission reduction.
