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 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 Indeed, the development of alternative fuels for use in internal combustion engines has become an essential requirement to meet the energy demand and to deal with the different problems related to fuel. The research in this domain leads to the identification of adverse fuel properties and for their solution standard limits are being defined. This paper outlines an investigation of performance and combustion characteristics of a 4-stroke diesel engine using different cymbopogon (lemongrass) - diesel fuel blends. 10% to 40% cymbopogon is mixed with diesel fuel and tested for performance characteristics like brake specific fuel consumption and brake thermal efficiency. To obtain emission characteristics smoke density in the terms of HSU has been measured. In result, it has observed that there is an increase of 5% in brake thermal efficiency and 16.33% decrease in brake specific fuel consumption. Regarding emission characteristics, a 12.9% decrease in smoke emission has been found.

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.

In this present paper, an attempt has been made to examine the performance and emission characteristics of a single cylinder diesel engine fueled with blends of mixed biodiesel (Thevetia peruviana, Neem, Jatropha, Pongamia). Experiments were conducted with various blends of mixed biodiesel in CI engine for different loads. The results show that lower brake thermal efficiency and higher brake specific fuel consumption were obtained with mixed biodiesel blends when compared with diesel. Lower the value of CO and HC and higher the value of CO2 emissions were determined for mixed biodiesel blends compared to that of diesel. Also, higher in NOx and lower smoke opacity were found compared to diesel.

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.

This study aims to find the optimum performance and emission characteristics of single cylinder variable compression ratio (VCR) engine with different blends of Annona methyl ester (AME) as fuel. The performance parameters such as specific fuel consumption (SFC), brake thermal efficiency (BTE), and emission levels of HC, CO, Smoke, and NO x were compared with the diesel fuel. It is found that, at compression ratio of 17: 1 for A20 blended fuel (20% AME + 80% Diesel) shows better performance and lower emission level which is very close to neat diesel fuel. The engine was operated with different values of compression ratio (15, 16, and 17) to find out best possible combination for operating engine with blends of AME. It is also found that the increase of compression ratio increases the BTE and reduces SFC and has lower emission without any engine in design modifications.

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
