“…is limits its economic competitiveness compared to low-cost production of diesel obtained from petroleum [4,5]. Accordingly, many studies have been conducted in recent years in order to identify low-cost raw oil sources such as used vegetable oil, animal waste fats, unrefined vegetable oils, or fish waste from fishing activities [6][7][8][9].…”

Amazon sailfin catfish (Pterygoplichthys pardalis) is considered one of the greatest threats to the biodiversity of continental aquatic systems, causing serious economic and environmental problems in the regions. In this work, the production of biodiesel from Amazon sailfin catfish biomass oil is studied. The physical and chemical properties of biofuel produced were evaluated under the specifications of the European standard EN-14214 by using gas chromatography-mass spectrometry, infrared spectroscopy, and atomic absorption spectrometry analyses. The results show that the biodiesel complies with all the specifications of the standard, except the content of polyunsaturated methyl esters. The yields obtained from oil and biodiesel were 9.67 and 90.71% (m/m), respectively. The methyl ester concentrations study identified 17 components where 47.003% m/m corresponded to methyl esters with saturated chains, whereas 34.394% m/m was attributed to monosaturated methyl esters and the remaining (18.624% m/m) to polysaturated methyl esters. Finally, mineral analysis by atomic absorption showed the absence of heavy metals Cd, Ni, and Pb, as well as low concentrations of Ni, Fe, Cu, and Zn, demonstrating that the quality of the fuel is not compromised. The study indicates the feasibility of manufacturing biodiesel using Amazon sailfin catfish biomass oil as a low-cost raw material. It represents an environmental option to mitigate a global problem of atmospheric pollution, and at the same time, it shows a commercial alternative to reduce the ecological impact caused by this fish in the diverse ecosystems to which it has spread. In addition, the great adaptability of this fish provides the possibility of a profitable process to have very high rates of reproduction and growth, allowing the generation of large amounts of biomass for the production of biodiesel.

“…Upendra Rajak et al. [7] investigated performance characteristics of spirulina microalgae biodiesel at different loading conditions on four stroke water cooled direct ignition single cylinder compression engine and observed that there is a reduction in BTE, exhaust gas temperature (EGT), NOx and smoke emission and also found that using 20 % spirulina blend increases specific fuel consumption and carbon di-oxides (CO 2 ) emission.…”

In the present investigation raw oil (jatropha, soybean, and waste cooking fuel) has analyzed to prove its suitability as an alternative fuel in compression ignition (CI) engines. The blends of high vegetable oils with diesel are created and analyzed experimentally. The raw oil is blended with diesel in varying proportion (from 20 % to 50 %) using raw vegetable oil (100 %). Two sets of experiments are conducted for each fuels blends, one for performance analysis & other for emission test. The analysis has been performed for pure diesel and diverse blends of Jatropha-diesel, Soybean-diesel and waste cooking oil-diesel at compression ratio (CR) of (16.5). The performance and emission characteristic for each raw oil-diesel blends are investigated and the comparison results are presented. The result reveals that B20 blends of all biodiesel have shown very close values of Brake Thermal Efficiency (BTE) at all loading.

“…The accuracy of the measurement apparatus used in the experimental works can be calculated from the analysis of uncertainties of the equipments. In fact, the uncertainties have been principally revealed because of the calibration of the devices, observation by the researcher, environmental conditions, apparatus and system of the experiment progress techniques [66]. From this perspective, the uncertainty values of made use of the instruments in the present study such as exhaust gas emission sensors, temperature sensor, smoke meter, etc.…”

Alcohols have been known as influential alternatives for the utilization in the compression-ignition (CI) engines. In contrast to lower-order alcohols such as methanol-C1 and ethanol-C2, long-chain alcohols (higher-order alcohols) have a hopeful future for CI engines. Pentanol-C5 or amyl alcohol, regarding its affirmative chemical and physical properties, is a type of higher alcohol that can be obtained from biomass resources and hence it has to be evaluated as an alternating and sustainable fuel candidate in diesel engine applications. The objective of this work is to explore the engine performance and exhaust emission characteristics of a CI engine running on 1-pentanol/diesel fuel mixtures. For this aim of the experimental research, three different blends were created by infusing various ratios (10, 20, and 30% by volume) of 1-pentanol into pure diesel with implementing the splash-blending method to acquire the binary blends of Pt10, Pt20, and Pt30. The tested fuel samples were used in a single-cylinder diesel engine coupled with a generator. The influences of a next-generation alcohol addition to the diesel upon the engine performance along with exhaust emission levels of the tested engine were meticulously researched at six different engine loads (0, 0.4, 0.8, 1.2, 1.6, and 2 kW) with a stable speed (3000 rpm). The infusion of alcohol into the diesel fuel declined cetane number as well as the lower calorific value of the fuel blends. As a result of the study carried out, it was observed that the brake specific fuel consumption (BSFC) increased between 4.46-11.78% averagely as the ratio of 1-pentanol in the mixtures increased while brake thermal efficiency (BTE) and exhaust gas temperature (EGT) dropped up to 6.75% and 6.69%, respectively owing to the lesser energy content of the 1pentanol. When the test engine operating with binary blends, unburned hydrocarbon (HC) and carbon monoxide (CO) emissions were obtained to be higher than that of conventional diesel fuel due to the higher latent heat of vaporization (LHV) of 1-pentanol resulting in a cooling impact in the cylinder, leading descending trend in the efficiency of the combustion. Besides, the addition of 1pentanol to diesel caused the mitigation in smoke emission by 77.37-89.60%, carbon dioxide (CO2) by 13.06-30.83%, and nitrogen oxides (NOX) by 13.43-41.61% on an average as compared to diesel fuel. Overall, it has been shown up that 1-pentanol might be successfully utilized as an oxygenated fuel additive to diesel fuel, however in a minimum concentration of 1-pentanol, i.e., Pt10 blend has provided luminous outcomes in terms of mitigating the EGT, smoke opacity, and especiallyNOXemissions, however at the expense of boosting in the emissions of CO and HC.
