“…For all tested fuel samples, increased engine load resulted in a greater increase in CO emissions, until a maximum load was reached except at 100% biodiesel (B 100 ), which increased slightly. Increased engine speed resulted in a sharp decrease in CO emissions until the maximum speed was reached, except at B 100 , which decreased slightly 43 – 45 . The maximum CO emissions value was 369 ppm at the maximum loading stage using 100% diesel fuel (B 0 ), while the minimum CO emissions was 69 ppm at the minimum loading stage using 100% biodiesel fuel (B 100 ).…”

Fossil fuels are the main energy sources responsible for harmful emissions and global warming. Using biodiesel made from waste deep-frying oil as an alternative fuel source in diesel engines has drawn great attention. This biodiesel is produced using the transesterification process and blends with mineral diesel at Faculty of Agriculture Saba Basha, Alexandria University, Egypt. The turbocharged diesel engine of a Kubota M-90 tractor was tested. The objectives of this work are to test tractor as a source of power in the farm using waste deep-frying oil biodiesel to utilize waste frying oils (WFO) in clean energy production on the farm and determine the best engine loading stages to maximize engine efficiencies for different fuel blends and reduce the environmental impact of gas emissions from tractor diesel engines in the farms. The experiment design was factorial, with two factors, where the first was the engine load (0%, 25%, 50%, 75%, and 100%) and the second was fuel blend (0%, 5%, 20%, and 100% biodiesel), and the effects of loading stages and biodiesel percentage on engine performance indicators of engine speed, power take off torque, power take off power, brake power, brake mean effective pressure, brake thermal efficiency, brake specific fuel consumption, and gas emissions were studied. The experimental results indicated that engine load percentage and fuel blend percentage significantly affected all studied characters, and the best engine loading stages were between 25 and 75% to maximize engine efficiency and minimize the specific fuel consumption and gas emissions. Increasing the biodiesel percentage at all loading stages resulted decreasing in Engine brake power (BP), brake thermal efficiency, Power take-off (PTO) torque, and brake mean effective pressure and increases in brake specific fuel consumption. Increasing the engine load resulted in decreases in O2 emissions and increases in CO2, CO, NO, and SO2 emissions. Increasing the biodiesel percentage in the blended fuel samples resulted in increases in O2 and NO emissions and decreases in CO2, CO, and SO2 emissions. The use of biodiesel with diesel fuel reduces the environmental impact of gas emissions and decreases engine efficiency.

“…Similarly, the results showed a decrease in the rate of heat release for biodiesel blends compared to diesel for all tested modes of operation. It was observed that in the highest engine operating mode, the HRR curves The reduction in HC emissions is mainly due to oxygen molecules in the chemical structure of the fuel, which produces complete combustion inside the chamber [23]. Due to this fact, biodiesel with the percentage of sunflower oil has the lowest HC emissions, since its oxygen content is higher compared to palm oil blends.…”

This study investigated the influence of different biodiesel blends produced from residual sunflower oil and palm oil from agroindustry liquid waste on the characteristics of the combustion process, performance, and emissions in a single-cylinder diesel engine. For the analysis of the combustion process, a diagnostic model was developed based on the cylinder pressure signal, which allows the calculation of the heat release rate, the accumulated heat rate, and the temperature in the combustion chamber. This is to assess the influence of these parameters on engine emissions. The experiments on the diesel engine were carried out using five types of fuel: conventional diesel, two biodiesel blends of residual palm oil (PB5 and PB10), and two biodiesel blends formed with palm oil and sunflower oil residues (PB5SB5 and PB10SB5). The engine was running in four different modes, which covered its entire operating area. Experimental results show that the in-cylinder pressure curves decrease as the percentage of biodiesel in the fuel increases. Similarly, the results showed a decrease in the heat release rate for biodiesel blends. The diagrams of the accumulated heat release curves were larger for fuels with higher biodiesel content. This effect is reflected in the thermal efficiency of biodiesel blends since the maximum thermal efficiencies were 29.4%, 30%, 30.6%, 31.2%, and 31.8% for PB10SB5, PB5SB5, PB10, PB5, and diesel, respectively. The emission analysis showed that the blends of biodiesel PB5SB5 and PB10SB allowed a greater reduction in the emissions of CO, CO2, HC, and opacity of smoke in all the modes of operation tested, in comparison with the blends of biodiesel PB5 and PB10. However, NOx emissions increased. In general, biodiesel with the percentage of residual sunflower oil does not cause a significant change in the combustion process and engine performance, when compared to biodiesel that includes only residual palm oil.

“…Due to negative impact of fossil fuels, environmental is damaging and there is a need for alternatives to green fuels. Biodiesel production from renewable sources is considered a green and eco-benign for substitution of petro-diesel (Abukhadra et al, 2019a;Abukhadra et al, 2019b;Aghel et al, 2019;Allami et al, 2019;DeMarini et al, 2019;Dhanasekar et al, 2019;Du et al, 2019;Elkelawy et al, 2019;Hazrat et al, 2019;Silveira et al, 2019).…”

Present study was designed to produce biodiesel using Cola lepidota seed oil in the presence of clay catalyst. The extraction was done in petroleum ether and oil was characterized using Fourier Transform Infrared Spectrophotometer (FTIR) and scanning electron microscope (SEM) techniques. The biodiesel produced, was characterized for specific gravity, kinematic viscosity, American petroleum index (API) gravity, flash point, cloud point, aniline point and diesel index. The result from FTIR shows that there was C-N stretching aliphatic amine at 1072.46 cm-1, CH2X alkyl halides at 1226.77 cm-1, C-C stretching (in ring) aromatics at 1442.80 cm-1, N-O asymmetric stretching nitro compounds at 1527.67cm-1, C=C stretching α, β unsaturated esters at 1712.85 cm-1, C-C stretching aromatics at 2924.18 cm-1, O-H stretch or free hydroxyl alcohols or phenols at 3610.86 cm-1. The oil yield was 1.76%. The result revealed that the biodiesel showed the following properties; specific gravity (0.862 g/cm3), viscosity (4.8mm2/sec), API (30.24 oC), flash point (80 oC), cloud point (-2 oC), aniline point (68 oC) and diesel index (1.424). These values were within the recommended limits of American Standard for Testing Material (ASTM D6751). This study reveals that C. lepidota oil is a veritable precursor for biodiesel production and other industrial applications.
