“…Biodiesel can be used as a blending component or a direct replacement for diesel fuel in internal combustion engines (Demirbaş, 2009). In contrast to petrodiesel, the advantages of biodiesel are lower emission of CO due to a better combustion, a better lubricating effect on engines, nonsulfur emission, non-flammable, non-explosive with a flash point of 423 K for biodiesel as compared to 337 K for petrodiesel, portability, ready availability, renewability, higher combustion efficiency, lower sulfur, higher cetane number, higher biodegradability, and non-aromatic content (Phan and Phan, 2009;Meng et al, 2008;Keskin et al, 2010;Balbasi et al, 2011;Basha et al, 2009). Another and important advantage of biodiesel is its domestic origin that would help a country's dependency on imported petroleum (Keskin et al, 2008).…”

In this experimental study, biodiesel production from waste oils (trap grease), which were obtained from an oil separator, was carried out by using sulfuric acid as the catalyst and esterification process. The main variables involved in the esterification process, including methanol/waste cooking oils ratio, amount of acid catalyst, reaction time, and reaction temperature, were analyzed. Because the waste cooking oils contain high free fatty acid above 65%, the esterification process has been preferred. Methanol was used as alcohol in this process because of its low cost, and sulfuric acid was preferred as the catalyst because it gives very high yields in alkyl esters. Experiments have been performed to determine optimum conditions for this esterification process in different molar ratios, catalyst amounts, reaction times, and reaction temperatures. The optimum experimental conditions, which were obtained from the esterification process, were methanol/waste cooking oils ratio 9/1, with 9 wt% sulfuric acid catalyst, reaction time 120 min, and reaction temperature 60 ı C. The yield of biodiesel was 93.98% at optimum esterification process. Biodiesel and its blends with diesel were characterized for their physical properties referring to a substitute for diesel fuel. The results show that blends with a percentage of the biodiesel below 40 vol% had their physical properties within EN590 standard, which indicated that these could be used in engines without a major modification.

This article investigates the utility of waste tyre oil as a potential source of partial replacement of diesel fuel. The experimental study of engine parameters such as performance, emissions, along with combustion characteristics of tyre oil blends with cerium oxide (CeO2) and without CeO2 nano additive in a four‐stroke single‐cylinder water‐cooled compression ignition engine was conducted without any engine adjustment. Tyre oil was blended with diesel fuel at the volumetric proportions of 5, 10, 15, and 20%. These experimental results reveal that B5 blend has increased Brake thermal efficiency compared to other blends and nearer to diesel fuel at full load. The emissions of Hydrocarbon (HC), smoke are lower than diesel fuel by 3, 3.22% for B5 blend of full load. If CeO2 nano additives are doped with tyre oil blends in such case the B5D85 + CeO2 100 ppm blends were increased in efficiency of 2.85% and emissions like HC, CO, Smoke are decreased by 3, 1.33, 7.7%, respectively compared to diesel. From the experimental results, B5D85 + CeO2 100 ppm fuel blend is the best fuel ratio for a CI engine for increased efficiency, reduced emission and better combustion. Hence, the tyre oil with CeO2 nano additives is a suitable alternative fuel for CI engine.

“…At the full load, the brake thermal efficiency for the JME fuel observed was 24.80%, whereas it was 26.34% and28.45% for the JME2S5W and JME2S5W100CNT fuels respectively. HARISH VENU et al [19] have found the influence of Alumina (Al2O3) nanoparticle on various injections [20] have found the performance, combustion and emission characteristics of a variable compression ratio engine using Cerium Oxide Nanoparticles and Carbon Nanotubes as fuel-borne nanoparticles additives in Diesterol (diesel-biodiesel-ethanol) blends. The addition of CERIA and CNT in Diesterol blend increases the cylinder gas pressure when comparing with the neat Diesterol blends.…”

This paper aims to communicate the diesel engine performance and emission characteristics fueled with biodiesel and to reduce NOx emission. Biodiesel is a possible alternate fuel to reduce The dependency on fossil fuel and can replace petroleum fuels. The essence of additives in Biodiesel like Al 2 O 3 , CNT, CeO 3 , ZnO 2 , TiO 2 , CoO2, CuO, FeO 2 , and others with respect to properties, performance and emission are depicted. The literature reviews spotlights, addition of Nano-metallic and non-metallic additives in biodiesel radically improve the properties of trans esterified esters and later contribute to secondary atomization thereby enhancing combustion of this esters resulting in better performance with reduced emissions.
