“…The greater consumption of fuel (B50) with its mixtures can be firstly correlated to the lower (B50) heating magnitude. Many authors documented that an increase was obtained in the consumption of biodiesel fuel in proportion to the content of biodiesel in mixtures and to the heating magnitude loss [4][5][6][7][8][9][10][11][12][13][14][15][16]. Labeckas and Slavinskas [17] claimed that the greater (BSFC) of mixtures can be correlated to the Lower, on mean by (12.5%) of net, heating magnitude of the rapeseed oil methyl.…”

“…The pure fuels and their (20%) mixtures with a diesel fuel were investigated at the steady-state working circumstances of the engine in a 4-cylinder, direct-injection Fiat diesel engine. Despite the two biodiesel fuels gave important decreases in CO, particulate matters and unburned HC, the nitrogen oxides rose by (11) and (7%) for the yellow grease B100 and B20, correspondingly. Igbokwe et al [6] used a two-cylinder, direct injection, four-stroke diesel engine to study the performance characteristics of using palm kernel methyl ester and blended with petro-diesel at a ratio of (20% biodiesel).…”

In this study, the sunflowers oil was utilized as for producing biodiesel via a chemical operation, which is called trans-esterification reaction. Iraqi diesel fuel suffers from high sulfur content, which makes it one of the worst fuels in the world. This study is an attempt to improve the fuel specifications by reducing the sulfur content of the addition of biodiesel fuel to diesel where this fuel is free of sulfur and has a thermal energy that approaches to diesel.20%, 30% and 50% of Biodiesel fuel were added to the conventional diesel. Performance tests and pollutants of a four-stroke single-cylinder diesel engine were performed. The results indicated that the brake thermal efficiency a decreased by (4%, 16%, and 22%) for the B20, B30 and B50, respectively. The increase in specific fuel consumption was (60%, 33%, and 11%) for the B50, B30, and B20 fuels, respectively for the used fuel blends compared to neat diesel fuel. The engine exhaust gas emissions measures manifested a decreased of CO and HC were CO decreased by (13%), (39%) and (52%), and the HC emissions were lower by (6.3%), (32%), and (46%) for B20, B30 and B50 respectively, compared to diesel fuel. The reduction of exhaust gas temperature was (7%), (14%), and (32%) for B20, B30 and B50 respectively. The NOx emission increased with the increase in biodiesel blends ratio. For B50, the raise was (29.5%) in comparison with diesel fuel while for B30 and B20, the raise in the emissions of NOx was (18%) and...

“…And these esters have similar characteristics when compared with diesel, even it could be passed down in diesel or piston engines in its scrap or raw form with or without alterations [6][7]. Esterificaton is done to reduce the viscosity, surface tension and density so that fuel injection is made comparable with diesel [8]. In several countries some of the substitutes for diesel fuels are Rapeseed methyl ester, Jatropha methyl ester and Pon-gamia methyl ester.…”

The objective of the present study is to analyze the emission and performance characteristics at different compression ratio in VCR diesel engine using pumpkins seed. Bio diesel is prepared by trans-esterification process in biodiesel plant. Blends (20%, 40% and 60%)of pumpkin seed biodiesel and diesel blends are prepared and test were conducted at the load conditions (3-12 kg) The enforcement criterias like exhaust emissions, brake thermal efficiency( BTE) and Brake specific fuel consumption ( BSFC) been assessed and analyzed. And experimental results shows BSFC is same for diesel and biodiesel blends and at higher loads, 40% biodiesel blend has efficiency closer to the diesel, NOX emission in biodiesel blends have same at different loads, CO2 emissions gradually increases with increasing load.

“…As emissões veiculares carregam em sua composição várias substâncias que podem causar efeitos negativos na saúde humana, animal e vegetal, como deterioração do património e recursos naturais (Teixeira et al, 2016). Nesse contexto, muito se estuda sobre o desenvolvimento de novas tecnologias, que visem reduzir as taxas de emissões de poluentes, para cumprir com as legislações que vêm se tornando cada vez mais rigorosas, e manter, no mínimo, o padrão de eficiência dos motores atuais (Chaichan, 2018).…”

RESUMO-A demasiada utilização de combustíveis fósseis acarretou em diversos problemas ambientais, que impactam diretamente a vida dos seres vivos, implicando na criação e adoção de legislações rígidas. Faz-se necessário estudos que visem a substituição daqueles por fontes limpas e renováveis, que não afetem a eficiência e aplicabilidade dos processos. Assim, o hidrogênio tornou-se uma alternativa interessante por poder ser obtido de fontes renováveis, inesgotáveis e não poluentes. Assim, esse trabalho propõe a simulação da reforma a vapor de etanol sob níquel, objetivando a formação de hidrogênio. O software Ansys Fluent foi utilizado, e variáveis temperatura e proporção vapor/etanol foram avaliadas. Pode-se perceber que o aumento da razão molar vapor/etanol desfavorece a ocorrência da reação que ocorre em maior extensão.
