“…In general, it can be seen that at lower loads, the BSFC of the CI engine is higher and then decreases before increasing again very slowly. Similar trends in BSFC were reported by Gumus and Kasifoglu [40] and [62] for all blends investigated (B10, B20, B50, B100 and diesel) at different load conditions. One of the explanations for a decreasing BSFC with an increase in load is because of a higher increase in brake power, as compared to fuel consumption [19].…”

Biodiesel is one of the alternative fuels which is renewable and environmentally friendly and can be used in diesel engines with little or no modifications. In the present study, experimental investigations were carried out on the effects of biodiesel types, biodiesel fraction and physical properties on the combustion and performance characteristics of a compression ignition (CI) engine. The experimental work was conducted on a four-cylinder, four -stroke, direct injection (DI) and turbocharged diesel engine by using biodiesel of waste oil, rapeseed oil and corn oil and normal diesel. Based on the measured parameters, detailed analyses were carried out on cylinder pressure, heat release rate and brake specific fuel consumption (BSFC). It has been seen that the biodiesel types do not result in any significant differences in peak cylinder pressure and BSFC. The results also clearly indicate that the engine running with biodiesel have slightly higher in-cylinder pressure and heat release rate than the engine running with normal diesel. The BSFC for the engine running with neat biodiesel was higher than the engine running with normal diesel by up to 15%. It is also noticed that the physical properties of the biodiesel affects significantly the performance of the engine.

“…The results obtained with the addition these types of biodiesel in diesel highlight the importance of the modifications introduced in the fuel properties: composition change with the introduction of oxygen, reduced energy content and increased viscosity. These changes, in turn, causes a depletion in the combustion process which can be associated with an increase efficiency of the thermal engine (BUENO et al 2009(BUENO et al , 2011. Thus, data have been reported where the thermal efficiency of the engine is increased with the addition of biodiesel (BUENO et al, 2009;AGARWAL et al, 2001, ALI et al, 1995 or remained virtually unchanged RAKOPOULOS et al (2007).…”

ABSTRACT:The use of renewable fuels, such as the biodiesel, can ease the demand of fossil fuel for the power generation and transportation fields in rural area. In this work, the performance impact of the application of castor oil biodiesel is evaluated with an automotive and a stationary diesel engine. The application of B20 and B10 biodiesel blends and pre-heated net biodiesel is considered. The viability of the employment of B10 and B20 blends to mobility and power generation was observed from dynamometric bench tests, where this blends performed similar to fossil diesel. With the pre-heated net biodiesel, however, a brake torque loss and a specific consumption increase were observed with relation to diesel fuel. KEYWORDS:Biodiesel, Castor Oil, Diesel Engine, Dynamometric Bench Tests. IMPACTO DA UTILIZAÇÃO DO BIODIESEL DO ÓLEO DE MAMONA NO DESEMPENHO DE MOTORES DIESELRESUMO: A utilização de fontes renováveis de energia, como o biodiesel, pode coibir o uso dos combustíveis fósseis empregados na geração de potência e no transporte rural. Neste trabalho, avaliou-se o impacto operacional da aplicação do biodiesel de mamona em um motor diesel automotivo e em um motor diesel estacionário de médio porte, estudando-se as alterações provenientes da utilização deste biocombustível puro preaquecido e, como misturas, B10 e B20. Observou-se em bancada a viabilidade de aplicação das misturas B10 e B20, tanto em mobilidade quanto em geração de trabalho elétrico, pois as mesmas obtiveram desempenho similar ou superior ao do diesel mineral. Contudo, resultados inferiores de torque de frenagem e um aumento no consumo específico foram obtidos com o biodiesel de mamona preaquecido B100 com relação ao óleo diesel. PALAVRAS-CHAVE:Biodiesel, Óleo de Mamona, Motor Diesel, Ensaio Dinamométrico.

“…Blending biodiesel with diesel retains many of the advantages of biodiesel while overcoming some of its limitations. It is observed that by blending biofuel with fossil fuels, the combustion efficiency is enhanced and a cost-reduction in the distribution system is obtained [5][6][7].…”

Abstract. Solid-liquid equilibria for binary mixtures of {Methyl palmitate (1) + Naphthalene (2)} were measured using differential scanning calorimeter (DSC). Simple eutectic behaviours for this system are observed. The experimental results were correlated by means of the NRTL, Wilson, UNIQUAC and ideal models. The root-mean-square deviations of the solubility temperatures for all measured data vary from 0.5477 K (for UNIQUAC model) to 3.34K; the deviation depend on the model used. The best solubility correlation was obtained with UNIQUAC model and this observation confirms previous results.
