“…Diesel and biodiesel fuels have several different properties which can decrease engine performance and increase emissions. For example, the high viscosity and surface tension of biodiesel affect atomisation by increasing the mean droplet size, which in turn increases spray tip penetration [6][7][8][9][10][11][12][13]. Considering the differences between diesel and biodiesel fuels, the optimum parameter of diesel engines may not seem suitable for biodiesel.…”

In this study, the effect of fuel injection timing on the performance of a diesel engine was investigated experimentally and analytically using diesel-biodiesel blends. Different experiments were carried out on the diesel engine at engine speeds of 1200, 1600, 2000 and 2400 rpm. The injection timing was regulated for 10, 15 and 20 degree crank angle before top dead centre. The experimental results of engine torque, brakespecific fuel consumption (BSFC), cylinder pressure, and exhaust gas temperature for fuel blends of B20, B40, and B100 at different engine speeds and injection timings were recorded. The results showed that advancing the fuel injection timing for fuel blends of B20, B40, and B100 increased engine torque by approximately 2.1%, 2.9% and 6.3%, respectively, and decreased maximum BSFC by approximately 2.7%, 3.3% and 6.6%, respectively. Then, an artificial neural network (ANN) was used to predict engine performance. The injection timing, engine speed, and fuel blends were used as input parameters whereas engine performance parameters such as engine torque, BSFC, peak cylinder pressure, and exhaust gas temperature were used as the output parameters. The results showed that an ANN is a good tool to predict engine performance.

“…Gogoi and Baruah (2010) found that blends B20, B40 and B60 present an increase in thermal efficiency compared to diesel. Raheman and Phadatare (2004) obtained higher thermal efficiency with B20 and B40. Since thermal efficiency is the ratio of power to the fuel energy input, therefore, due to increased power and less fuel energy input with biodiesel blends, the thermal efficiency is more in case of the blends which matches the present study results (Fig.…”

“…According to a review on emission data for heavyduty engines published by EPA (Environmental Protection Agency of USA 2002), from diesel to B20 (20 % biodiesel and 80 % diesel by volume), CO, HC and PM decreased by 13, 20 and 20 % respectively (Lapuerta et al 2008). Because of its reproducibility, nontoxicity and sulfur-free properties, a considerable amount of recent researches have focused on experimental performance analysis of Diesel engine fueled by various sources of biodiesel and its blends (Dasilva et al 2003;Raheman and Phadatare 2004;Ramadhas et al 2005;Usta 2005; Labeckas and Slavinskas 2006;Reyes and Sepulveda 2006;Rao et al 2007;Rehman et al 2007;Tsolakis et al 2007;Hu et al 2008). Furthermore, due to its similar physical properties to diesel fuel, there is no need to modify the engine when it is fueled by biodiesel blends (Graboski and McCormick 1998;Ramadhas et al 2004;Srivathsan et al 2008;Atadashi et al 2010;Liu et al 2011;Zhang et al 2011).…”

Because of environmental problems, it becomes necessary to develop alternative fuels that give engine performance at par with diesel. Among the alternative fuels, biodiesel and its blends hold good promises as an eco-friendly and the most promising alternative fuel for Diesel engine. The properties of biodiesel and its blends are found similar to that of diesel. Many researchers have experimentally evaluated the performance characteristics of conventional Diesel engines fueled by biodiesel and its blends. However, experiments require enormous effort, money and time. Hence, via finite-time thermodynamics simulation, an air-standard Diesel cycle model with heat transfer loss and variable specific heats of working fluid is analyzed to predict the performance of Diesel engine. The effect of compression ratio, cut-off ratio and fuel type on output work and thermal efficiency is investigated through the model. The fuels considered for the analysis are conventional diesel, rapeseed oil biodiesel and its blend (20 % biodiesel and 80 % diesel by volume). Numerical simulations showed that the output work and thermal efficiency of the engine decrease with increase of cut-off ratio for all fuels. Also, the model predicts similar performance with diesel and biodiesel blend which means that the biodiesel blend (20 % biodiesel and 80 % diesel by volume) could be a good alternative and eco-friendly fuel for conventional Diesel engines without any need to modify the engine.

“…The reason can be ascribed to the nearness of oxygen in Karanja biodiesel atomic structure. Raheman and Phadatare [6] discovered Karanja biodiesel mix (B20-B100) in a diesel motor lessen CO discharge (73-94%), smoke thickness (20-80%) and 26% in normal NOx outflow than diesel fuel due to the total burning of the biodiesel mix fuel. Shi et al [7] found that the utilization of biodiesel-diesel-ethanol mixes diminishes particulate issue outflows by 30% and a general decrease in complete hydrocarbon yet somewhat (5.6-11.4%) increases the NOx emissions.…”

Abstract:The growing human population and rapid industrialization have caused an increase in the demand for energy around the world. The rapid depletion of fossil fuels and overdependence on petroleum based fuels have made it inevitable for the search for alternative fuels. The fossil fuels are also causing huge damage to the environment and it cannot be denied that vehicles are the main source of it. Pollutants emissions from the vehicle have disturbed the ecological system. The best alternative currently is the biofuels which have the ability to reduce engine emissions. The main focus area of this review is to discuss the important role biofuels can play to reduce the greenhouse gases in the environment and their effects on I.C. engines. Biofuels have the potential to reduce greenhouse gases by 80%. So, they are viable alternatives to be used for vehicles.
