“…Some of the important parameters includes: brake specific fuel consumption, brake effective power, thermal efficiency, in-cylinder pressure and heat release rate. Many researchers have investigated the performance characteristics of engines running with biodiesel and its blends and compared it against its performance when running with normal diesel [15], [16], [17], [18], [19]. In the following sections some important works have been reviewed to identify gaps in the knowledge in combustion and performance characteristics of the CI engine running with biodiesel blends to justify the present work.…”

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.

“…Higher thermal efficiency with pure biodiesel was reported by Murrilo et al (2007). 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.…”

“…2 demonstrates that the cut-off ratio and compression ratio variations influence the fluid work significantly. Gogoi and Baruah (2010) found that for all the fuels the power increased with compression ratio. These variations are similar for all three used fuels, especially diesel and B20 fuels.…”

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.

“…Alternative fuels can be less expensive to use not just in terms of the fuel itself but also in terms of a longer service life. Lot of research have been done on the performance on the engine using alternative fuel [1][2][3][4][5][6][7][8][9]. Ramadhas et al [1] developed a thermodynamic model to analyze the performance characteristics of the CI engine fueled by biodiesel and its blends and concluded that with the increase in compression ratio peak pressure, peak temperature and brake thermal efficiency are increased.…”
