“…In addition, fuel blends with an oxygen percentage of more than 2.37% showed a slight increase in( ) compared to diesel. This may be attributed to the higher density and viscosity of these blends causing poor atomization and incomplete combustion, that dominated over the gain in heating value due to which the fuel consumption increased slightly [30,33,38,39]. From these results, it may be realized that fuel blends having an oxygen content between 1.975%-2.370% showed lower BSEC than diesel.…”

“…Furthermore, other disadvantages of using biodiesel are its lower volatility, heating value, energy density, rate of heat release, and rate of pressure rise, engine power losses, longer combustion duration, and higher brake specific fuel consumption (BSFC). Chauhan et al [30] observed lower brake thermal efficiency (BTE) and higher BSFC along with lower HC, CO, CO2, and smoke emissions, and higher NOx emissions for jatropha biodiesel blends compared to diesel fuel. Other than that, Altaie et al [31] reported that enriched biodiesel blended fuel shows lower brake torque and higher BSFC than diesel fuel due to lower calorific values.…”

In this study, 18 soapnut biodiesel-diesel blends along with soapnut oil as an additive in some blends were prepared and used in a diesel engine to investigate the effect of oxygen content in the fuel blends on engine performance and emission characteristics. Considering the large variations in the oxygen content of these fuel blends, the obtained results were demonstrated based on varying fuel oxygen content. Findings showed that the best engine performance was achieved with a fuel oxygen content in the range of 1.8%-3.0%, whereas the best engine emissions were obtained with a fuel oxygen content in the range of 0.71%-2.37%. Hence, considering both engine performance and emissions, the optimal zone of fuel oxygen content was found to be in the range of 1.80%-2.37%. Thus, it can be concluded that biodiesel blended fuels having an oxygen content in the aforesaid range can be successfully used in diesel engines with comparable engine performance and emissions to those using diesel fuel. Nevertheless, further research is required to reduce the fuel oxygen content to this optimal range if the blends consist of higher biofuel components. Besides that, the use of suitable additives in the biodiesel blended fuels may be a viable option to achieve the said purpose, which needs further research.

“…The NO x emissions substantially increase with temperatures. In many experiments, there has been decrease in nitrogen oxides emissions with biodiesel perhaps because in-cylinder temperature is lower which can be due to lower calorific value of the fuel [7].In single cylinder engine running with palm [8,9] and jatropha biodiesel [10,11], the reported results indicate lower brake powers and higher brake specific fuel consumptions (BSFC) [12].…”

Abstract-As we know from year to year the emission standards are become stringent due to Global Warming Effect. It is difficult for the developing countries like India to meet such stringent emission standards as it involves expensive technologies. In this crisis, there is a need to search for the costeffective methods to reduce emissions from IC engines. Previous research shows that Biodiesel fueled diesel engines emit less CO 2, HC and Smoke emissions than Diesel fueled Engines. In this study, a dual biodiesel blend, mixture of two different kinds of biodiesel namely palm and jatropha with diesel was considered for evaluation in a single cylinder DI diesel engine after going through physical properties analysis. The objective of present work is to investigate experimentally the effects of Dual Bio-diesel blends on performance and emissions of VCR DI constant speed Diesel Engine under various loads and Compression Ratios. Performance and Emission Tests were conducted on VCR Diesel Engine running at a constant speed of 1500 r.p.m. under various loads and compression ratios. Results showed that Brake power (BP) is increased by 1.5% for the test fuel D90PB5JB5 compared to Diesel. BSFC of D90JB5PB5 Test Fuel is almost same as that of conventional Diesel fuel whereas D80JB10PB10 test fuel showed a slight increase in BSFC at all loads when compared to fossil Diesel fuel. Brake Thermal Efficiency is maximum for D90JB5PB5 Bio-diesel blend and it is minimum for D80JB10PB10 when compared to diesel. It was observed that CO and HC emissions were decreased when Engine is running with dualbiodiesel blends when compared to conventional diesel fuel.

“…Table 1. Properties of vegetable oil compared to petro-diesel (Altın et al, 2001;Pugazhvadivu & Jeyachandran, 2005;Senthil Kumar et al, 2005;Agarwal & Agarwal, 2007;Murugesan et al, 2009;Misra & Murthy, 2011;Chauhan et al, 2012;Bousbaa et al, 2012;Yahya & Norhisyam, 2012 As shown in Table 1, the kinematic viscosity, cetane number, higher heating value, density and flash point of the alternative fuel for the CI engine are all substandard to petro-diesel. Based on this concern, this research has grouped the alternative fuels for the CI engine ranging from vegetable oil to higher viscous fuels (HVFs).…”

“…Many techniques have been used by researchers worldwide to improve the CI engine fueled by HVF. Among these are the use of HVF as an additive to petro-diesel fuel (Chauhan et al, 2012;Agarwal & Agarwal, 2007) to reduce the consumption of petro-diesel; preheating the HVF (Pugazhvadivu & Jeyachandran, 2005;Senthil Kumar et al, 2005) to level its viscosity; and adjusting the injection timing (Ye & Boehman, 2012) to inject the fuel at the highest possible pressure and temperature to increase the combustion efficiency. These techniques produce better results than a CI engine fueled with HVF; however, performance was still lower than when fueled by petro-diesel.…”

This paper investigates the in-cylinder air flow of a compression ignition (CI) engine modified by a guide vane swirl and tumble device (GVSTD) where the number of GVSTD vanes was varied to optimize its dimension to improve the CI engine performance using higher viscous fuel (HVF). Hence, eleven 3D CI engine models were developed; a base model and 10 GVSTD models, via SolidWorks. Computational fluid dynamics (CFD) were performed by utilizing ANSYS-CFX and simulated under motored conditions for two continuous complete cycles. The results are presented of the simulation of in-cylinder pressure, turbulence kinetic energy (TKE) and velocity during the fuel injection period until expansion. The recorded increments from six vanes of GVSTD were about 1.3%, 0.2% and 22% of the above results. Hence, this paper concludes that GVSTD has the potential to improve CI engine performance using HVF.
