Biodiesel, a derivative of vegetable oils and animal fats, is used nowadays as an alternative renewable and sustainable fossil fuel. In this work, the investigation of manufacture, characterization, and results of biodiesel blends are carried out using two important feedstock’s, sunflower oil and ricebran oil on engines. For the collective advantageous of sunflower oil and ricebran oil, the two biodiesels are combined together and the mixture is analysed to assess the engine performance and emission characteristics. NaOH catalyzed transesterification process is used for producing the Biodiesels A 4.4 kW, four-stroke, single-cylinder and direct fuel injection diesel engine is used for measuring physic-chemical with full load and varying speed conditions and using the specifications of ASTM D6751 standard, the properties are compared. It is observed that the Biodiesel mixtures produce a low brake torque and high brake-specific fuel consumption (BSFC) in addition to the reduction of CO and HC emissions. NOx, however, is reduced considerably with the improvement of brake thermal efficiency. The Performance analysis indicates that the mixture of sunflower oil and ricebran oil improves performance and emission characterizes over sunflower oil and ricebran oil biodiesel when they are unmixed..

In the present work, the combustion, performance and emission characteristics of sunflower oil, sunflower methyl ester and its blends were studied and compared with diesel by employing them as fuel in a single cylinder, direct injection, 4.4 KW, air cooled diesel engine. Emission measurements were carried out using five-gas exhaust gas analyzer and smoke meter. The performance characteristics of Sunflower oil, Sunflower methyl ester and its blends were comparable with those of diesel. The components of exhaust such as HC, CO, NOx and soot concentration of the fuels were measured and presented as a function of load and it was observed that the blends had similar performance and emission characteristics as those of diesel. NOx emissions of sunflower oil methyl ester were slightly higher than that of diesel but that of sunflower oil was slightly lower than that of diesel. With respect to the combustion characteristics it was found that the biofuels have lower ignition delay than diesel. The heat release rate was very high for diesel than for the biofuel.

In present scenario researchers focusing the alternate sources of petroleum products. Based on this, current research work focused the emission study of its characteristics and potential as a substitute for Diesel fuel in CI engines. Current research biodiesel is produced by base catalyzed transesterification of rice bran oil is known as Rice Bran Oil Methyl Ester (Biofuel). In this research various proportions of Biofuel and Diesel are prepared on volume basis. It is used as fuels in a four stroke single cylinder direct injection Diesel engine to study the performance and emission characteristics of these fuels. Varieties of results obtained, that shows around 50% reduction in smoke, 33% reduction in HC and 38% reduction in CO emissions. In result discussion a different blends of the brake power and BTE are reduced nearly 2 to 3% and 3 to 4% respectively around 5% increase in the SFC. Therefore it is accomplished from the this experimental work that the blends of Biofuel and Diesel fuel can successfully be used in Diesel engines as an alternative fuel without any modification in the engine. It is also environment friendly blended fuel by the various emission standards.

In current years, many researches have been worked to find new sources of alternative fuels. In this situation, the water hyacinth will be a new source for bioethanol. In this study, bioethanol extracted from water hyacinth is blended with diesel (5-BED, 5% bioethanol and 95% diesel v/v) and has been used to experimentally investigate the diesel engine performance and emission. The response surface methodology (RSM) technique with three engine operating variables like (i) Load, (ii) Compression ratio (CR) and (iii) Fuel Injection pressure (FIP) has been implemented to evaluate diesel engine performance using bioethanol diesel blend. The equations were obtained for Brake power (BP), Brake mean effective pressure (BMEP), Brake thermal efficiency (BTHE), and NO emission by using quadratic polynomial

Experimental study has been carried out to investigate performance parameters, emissions, cylinder pressure, exhaust and wall temperatures at different engine speeds and different percentage of EGR using sunflower and jojoba/diesel (B20) blend in comparison to diesel fuel. Sunflower oil and B20 were selected for the study because of its being widely used in Egypt and world. Tests were conducted for three different fuels with different engine speeds. Also, series of tests were conducted at same previous conditions with different percentage of exhaust gas recirculation (EGR) rates from 0 to 12% of inlet mass of air fresh charge. Results indicate that sunflower or B20 blend gives lower brake thermal efficiency, brake power, brake mean effective pressure, and higher BSFC due to lower heating value compared to diesel fuel. Sunflower or B20 blend gives lower NOX concentration due to lower gases temperature. Sunflower or B20 blend gives higher wall/exhaust temperatures due to incomplete combustion inside engine cylinder. Sunflower or B20 blend gives higher CO and CO2 concentrations due to higher carbon/hydrogen ratio. The position of maximum pressure change for diesel fuel is earlier than for sunflower and B20 blend. The results show that sunflower and B20 blend are promising as alternatives fuel for diesel engine. One of the main advantages of vegetable oil is not requiring significant modification of existing engine hard wares. On contrast, the main disadvantages of biodiesel fuels are high viscosity, drying with time, thickening in cold conditions, flow and atomization characteristics.
