This paper deals on bio-fuel, consisting of used sunflower oil and transesterified - used sunflower oil blended with diesel. They are prepared and tested as a fuel in a direct injection (DI) single cylinder four stroke diesel engine. The main fuel properties of these fuels are measured, the engine performance characteristics are investigated and compared with that of diesel fuel. Fuels are separately prepared, blended and tested for determining the characteristics and combustion in a single cylinder diesel engine. The main fuel properties such as the specific gravity, density, flash and fire points of the blended fuels are measured. The engine performance is investigated and compared with that of diesel fuel. The experimental results showed that the specific gravity of the hybrid bio-fuels is decreased and close to that of diesel fuel. The experimental results also showed that the engine efficiency is closer to the values obtained from the diesel fuel. It is found that among the various blends, transesterifed used sunflower oil with diesel, gives better efficiency. In addition it is found that, the blend of diesel with used sunflower oil gives the lowest fuel consumption as compared to that of other blended fuels.

The Individual

The article deals with verification of a diesel fuel and two fuel mixtures blends with different amounts of the bio-component using the model single-cylinder engine without the additional equipment for treatment of exhaust gases. This combustion diesel engine served for measuring the performance characteristics of the model single-cylinder engine and the individual emission components in order to assess the use of these blends of liquid paraffinic diesel fuel in practice and to meet current and forthcoming European legislation and to fulfil the commitments by 2020. A detailed chemical analysis was performed in case of all the tested paraffinic diesel fuels.

Biodiesel Fuels

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.
