Abstract :

In this study, the performance values of a small spark ignition engine which is widely used in the agricultural sector were determined in trials with mixing bioethanol to gasoline in certain proportion. Bio-ethanol was mixed by 5%, 10, 15 and 20 percent into gasoline which is widely used in the world. This mixture ratios were used in the engine without any changes. Then, ethanol production costs and sales values were calculated for different raw materials (sugarbeet, wheat, barley, corn,potatoes). The most suitable raw material for bioethanol was determined by taking into account of the trial results and cost calculation. In the engine trials; The highest engine effective power was obtained working with gasoline, the least engine power was obtained from E20. While bioethanol amount increase in mixture fuel, reduction in effective power also increased. The highest specific fuel consumption was obtained in E20 and the lowest value obtained in gasoline. Calculation of the costs of raw materials for bioethanol production and quantities of the raw materials necessary for the production of 1 liter of bioethanol production costs by taking into account the raw material for sugarbeet 1.1 TL l^-1, for wheat 1.74 TL l^-1, for barley 2.16 TL l^-1, for corn 1.32 TL l^-1 and for potatoes 2.1 TL l^-1 were determined. Agricultural characteristics of raw materials, given the economic characteristics and properties of bio-ethanol, the most suitable raw material for bioethanol are sugar beet then corn and wheat respectively. But wheat is recommended for the most suitable raw material for bio-ethanol for our country than that of sugar beet and maize in terms of the more advantageous cultivation properties.
