Popis: | EROL, Dervis/0000-0002-3438-9312; dogan, battal/0000-0001-5542-4853; WOS: 000401593000043 Ethanol which is considered as an environmentally cleaner alternative to fossil fuels is used on its own or blended with other fuels in different ratios. In this study, ethanol which has high octane rating, low exhaust emission, and which is easily obtained from agricultural products has been used in fuels prepared by blending it with gasoline in various ratios (E0, E10, E20, and E30). Ethanol-gasoline blends have been used in a four-cylinder four-stroke spark ignition engine for performance and emission analysis under full load. In the experimental studies, engine torque, fuel and cooling water flow rates, and exhaust and engine surface temperature have been measured. Engine energy distribution, irreversible processes in the cooling system and the exhaust, and the exergy distribution have been calculated using the experimental data and the formulas for the first and second laws of thermodynamics. Experiments and theoretical calculations showed that ethanol added fuels show reduction in carbon monoxide (CO), carbon dioxide (CO2) and nitrogen oxide (NOx) emissions without significant loss of power compared to gasoline. But it was measured that the reduction of the temperature inside the cylinder increases the hydrocarbon (HC) emission. (C) 2017 Elsevier Ltd. All rights reserved. |
