عنوان انگلیسی Combustion and exergy investigation of a compression ignition engine fueled with ethanol and methanol blends
چکیده انگلیسی مقاله Today, the use of hybrid fuels in internal combustion engines has been considered to decrease the level of environmental pollutants. Among the various additives used to increase the efficiency and decrease pollution of Compression Ignition (CI) engines, alcohols especially methanol and ethanol have a special place. In this work, a one-dimensional, thermodynamic and two-zone model was used to evaluate the performance and emission of a compression ignition engine using ethanol and methanol in two volumes of 5% and 10% with diesel fuel by using engineering software such as GT-Power. Also, an exergy assessment is performed to study the exergy efficiency and exergy destruction of the engine for desired cases. The results show that the use of diesel fuel with alcoholic compounds reduces the heating value of the fuel compared to the D100 as well as the maximum brake torque and power and significantly reduces the engine exhaust emissions. This reduction is at most equal to 15%, which is of particular importance with respect to pollutants such as  and CO. The exergy analysis shows that addition of alcoholic compounds such as ethanol and methanol by 5% and 10% to diesel fuel reduces braking power, it also reduces input exergy, which decreases exergy destruction and decreases the exergy efficiency by a maximum of 1.1%.
