Uso de etanol carburado en motores Diesel
This work was performed in the Agricultural Mechanics Shop of the Universidad Nacional of Colombia in Palmira. A two-cylinder, 1260 cm3 diesel engine with a compression ratio of 23:1 was fueled by a dual system formed by its injection system for diesel oil and a carburation system for ethanol and ethanol-water blends. In a first test, m e injection advance was varied between 18 and 26 o BTDC (Before Top Dead Center) to determine the optimum injection advance in the original engine and the engine fueled with the dual system. According to the maximum power point, 20 and 22° BTDC were selected as the optimum advances. In the second test, the engine was operated at variable load and speed with four fuels (diesel oil, ethanol and ethanol-water blends with 20 and 40% water) with the next results: me speed increased 10%, the maximum power increased 6.5%, the maximum torque increased 3.73%, since the original engine to the dual system fueled with the ethanol- water blend 40 % water, me maximum replacement of diesel oil was in the high speed range where 32 % diesel oil was replaced by ethanol, and over fueling the engine with carburated ethanol was justified in the high speed range. Power, speed, torque and fuel replacement increased in this range.
