Abstract
Dual-fuel combustion using biofuels is a potential technique both to reduce pollutant emissions and to increase overall efficiency in compression ignition engines. This work aimed to study experimentally the performance and emissions of a single-cylinder engine fueled with diesel-ethanol mixtures under the dual-mode dual-fuel technology. The tests were carried out at points of the Non-Road Steady Cycle (NRSC), which is used in the homologation process of agricultural tractors in Brazil. Ethanol was port-fueled injected using an electronic central unit while diesel was direct-injected by a mechanical fuel pump system. An injection trade-off considering the fuel´s energy content helped to achieve the best mixture proportion. In-cylinder pressure analysis was carried out in order to understand the combustion development and behavior. Gaseous (NOx, HC, CO and CO2) and smoke emissions were assessed for each dual-fuel test condition. Diesel-ethanol dual-fuel combustion showed an interesting potential to maintain satisfactory efficiency levels and to reduce NOx and smoke pollutant emissions. The use of ethanol from sugarcane in diesel engines represent an advantage to reduce the carbon footprint and to beneficiate the Brazilian energy matrix.
