Evaluación de las emisiones de óxidos de nitrógeno en un motor de combustión interna ciclo diésel utilizando una mezcla diésel- queroseno mediante protocolo IM 240

Abstract

The main project aims to investigate the uses of alternative fuels for diesel cycle engines, specifically mixtures of diesel-kerosene in different volumetric concentrations that allow vary the viscosity, density and cetane number. The addition of kerosene seeks to reduce the quantity of Nitrogen Oxides that is generated in the polluting emissions of this kind of engines. For this, it’s necessary to prove the performance of the engine for each fuel using and standardized cycle IM-240, which was carried out in the Centro de Transferencia Tecnológica para la Capacitación e Investigación en Control de Emisiones Vehiculares (CCICEV) of the Escuela Politecnica Nacional (EPN) located in the city of Quito. Once done the testes, we proceed to analyze the results through a statistic study that allows visualize the effects of the use for each fuel, demonstrating that, effectively, the NOx presents in the emissions are reduced. At the end, the best mixture of fuel was 80% Diesel with 20% kerosene.
