Evaluación del comportamiento y emisiones en un motor de combustión interna utilizando una mezcla Diésel-Queroseno

Abstract

That research experimentally assesses the effect on performance and emissions of a compression ignition engine using the mixture of diesel with kerosene. Taking advantage of the miscibility between these two fuel, were performed blends in volumetric proportions of 5%, 10%, 15%, 20%, 25% and 30% of kerosene in diesel, identified as D5K, D10K, D15K, D20K, D25K and D30K respectively. To characterize the two fuels and their six mixtures were measured their physicochemical properties in a laboratory guided by a set of norms. To determine the change in the mechanical performance of the vehicle were performed dynamic tests of torque and power based in the norm SAE J-1349 in the chassis dynamometer LPS 3000. While, to assess the effect in the emissions of the polluting gases, were performed static tests of opacity and particulate matter PM2.5 established by the NTE INEN 2202 standard. As experimental result, it was determined that mixtures can be made until a concentration D20K without modifying the fuel supply system and that all mixtures with kerosene allowed reduce the level of opacity and concentration of particulate matter PM2.5, while power and the torque decreases in smaller percentage.
