Incidencia del Contenido de azufre en las emisiones contaminantes en un vehículo encendido por compresión con Sistema de Inyección CRDI.

Abstract

This research deals with the "Incidence of sulphur content in pollutant emissions in a Great Wall pick-up truck model Wingle 7, Year 2020 which power system works by making compression with Common rail direct injection”; the objective is to fulfil the purpose set out above by using three types of fuels: Premium Diesel purchased in the city of Quito with a sulphur content of 43.9 [ppm], : Premium Diesel purchased in the city of Guayaquil with a sulphur content of 18.4[ppm] and a volumetric mixture of 50% of the two fuels with a sulphur content of 31.1 [ppm]; the analysis of the fuels was carried out in the Laboratory of Fuels, Biofuels and Lubricants oils (LACBAL) and also we realize test results in the Technology Transfer Centre for Training and Research in Vehicle Emissions Control (CCICEV) and we also used or university laboratories belonging that official belong to the National Polytechnic School, these laboratories are accredited under the national standards NTE INEN. The study was carried out using static tests of free acceleration, as a result in opacity and particulate matter values, and IM-240 cycle tests using the LPS 3000 dynamometer, which helps to observe pollutant emissions that are generated in each type of fuel allowing to evaluate emission factors and fuel efficiency. Once the tests were completed, it was observed that the results obtained comply with the requirements established in the national standards NTE INEN 2 207 and the European standards EURO V. In addition, the study shows that in Guayaquil and Quito marketize low-sulphur diesel, lower than 50 [ppm] and the sulphur has a direct impact and positive in the process of reduction of pollutant emissions and particulates matter.
