Determinación del porcentaje optimo de biodiésel y diésel filtrado a 2850 msnm, para reducir la opacidad de un motor con sistema CRDI, y reducir el impacto ambiental

Abstract

This research aimed to determine the ideal mixture percentage between biodiesel and filtered diesel through different proportions of the fuels to reduce opacity levels in trucks with a Common Pipe Direct Injection (CRDI) system in Quito city. Three percentages of the mixture of Biodiesel (B) to B5, B10, and B15 were defined. The opacity was taken into account by using a model PLS 3000 automotive dynamometer with the filtered diesel and the ambiguity with the commercial diesel to refer to its reduction in the four vehicles with the CRDI system. For commercial diesel filtering, the pumped diesel filtering machine was used, which uses Racor PFD10/30 filters, reaching a level of purity through the cleanliness of the code according to the International Organization for Standardization (ISO) 14/13/9. For the statistical analysis of opacity, the Analysis of Variance (ANOVA) and the TUKEY method were performed for the difference in means, resulting in at least two types of mixtures being different, and the treatment that minimizes the percentage of opacity is the mixture of filtered diesel & B15. It is concluded that filtering commercial diesel improves fuel quality, considerably reducing the opacity rate in the analyzed vehicles. Consequently, if filtered diesel were commercialized throughout Ecuador, combustion would be enhanced, and polluting emissions would be reduced. For tests carried out in the laboratory or on dynamometer benches, it is recommended to have precision in the measurement equipment to have an effectiveness of measurement.
