Resumen
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.
