Quantitative Analysis of Particulate Matter in Diesel Using a Microfiltration System and a Laser Particle Counter

Diesel is one of the most widely used fuels in Ecuador due to its availability and relatively low cost. However, its extensive use poses significant challenges related to pollution and engine efficiency. This study addresses diesel microfiltration as a technique to improve fuel quality by reducing the amount of contaminant particles present. The results were evaluated using cleanliness codes according to ISO 4406, which provide a standard framework for assessing diesel quality before and after the microfiltration process. It is demonstrated that microfiltration can significantly improve diesel quality according to the parameters established in the Worldwide Fuel Charter (WWFC), meeting the cleanliness requirements specified by ISO 4406, thereby having a positive impact on diesel engine efficiency and lifespan.
