The metropolitan area of the Aburrá Valley. AMVA, have been presenting emergencies for PM2.5 in recent years and that indicates the need of strategies of intervention to ensure cleaner air. It has been proposed to add the catalyst agent Green Plus (GP) to diesel fuel, which, according to previous experiences in several countries reduces the specific fuel consumption and lowers pollution emissions. To demonstrate this at the local level, a pilot project was undertaken between December 2016 and April 2017, subjecting 25 diesel operated vehicles to continuous work during three months with fuel enhanced with GP under carefully monitored conditions, including determination of fuel mileage and static test emissions at 30, 60 and 90 days, comparing the results to a baseline initial month in which normal fuel (LB) was used. Significant reductions in specific emissions of CO, particulate matter (PM), EC and OC were obtained, as well as increases in fuel efficiency, which leads to economic attractiveness and avoided CO2 emissions.
