Abstract
A long-term test (100,000 km) was carried out in order to evaluate the performance of five (5) blends of diesel and palm biodiesel (B5, B10, B20, B30 and B50) compared to fossil diesel (B0) . The tests used several buses of the mass transport system in the city of Bogota operating under normal conditions at 2600 meters above sea level and an average temperature of 14°C. The results showed that the performance and fuel consumption of the buses using the biodiesel blends were very similar to those of the buses using only diesel fuel (the control buses). The vehicles' opacity was measured every 10,000 km and the results showed that the buses using diesel- biodiesel blends had lower opacity values than the buses using fossil diesel fuel. This was confirmed by the results of the on-road emissions test which showed reduction in CO2 and particulate matter emissions. Mechanical inspections of the injection systems of the vehicles were performed every 50,000 km and showed that there were no anomalies and the wear-out of the different components was similar for all the tested vehicles. It was also found that packaging and O-rings of all vehicles were in good condition. Se llevó a cabo una prueba de larga duración (100.000 km/bus) para evaluar el desempeño de cinco (5) mezclas de diesel-biodiesel de palma (B5, B10, B20, B30 y B50) con diesel fósil (B0), bajo condiciones normales de operación de buses articulados del sistema de transporte masivo de Bogotá, a una altura de 2600 metros sobre el nivel del mar y a una temperatura promedio de 14°C. Los resultados obtenidos mostraron que el desempeño y consumo de combustible de los buses que utilizaron las mezclas diesel-biodiesel es muy similar al de los buses que utilizaron diesel fósil. La opacidad de los vehículos, evaluada cada 10.000 km, mostró que los buses que utilizan mezclas con biodiesel de palma presentan menores valores de opacidad que los que operaron con diesel. Lo anterior se corroboró con los resultados de las pruebas de emisiones en ruta, que mostraron reducciones en las emisiones de CO2 y material particulado. Inspecciones mecánicas realizadas a los sistemas de inyección de los buses cada 50.000 km mostraron que no se presentan irregularidades y que el desgaste fue similar para todos los vehículos evaluados. Adicionalmente se encontró que los empaques y sellos (o-rings) de todos los vehículos se encontraban en buenas condiciones.
