An evaluation was carried out on the effect that modifying some properties of Colombian diesel fuel, such as final boiling point (FBP), density and sulfur content, has on the emissions of particulate matter (PM). Four diesel engines with different technologies and work capacity were used for the evaluation. Different alternatives to modify the properties of commercial diesel fuel, from the fuel treatment viewpoint, as well as that of the incorporation or segregation of some of the streams from the pool at the Barrancabermeja Refinery were studied. The particulate matter was measured using a partial flow (AVL.SPC472) Constant Volume Sampler (CVS) with following the 13-step steady state European cycle and the ECE-R49 European guideline. The tests were performed at the Instituto Colombiano del Petroleo. (ICP) test cell in the city of Bucaramanga, Colombia. General tendencies show reductions of up to 25% in PM emissions when final boiling point and sulfur content are reduced. But levels of reduction vary from one engine to another depending on technology and working time. As a baseline, the emission levels of the commercial diesel fuel for each engine are used, and as a reference the results obtained are compared with the EURO I and II European standards defined for the emission levels of heavy duty engines.
