Artigo:

The volume of pre filter sold during last five years have lead us to evaluate the root cause of it. Initially, it was verified the entire volume of pre filter commercialized increased 9 times from 2005 to 2018. The costumer’s complaints are related to premature filter plugging and change interval under specification as informed by maintenance manual. Analysis have performed according to SAE J1839 and SAE J 905 standards in order to evaluate water separation and filtering performance. It was confirmed a water separation performance reduced, including several cases near 60% with low mileages. Besides, it was noted sludge and wax at filtering media surface in umpteen samples. On the other hand, a comparison between field components – with commercial Diesel S10 B10 and diesel S10 B10 with high oxidation stability – was done and it was confirmed the filtering media life with high oxidation stability keeps the change interval according specification. The trend with diesel S10 B15 with low and high stability was accomplished too. The media was analyzed with MEV in order to understand the influence of wax in water separation performance and effects in injector nozzle.
