• Abstract:

  The volume of pre filter sold

  during last five years have led 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 J905 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 Scanner Electron

  Microscopy (SEM) in order to understand the

  influence of wax in water separation performance

  and effects in injector nozzle.
