Particulate Filter


Diesel Particulate Filter (DPF) catches and stores exhaust soot (some refer to them as soot traps) to decrease emissionsParticulate Filter (DPF) catches and stores exhaust soot (some refer to them as soot traps) to decrease emissions from diesel cars.

  • Due to their limited capacity, this trapped soot needs to be periodically removed or burned off to regenerate the diesel particulate filterparticulate filter.
  • A diesel particulate filter maintains large exhaust gas particles by forcing the gas particulate filter maintains large exhaust gas particles by forcing the gas to flow the filter
  • Diesel particulate filters go through a regeneration process that has the capability to remove soot and lower filter pressure
  • Maintenance freed DPF can burn a large particle quantity until it decomposes enough to pass through the filter; however often particles clump
