  • The amount of soot on the DPF helps to determine how often and when to start or stop a regeneration. A regeneration is triggered when the filter needs to be cleaned. The filter is cleaned by burning off all the diesel particles (soot).
  • 158 Particle filter; soot mass calculated 13.19 g 159 Particle filter; soot mass measured 3.13 g 160 Particle filter; time since last regeneration 18239 s Also, how would you read the regen time of 18239 s, surely that can't mean seconds can it? Why are there two values for the soot mass and what do they mean? Very interesting stuff. The first one is a low-load mode, with high soot emissions and therefore with high contribution to the DPF charge. The second one is a medium-load mode, in which the balance of soot charge versus spontaneous soot regeneration leads to a slow DPF charging, the temperature at the exhaust manifold being high enough to permit active regeneration.

“Ash vs. Soot” Carbon-based soot, formed by incomplete combustion of fuel, is not the only thing which collects in DPFs. Metal-based impurities caused by burning small amounts of engine oil forms ‘ash’ which builds up slowly builds up over time in the DPF.
