  • Regeneration control method for a particle filter
    Patent number: 8020376
    Abstract: A regeneration control method for a particle filter of an internal combustion engine exhaust line determines operating data items of the particle filter, wherein the data items are at least one representative inside temperature T(t) of the filter at a time t, regenerates the filter by increasing the temperature thereof above a first combustion temperature threshold of a soot contained in the filter, and computes a time-varying parameter dinst(t) representative for the amount of energy produced at the time t by the regeneration process. The method further calculates a weighted parameter Dinst weight(t), which is at least partially defined by the function of dinst(t)*Gtemp (t) or Gtemp (t) and varying in time (t) according to the representative temperature T(t).

  • Method for regenerating a motor vehicle particle filter and system for controlling regeneration of such a filter
    Patent number: 7536854
    Abstract: A method for regenerating a motor vehicle particle filter that uses a mechanism for regenerating the filter when a load value exceeds a predetermined threshold. Further, a parameter representing operating conditions of the regenerating mechanism is calculated, and the operating conditions of the regenerating mechanism are controlled on the basis of the parameter.
