METHOD FOR THE REGENERATION OF A PARTICLE FILTER, AND INTERNAL COMBUSTION ENGINE WITH PARTICLE FILTER

摘要

A method and an internal combustion engine for the regeneration of a particle filter includes periodic regeneration phases, where a regeneration is performed by virtue of the soot particles that have been deposited in the particle filter being burned off. During the operation of the internal combustion engine, the reactivity of the soot deposits is determined on the basis of a characteristic map previously established empirically for different engine operating ranges of the internal combustion engine.

1. A method of regenerating a particle filter of an internal combustion engine, comprising the steps of:
performing, during periodic regeneration phases, regeneration in which soot deposits in the particle filter are burned off, the soot deposits comprising soot particles deposited in the particle filter; and determining, during operation of the internal combustion engine, a soot reactivity of the soot deposits on the basis of a characteristic map saved in a memory.
