Abstract
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.
