Apparatus for post-treatement of exhaust gases und method for the regeneration of the apparatus

摘要

Particles are trapped in parts of particle filter with an integrated catalytic phase, (16) with at least one chemical favoring an exothermic reaction to oxidize the reducing elements in the exhaust gas. Fuel is injected at one or more crank position(s), where the amount and position are chosen to raise the concentration of the reducing elements in the exhaust gas to a level set as a function of their temperature.
