A method and device for monitoring and controlling the regeneration of a particle filter in an exhaust gas duct of an internal combustion engine which has a three-way catalytic converter downstream of the particle filter, wherein the particle filter is regenerated by oxidative burning of the particles during a regeneration phase, wherein oxygen consumption is balanced, directly or indirectly, during the regeneration phase via the temporal variation of a first signal of a first lambda probe, which is arranged upstream of the particle filter, in comparison to the temporal variation of a second signal of a second lambda probe, which is arranged downstream of the particle filter. A lambda value of &#x3bb;=1 is set downstream of the three-way catalytic converter during the regeneration of the particle filter by means of lambda control and the second lambda probe which is arranged downstream of the three-way catalytic converter.

A procedure for determining the proportion of components of a fuel mixture, which is boosted with a fuel pump, and a device for implementing the procedure are suggested. A measure for the power input of the fuel pump is detected, with whose aid the proportion of components of the fuel mixture is determined. By proceeding according to the invention a special sensor, which is susceptible to components of the fuel mixture can be waived.
