Method for adjusting an oxygen flushing mass of a catalytic converter and for controlling an air-fuel ratio of an internal combustion engine taking into account the detected oxygen flushing mass |
| abstract |
The invention relates to a method for adjusting an oxygen flushing mass of a catalytic converter (11) and for controlling an air-fuel ratio AFR of an internal combustion engine (10), comprising the steps: i. calculating an oxygen flushing mass O5 from a quantity of air flowing into the internal combustion engine (10) and a quantity of fuel flowing into the internal combustion engine (10) and by forming an integral from an increase in a quantity of oxygen stored in the catalytic converter (11) from a point in time t1 at which an air-fuel ratio AFR begins to lean until a point in time t2 at which an oxygen content measured by a lambda sensor (13) arranged downstream of the catalytic converter (11) exceeds a limit value, and ii. performing a catalytic converter flushing process by enriching the air-fuel ratio AFR, taking into account the calculated oxygen flushing mass O5. |
