Patent ID: 7210284

Claim:
A process for the control of the supplied air/fuel ratio of an internal combustion engine with a catalytic converter which is located in the exhaust gas line, with an integrated oxygen reservoir, comprising controlling the air/fuel ratio as a function of at least one parameter of the internal combustion engine, at least one of one parameter of the catalytic converter, and as a function of the type and amount of the exhaust gas emissions which are currently occurring, in order to optimize the speed for adjustment of the admission or discharge of oxygen in the oxygen reservoir contained in the catalytic converter for favorable conversion of the exhaust gas emissions during transient operation of the internal combustion engine and after deviations from the air/fuel ratio λ=1 utilizing data from a first exhaust gas probe positioned upstream from the oxygen reservoir, a second exhaust gas probe positioned at least partially in the oxygen reservoir and a third exhaust gas probe positioned downstream of the oxygen reservoir.
