Method for the control of the supplied air/fuel ratio of an internal combustion engine

Abstract

In a method for the control of the supplied air/fuel ratio of an internal combustion engine (1) with a catalytic converter (5) which is located in the exhaust gas line (2) with an integrated oxygen reservoir (6), it is proposed that the air/fuel ratio be controlled as a function of at least one parameter of the internal combustion engine (1), at least one parameter of the catalytic converter (5), and/or as a function of the type and amount of the exhaust gas emissions which are currently occurring, in order to optimize the relative degree of filling of the oxygen reservoir (6) which is contained in the catalytic converter (5) for favorable conversion of the exhaust gas emissions. According to the proposal, matching to the current conversion demand and the current conversion performance is enabled and thus overall improved exhaust gas conversion is implemented.
