    摘要: A method for controlling an internal combustion engine in which in each case the lambda value is ascertained by evaluating a measuring signal of a lambda probe. In this context, two combustion periods of the internal combustion engine are compared to each other. In the two combustion periods, in a single cylinder the lambda value is induced once in the direction of a lambda increase and once in the direction of a lambda decrease.

    摘要: The invention concerns a procedure to determine the oxygen storage capability of an emission control system with an exhaust gas sensor with discrete-level ability disposed in front of the emission control system.If in a period of time before the determination of the oxygen storage capability, the control intervention of the exhaust gas sensor is ascertained, and if this mean value is taken into consideration when calculating the fuel-delivery control phase during the determination of the oxygen storage capability of the emission control system, or if this mean value is used to correct the lambda value used to calculate the amount of oxygen stored, an improved measuring accuracy can be achieved while using a cost effective discrete level sensor. In that during the rich or lean operation of the cycle to determine the oxygen storage capability, the mean value of the control intervention is used for the calculation, pre-control errors are compensated for, as they can arise, for example, through dispersion of the injection valves or errors in the acquisition of cylinder fill. If the mean value is used to correct the lambda value, the amount of oxygen stored can be more accurately determined as a result of the measured air mass. In the procedure according to the invention, a cost effective step discrete-level sensor can be used in front of the emission control system.
