摘要： A method and a device are proposed for controlling and/or diagnosing a control system influencing a mass flow. In this context, a correction value is calculated, which corrects the controlling, or is evaluated for diagnostic purposes. The correction value, in this context, is derived from the line resistance of the mass flow line.

摘要： The goal is to reliably diagnose and compensate for a change in the gas flow passing through an exhaust gas recirculation line. For this purpose, according to a first method, the mass flow passing through the exhaust gas recirculation line is derived as a function of the position and the flow characteristic of the exhaust gas recirculation valve, and, according to a second method, the mass flow is derived from the fresh-air mass flow in the induction pipe and from the induction pipe pressure. Then the difference is determined between the mass flows as ascertained in accordance with the two methods, and from the difference one or plurality of correcting quantities is generated for the mass flow that is derived as a function of the valve position and of the flow characteristic.

摘要： An internal combustion engine, especially for a motor vehicle, is described, which is provided with a storage catalytic converter which can be loaded with and unloaded of nitrogen oxides. Several states of deterioration (points 13) of the storage catalytic converter can be determined by the control apparatus. A sulphur content of the fuel used can be determined by the control apparatus from sequential states of deterioration (points 13).
