摘要： An electronic control device according to the invention is disclosed for controlling the internal combustion engine in a motor vehicle, for fault recognition with an irregular running determination unit and with an injection quantity correction unit, a defined group of cylinders being associated with a lambda probe, the injection quantity of a cylinder to be investigated of the defined group is adjusted in the direction of lean by a differential adjustment value associated with an irregular running differential value, and the injection value of at least one of the remaining cylinders, which are associated with the same lambda probe, is correspondingly adjusted in the direction of rich, so that in total a predetermined lambda value of this group of at least approximately 1 is reached. Homogeneous operation is thus ensured. The differential adjustment values may, for example, relate to the injection quantity itself, the injector stroke or the injection time. In this manner, a differential adjustment value individual to the cylinder is adjusted for each cylinder of the defined group. Correction values individual to the cylinder are then determined in that the differential adjustment values individual to the cylinder are related to one another.

摘要： An injection valve of an internal combustion engine is actuated at least once by at least one specified control value of an actuating variable for metering at least one specified minimum quantity corrected by a correction value. The correction value for the control value is adjusted according to a deviation of an expected response value of an actuating variable from an actual response value of the response variable, as a result of the actuation of the respective injection valve, that is to say by way of a reduction of the deviation between the expected response value of the response variable and the actual response value of the response variable. If the correction value undershoots a specified negative correction threshold value or overshoots a specified positive correction threshold value, a fault is detected in a component which is affecting the exhaust gas in the cylinder assigned to the respective injection valve.
