摘要： A method for controlling an internal combustion engine of a motor vehicle. The method includes the use of an electronic control device for controlling the internal combustion engine in a motor vehicle, an irregular running determination unit for fault recognition, an injection quantity correction unit, a lambda probe associated with a defined group of cylinders, 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.

摘要： A method for controlling an internal combustion engine of a motor vehicle with an injection quantity correction unit is disclosed. The method includes the use of an electronic control device 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. The correction values individual to the cylinder are compared for fault recognition with at least one threshold value.

摘要： In a method and apparatus for detecting exhaust-gas-impairing and catalyst-damaging misfires in an internal-combustion engine, having a lambda probe arranged behind a catalyst, combustion misfires in at least one cylinder of the internal-combustion engine are detected by analysis of rotational engine speeds (or by another technique for detection of the erratic running of the engine). To improve the diagnosis of exhaust-gas-impairing of catalyst-damaging misfires a two stage method is provided to determine the lambda probe voltage, to assign it to the detected combustion misfires and to determine the respective type of misfire as a function of the probe voltage.
