Abstract (en)
[origin: WO2012150084A1] The invention relates to a device for controlling an internal combustion engine in a motor vehicle, comprising a unit for detecting uneven running (420) and a unit for correcting injection quantities (450), a group of cylinders being associated with a lambda probe. Said device is characterised in that the uneven-running detection unit (420) identifies the uneven running (LU) of a cylinder, compares this to a predefinable threshold value (110) and, if the identified uneven running (LU) exceeds said predefinable threshold value (110), the injection-quantity correction unit (450) adjusts the injection quantity of said cylinder towards a richer mixture, and adjusts the injection quantities of the remaining cylinders of the group such that, in total, a predefinable group lambda value is obtained which is preferably a lambda value of 1, and a lambda deviation is able to be determined for each individual cylinder in an adaption unit (440).
