Abstract (en)
[origin: WO0102711A1] The invention relates to a method of monitoring an internal combustion engine that is operated with an excess of air. If an excessive torque (TQI) is detected during the operation of the internal combustion engine in the stratified charge mode lambda >>1 or with a homogeneous air-fuel mixture lambda >1, the engine immediately switches to the homogeneous operation state lambda =1. If an excessive torque (TQI) is detected for this mode of operation, too, emergency operation modes are activated.
