Abstract

A method for operating an internal combustion engine that includes at least two cylinders, includes operating the internal combustion engine in a first operating mode in partial engine operation, in which at least one of the cylinders is not fired, monitoring the internal combustion engine during the partial engine operation for potentially torque-increasing errors, and switching over from the partial engine operation into a full engine operation in which all of the cylinders are fired when a potentially torque-increasing error is detected.
