Method for operating internal combustion engine, involves executing variation of ignition of cylinder of internal combustion engine during operation of internal combustion engine without operating lambda probe

摘要

The method involves executing a variation of ignition of a cylinder (2) of an internal combustion engine (1) during the operation of the internal combustion engine without operating a lambda probe (8). The torque contribution is prepared by the change results in the variation of the ignition of the cylinder.
