In a method and a device for operating an internal combustion engine, with at least one cylinder (Z-Z) having a combustion chamber (), fuel is injected into the cylinder and a logic value (LV_FCUT) is set, in particular for stopping the injection of fuel into the cylinder, The method furthermore has the following steps: depending on a course of the highly time-resolved measurement signal of a rotational speed (N_FAST) of the internal combustion engine, a local maximum value (N_FAST_MAX) of the rotational speed is determined, a rotational speed difference (N_FAST_DIF) between the local maximum value (N_FAST_MAX) and a current measured value (N_FAST_MES) of the rotational speed is determined, and, depending on the determined rotational speed difference (N_FAST_DIF), the logic value (LV_FCUT) is set.

Method and device for operating an internal combustion engine

In a method for determining, whether a crankshaft of a combustion engine rotating forward after a reverse rotation is oscillating or continues the forward movement, when noticing a reverse rotation of the crankshaft, the covered rotational angle during a reverse rotation is detected, an actual threshold is computed by adding the covered rotational angle and a predetermined safety distance. The rotational angle of the crankshaft rotating immediately forward after a reverse rotation is compared to the actual threshold.
