Method for operating Otto internal-combustion engine, involves injecting fuel into combustion chamber of cylinder directly or indirectly, where combustion mixture is ignited in combustion chamber by ignition system

摘要

The method involves injecting a fuel into a combustion chamber of a cylinder directly or indirectly. The combustion mixture is ignited in a combustion chamber by an ignition system to a given ignition time point. An electrical measured variable (U1,U2,U3) or correcting variable of a Corona ignition system are evaluated for diagnosing the combustion, where combustion parameters are affected by combustion.
