摘要： A device for error monitoring in an internal combustion engine system is provided. The internal combustion engine is supplied with air at a volumetric efficiency indicating the ratio of a real volume flow of air in the internal combustion engine to an ideal, theoretically possible, volume flow of air in the internal combustion engine. The device for error monitoring is configured to determine an error in the engine system when a difference between a measured volumetric efficiency and an estimated volumetric efficiency exceeds a predetermined absolute value.
