    摘要: A method and device for monitoring errors in an exhaust gas recirculation line, including supplying an engine with fresh air via a supply duct using a compressor, discharging exhaust gas via an exhaust duct using a gas turbine, a subflow of the gas being supplied from a low-pressure area of the exhaust duct downstream from the turbine, via the recirculation line, to an intake air low-pressure area of the supply duct upstream from the compressor, an exhaust gas mass flow of the subflow in the recirculation line is set via a valve, a fresh air mass flow being set by a fresh air throttle, or via an exhaust flap in the exhaust duct. Where the fresh air throttle or the exhaust flap is opened when the recirculation line is free of errors, an error in the recirculation line is deduced if the throttle or flap is at least partially closed.
