CHECKING AN EXHAUST GAS FLAP |
摘要 |
The invention relates to a method for checking a valve on an exhaust gas turbocharger of an internal combustion engine, wherein an exhaust gas flow exits the internal combustion engine, a first portion of said flow flowing through a turbine of the exhaust gas turbocharger into an exhaust gas system and a second portion flowing through the valve into the exhaust gas system, wherein said method comprises the steps of varying a fuel-to-air ratio in a fresh gas supplied to the internal combustion engine, determining a residual oxygen content in the exhaust gas system, and determining that the valve is defective if a variation of the residual oxygen content occurs in a manner different than a predetermined manner of the variation of the fuel-to-air ratio in the fresh gas. A device for checking the valve can be integrated into an integrated engine control unit of the internal combustion engine. |
