摘要:
A method for diagnosing a particle filter arranged in the waste gas line of an internal combustion engine has the steps of: executing at least one fuel injection, measuring HC emission in the waste gas line in the direction of flow of the waste gas behind the particle filter, and diagnosing a defect of the particle filter based on the measured HC emission.
