METHOD FOR CONTROLLING AN IONIZATION DEVICE IN AN EXHAUST GAS POST-TREATMENT DEVICE

摘要

A method for regulating an ionization device in an exhaust gas after-treatment device of an internal combustion engine, includes placing at least one cathode at a distance from an anode in the exhaust gas after-treatment device, applying a high voltage between the at least one cathode and the anode, predefining a first value for the high voltage, detecting a current generated by the high voltage between the at least one cathode and the anode and predefining a second value for the high voltage if the detected current exceeds a predefinable first current intensity for a predefinable number of times. A motor vehicle in which the method is carried out is also provided.
