Method and apparatus for reducing harmful constituents of exhaust gas of a combustion engine |
摘要 |
<p>Process for operating a continuously reducing particle reducing device of an internal combustion engine (1) having an oxidation catalyst (6) and a particle filter (7) in an exhaust gas line (3) comprises increasing the NOx amount of the exhaust gas when the particle filter exceeds a predetermined upper charge threshold. An Independent claim is also included for a device for carrying out the process comprising a control device (14). Preferred Features: The NOx amount of the exhaust gas is reduced after falling short of a predetermined lower charge threshold. The charge state of the filter is established by measuring the exhaust gas counter pressure via a gas pressure sensor.</p> |
