METHOD FOR REGENERATING PARTICULATE FILTER

A particulate filter can be regenerated more efficiently and in shorter time than before. The method is directed to forced regeneration of a catalytic regenerative particulate filter (13), an oxidation catalyst (14) being arranged in front of the particulate filter (13) incorporated in the exhaust p...

Zusammenfassung:	A particulate filter can be regenerated more efficiently and in shorter time than before. The method is directed to forced regeneration of a catalytic regenerative particulate filter (13), an oxidation catalyst (14) being arranged in front of the particulate filter (13) incorporated in the exhaust pipe (11). When the exhaust temperature measured between the oxidation catalyst (14) and the filter (13) is lower than a first preset temperature and is equal or more than a second preset temperature lower than the first preset temperature, post injection is added at non-ignition timing following the main injection of the fuel near the compression upper dead center to conduct fuel addition. When the exhaust temperature exceeds the first preset temperature, the post injection is stopped and fuel is directly injected into the exhaust pipe (11) upstream of the oxidation catalyst (14) to conduct the fuel addition.
