摘要： Disclosed is a particulate filter regenerating system which comprises a fuel injection device (7) adapted to inject fuel into a combustion chamber of an engine body (1), and an exhaust gas temperature-adjusting device (33) adapted, when a PM deposit amount which is an amount of particulate matter (PM) deposited in a DPF (particulate filter) 13 provided in an exhaust passage of an engine, reaches a predetermined value X, to cause the fuel injection device (7) to perform a post-injection for injecting fuel into the combustion chamber during an expansion stroke of the engine, so as to execute a filter regeneration process of raising a temperature of exhaust gas flowing into the DPF 13 to burn the deposited PM. The exhaust gas temperature-adjusting device (33) is operable to cause the fuel injection device (7) to stop performing the post-injection in a stage where a PM burning amount which is an amount of PM burned through the filter regeneration process, is less than an initial PM deposit amount which is the PM deposit amount X at a timing of initiation of the filter regeneration process, by a predetermined amount. The particulate filter regenerating system of the present invention can adequately burn and remove PM deposited in a particulate filter, by means of a post-injection of fuel, while effectively suppressing a fuel consumption due to the post-injection.

摘要： Disclosed is a particulate filter, which is adapted to be disposed in an exhaust passage of an engine to trap particulate matter contained in exhaust gas discharged from the engine. The particulate filter comprises a filter body having a porous partition wall which defines a plurality of exhaust gas channels allowing the exhaust gas to pass therethrough, and a catalyst layer formed on a surface of the porous partition wall. The catalyst layer includes a Zr-based composite oxide which contains zirconium (Zr), and a rare-earth metal except cerium, wherein a content ratio of an oxide of the non-cerium rare-earth metal to a total amount of ZrO2 and the oxide of the non-cerium rare-earth metal in the Zr-based composite oxide is set in the range of greater than 33 mol % to less than 40 mol %. The particulate filter of the present invention can achieve a higher PM burning rate to burn PM within a shorter period of time. In addition, the higher PM burning rate makes it possible to provide enhanced fuel economy performance in an engine designed to perform a post-injection control.
