<p><P>PROBLEM TO BE SOLVED: To provide a failure diagnosis device for a particulate charger capable of accurately performing failure diagnosis of the particulate charger for charging the particulate in exhaust gas. <P>SOLUTION: In the particulate charger 4 for charging the particulate in the exhaust gas G, the failure diagnosis is performed by a control unit 15. In the failure diagnosis, the particulate charger is determined whether it fails or not based on the difference or ratio between the discharged amount of particulate detected by a particulate discharge amount detection device when the particulate charger is operated and the discharged amount of particulate detected by the particulate discharge amount detection device when the particulate charger is not operated by using the particulate discharge amount detection device 20 installed in an exhaust passage 3 on the downstream side more than the particulate charger and detecting the discharged amount of particulate. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
