SYSTEM AND METHOD FOR REGENERATING A CATALYTIC PARTICULATE FILTER LOCATED IN A DIESEL ENGINE EXHAUST LINE

摘要

The invention concerns a system for regenerating a catalytic particulate filter (3) located in a diesel engine exhaust line (1), comprising an electronic control unit (11), a controlled fuel injector (6) arranged upstream of the catalytic particulate filer (3) and supplied with fuel by a controlled pump (9), as well as a sensor (10) for measuring the fuel supply pressure (P) of said injector (6). The system comprises means for detecting (5) a defect in the activating state of the pump (9) based on the fuel supply pressure of said injector (6).
