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

摘要

A system for regenerating a catalytic particulate filter located in a diesel engine exhaust line, including an electronic control unit, a controlled fuel injector arranged upstream of the catalytic particulate filer and supplied with fuel by a controlled pump, and a sensor for measuring the fuel supply pressure of the injector. The system further detects a defect in the activating state of the pump based on the fuel supply pressure of the injector.
