20090241516 | SYSTEM AND METHOD FOR REGENERATING A CATALYTIC PARTICULATE FILTER LOCATED IN A DIESEL ENGINE EXHAUST LINE - 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. | 10-01-2009 |
20100162687 | METHOD AND DEVICE FOR THE CONTROL OF THE OPERATING STATE OF THE CATALYTIC CONVERTER OF THE EXHAUST LINE OF AN INTERNAL COMBUSTION ENGINE - A device for controlling the operating state of a catalytic converter in the exhaust line of an internal combustion engine, including a mechanism for determining the temperature upstream and downstream of the converter, a mechanism for injecting fuel in the exhaust line of the engine, a mechanism for calibrating a temperature model on a measured operating temperature of the catalytic converter, and a mechanism for calculating the integral of the difference between the measured temperature and the modeled temperature downstream of the converter. | 07-01-2010 |

20090188239 | SYSTEM AND METHOD FOR REGENERATING A CATALYTIC PARTICULATE FILTER LOCATED IN A DIESEL ENGINE EXHAUST LINE - 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 filter and supplied with fuel by a controlled pump, and a sensor for measuring the fuel feeding pressure of the injector. Further, a detection mechanism detects an open position locking of the injector based on the fuel feeding pressure of the injector. | 07-30-2009 |
