Regeneration system for an exhaust gas particulate filter of a diesel engine for a vehicle

The regeneration circuit for a motor vehicle exhaust gas filter has a control circuit (17) for the engine management system, to trigger a filter regeneration phase and to trigger a fuel injection phase for the multiple engine injectors. The control circuit closes the exhaust gas recycling circuit when the filter regeneration phase is in operation to allow control of the composition of the gas entering the particulate filter (17) as a function of engine isocouple. The recycling circuit can be opened and closed by a solenoid valve (4).
