System for the regeneration of a diesel engine exhaust gas particulate filter

摘要

The unit (4) for recycling the exhaust gases to be input into the engine includes an electrovalve whose functioning is controlled by a control unit (17) as a function of information delivered by the lambda probe (24) disposed in the motor inlet, for regulating the recycling of the exhaust gases as a function of the oxygen content of engine inlet air, during the exhaust particulate filter regeneration phase.
