Computer controlled exhaust particle regeneration system for a diesel automotive engine, has electrovalve to regulate EGR as a function of inlet oxygen content during filter regeneration

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.
