Integrated exhaust gas management device

The present invention relates to a device for managing gases suitable for being installed at the outlet of a particle filter or a catalytic converter. This device is characterized by a very compact configuration combining at least the heat exchanger for an EGR ( Exhaust Gas Recirculation ) system, particularly suitable for a low-pressure system, and an exhaust gas outlet pipe with a special configuration that is part of the exhaust line. The exhaust outlet incorporates a valve that allows using the heat exchanger of the EGR system as a heat recovery unit.
