Abstract

The circuit has an exhaust line (6) provided with a particle filter (10), and a gas recirculation channel (14) connected to the line at one of its end in downstream of the filter and to an engine inlet circuit (4) at another end. A heat exchanger (17) cools gas in the channel. A tube (18) playing role of bypass is arranged at downstream of the exchanger for returning the channel to the exhaust line. Control units control flow of gas admitted in the channel in a selective manner, and orientation units orient the gas towards an inlet circuit or towards the tube.
