Abstract

The system has an exhaust gas recuperating circuit (4) emerging from an air intake circuit (2) of an engine (10). A blow-by gas recuperating circuit (3) is connected in the exhaust gas recuperating circuit in downstream of a heat exchanger (41). The heat exchanger is placed on the exhaust gas recuperating circuit. An upstream pipe (42) of the recuperating circuit (4) and a settled gas transfer pipe (32) of the recuperating circuit (3) emerge from a common inlet case of the heat exchanger.
