LIGNE D'ECHAPPEMENT AVEC UN CONDUIT DE RECYCLAGE DES GAZ D'ECHAPPEMENT MUNI D'UN ECHANGEUR DE RECUPERATION DE CHALEUR.

摘要

The line (10) has a main exhaust gas circulation pipe (22) connected to exhaust gas outlets of combustion chambers of an engine (14). An exhaust gas recycling pipe (28) has a downstream recycling section (30) for channeling the gas to inlets of the chambers. A heat exchanger (32) is interposed in series between the section and an exhaust gas purification unit (26). An internal section of a communication opening between the exchanger and the purification unit is 50 percentages of an internal section of the exchanger perpendicular to a direction of flow of exhaust gas into the exchanger.
