SYSTEM FOR RECIRCULATING ENGINE EXHAUST GAS

摘要

The present invention relates to a system for recirculating engine exhaust gas. The system for recirculating engine exhaust gas according to the present invention comprises: first and second cylinder groups (12a, 12b) consisting of cylinders selected from among the cylinders of an engine; a first manifold (21) connected to the first cylinder group (12a) so as to combine and discharge the exhaust gases discharged from the cylinders of the first cylinder group (12a); a second manifold (22) connected to the second cylinder group (12b) so as to combine and discharge the exhaust gases discharged from the cylinders of the second cylinder group (12b); a branching unit (100) connected to the first manifold (21) and the second manifold (22) so as to combine the exhaust gases discharged from the first manifold (21) and the second manifold (22); first and second exhaust lines (23, 24), one side of each of which is branched by the branching unit (100), and the other side of each of which is connected in a pair to a turbine (30) of a turbocharger so as to provide a portion of the exhaust gas to the turbine (30); and a joint recirculation line (70) branched from the branching unit (100).
