Exhaust circuit for use in internal combustion engine, has two upstream sections opening in respective exhaust processing devices, where output section of one device includes coupling unit connecting upstream sections to downstream section

摘要

The circuit has an upstream section (18), including an exhaust collector (26) associated to a cylinder head (14), opening in an exhaust gas processing device (30). Another upstream section (20) having an exhaust collector (28) associated to a cylinder head (16) opens in an exhaust gas processing device (32). An output section of the device (30) has a coupling unit connecting the sections (18, 20) to a downstream section (22).
