Abstract

A device for EGR recirculation in a multi-cylinder turbocharged combustion engine (1) whereby a valve-controlled EGR line (4) runs between the engine's exhaust side (2) and inlet side (3) and a turbine unit (6, 7) is accommodated in a turbine housing (6) into which exhaust gas manifolds lead from the exhaust ducts of the cylinders. The turbine housing (6) incorporates an EGR duct section (10) which is arranged to draw from an exhaust gas flow heading for the turbine (7) and in which an EGR valve (11, 12) is arranged.
