Abstract
An exhaust manifold for an internal combustion engine with exhaust turbocharging and an exhaust gas recirculation device, includes a header pipe with several inflow openings connected with the combustion chambers of the internal combustion engine via connecting pieces, and outlet openings branching from the header pipe via connecting branches for the exhaust gas recirculation and the exhaust turbocharger. To achieve a high exhaust gas recirculation. rate and an effective pressurization of the exhaust turbocharger with exhaust gas, at least one flow guide element is arranged in the header pipe close to the outlet openings which divides the exhaust gas flow onto the two outlet openings in a targeted manner.
