Abstract:
1. An exhaust manifold for an internal combustion engine in motor vehicles with exhaust turbocharging and an exhaust gas recirculation device for recirculating exhaust gas from the exhaust manifold to the engine inlet, wherein the exhaust manifold comprises: a header pipe with several inflow openings connected with the combustion chambers of the internal combustion engine, and outlet openings branching from the header pipe via connecting branches for the exhaust gas recirculation and the exhaust turbocharger, and a flow guide element arranged in the header pipe proximate the outlet openings, the flow guide element having three guide walls and dividing an exhaust gas flow in the header onto the outlet openings in a targeted manner, wherein the flow guide element is approximately Y-shaped in cross section with one of the guide walls oriented in a flow direction of the exhaust gas in the header pipe and two further ones of the guide walls each extending toward a respective one of the outlet openings.
