Cylinder head with integrated exhaust manifold and cooling jacket, of internal combustion engine

The invention relates to a cylinder head of an internal combustion engine, with at least an integrated exhaust manifold. The exhaust manifold comprises: a, at least two conduits that direct the exhaust gas, which are arranged substantially side by side with respect to each other and are collected at the flow connection portion upstream of the exhaust manifold outlet to the manifold line, respectively, which passes through the wall Of the terminal areas are separated from each other; and b, at least one coolant jacket disposed above and/or below at least and having an upper dividing wall and a lower dividing wall, wherein the at least one coolant jacket and the pipe are separated from each other by a common dividing wall The coolant jacket is passed through the coolant in a fixed flow direction, wherein at least one tab extends between the upper dividing wall and the lower boundary wall in the coolant jacket, which has an upstream flow in the upstream; the influent flow being separated by a flow of coolant, wh
