Abstract

In an internal combustion engine comprising a cylinder-head with at least one combustion chamber in the cylinder head and the cylinder head has at least one intake passage and one exhaust passage, and an external exhaust gas recirculation line which branches off from the exhaust passage and opens at least into one of the intake passages, a pivotable flap is arranged between the exhaust gas recirculation passage and the associated intake passage in the region where the exhaust gas recirculation line is connected to the intake passage, the flap opening or closing a connection between the intake passage and the exhaust gas recirculation passage as a function of the pivoting position adjustment of the flap.
