GAS EXCHANGE CHANNEL FOR AN INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a gas exchange channel (2) for an internal combustion engine. A valve seat ring (4) is arranged in the region of an orifice (3) in a combustion chamber and a flow separation edge (8) which is preferably formed by a control section is arranged on one side of the gas exchange valve (2) in the region of the orifice (3) in the combustion chamber. In order to generate high charging movements and to maintain the flow resistance as low as possible, the flow separation edge (8) is formed by the inner cover surface (5) of the valve seat ring (4).
