Intake manifold for an internal combustion engine having a cylinder head

Abstract

An intake manifold for an internal combustion engine having a cylinder head is disclosed. The intake manifold includes at least one intake pipe with an intake flange for leak-free attachment of the manifold to the cylinder head by way of a sealing element. A bypass line is provided for feeding a secondary gas into the intake opening of the internal combustion engine. The secondary gas is fed into the bypass line through a connection, preferably a hose connection. The bypass line is formed by a groove in the intake flange which is open in the direction of the cylinder head and delimited on one side by the intake flange and on the other side by a sealing element. The connection is connected to one end of the groove, and the intake opening is connected to the other end of the groove.

Dependencies are inferred from the claim text.
