Abstract
A fastening device, fixing an exhaust manifold () on a cylinder head () of an internal combustion engine, has a contact surface () supported relative to a cylinder head contact surface (). A fastening edge area () has a wedge fastening flange area () with a fastening element support surface () inclined in relation to the contact surface () that has a wedge angle (W). A fastening element () is pressed against the fastening element support surface () with a fastening flange support surface () with a fastening bolt unit () supported in relation to the cylinder head (). The wedge angle (W) and a coefficient of static friction (μ) of the frictional interaction of the fastening element () in relation to the exhaust manifold () is defined by: 0<W<2 tan(μ), in which Wis the wedge angle, and μ if the coefficient of static friction.
