Abstract

An intake system which includes an intake distributor as well as intake pipe sockets leading to inlet ports in cylinder heads of an internal-combustion engine is held on the internal-combustion engine by means of first and second decoupling elements. For the mounting of the intake distributor, a plurality of tension devices are required which tension decoupling elements supported on a flange facing of the cylinder head. The forces which are transmitted in this case by the tension devices to the intake distributor may also be supported on the cylinder head by way of additional decoupling elements which are under compression due to the tension devices.
