Abstract

Abstract Translated from German Die Zylinderkopfhaube (9) und die Saugrohranlage bilden eine Baueinheit. Die Baueinheit ist unter Vermittlung von Schrauben und federnden Elementen an einem Zylinderkopf (2) der Brennkraftmaschine gehalten, wodurch die Geräuschab­strahlung der Brennkraftmaschine verringert wird. Außerdem ist zur Vermei­dung von Füllungsverlusten eine Wand der Zylinderkopfhaube, die Bestandteil der Saugrohranlage (13) ist, mittels einer Abdeckung gegen heißes Spritzöl aus dem Zylinderkopf (2) abgeschottet. The cylinder head cover (9) and the intake manifold form a structural unit. The assembly is held on a cylinder head (2) of the internal combustion engine by means of screws and resilient elements, as a result of which the noise emission from the internal combustion engine is reduced. In addition, to avoid filling losses, a wall of the cylinder head cover, which is part of the intake manifold system (13), is sealed off from the cylinder head (2) by means of a cover against hot spray oil.
