Abstract

Bei einer Brennkraftmaschine mit obenliegender Nockenwelle, die über ein an einer Stirnseite des Zylinderkurbelgehäuses angeordnetes Steuergetriebe von der Kurbelwelle angetrieben wird, ist das Steuergetriebe in einem Steuerkasten angeordnet, der aus einem aus Kunststoff bestehenden Hohlkörper besteht, welcher zum Zylinderkopf und zur Ölwanne hin offen ist und seitliche Fortsätze aufweist, die Durchbrüche in den Seitenwänden des Zylinderkiurbelgehäuses abdecken. Dadurch wird eine Gewichtsreduzierung und eine Verringerung der Schallabstrahlung erreicht.

Figure 00000001
In an internal combustion engine with an overhead camshaft, which is driven by the crankshaft via a control gear arranged on an end face of the cylinder crankcase, the control gear is arranged in a control box, which consists of a hollow body made of plastic, which is open to the cylinder head and to the oil pan and has lateral extensions which cover openings in the side walls of the cylinder crankcase. This results in a reduction in weight and a reduction in sound radiation.
