An internal combustion engine has an oil circuit for supplying oil to powertrain components and cylinder head components of the internal combustion engine. At least one oil pump and one oil filter module are incorporated into the oil circuit. The oil circuit branches into a powertrain oil gallery and a cylinder head oil gallery in the oil filter module or downstream of the oil filter module in a flow direction. The oil circuit is designed so that a lower oil pressure prevails in the powertrain oil gallery than in the cylinder head oil gallery.

The invention relates to a vacuum cleaner comprising a lower housing part, on which wheels are mounted for moving the vacuum cleaner along a floor surface, and which forms a dirt collection container with a suction inlet to which a suction hose is connectable, and an upper housing part which is mountable on the lower housing part and accommodates an electrically drivable suction unit, and an electric supply cable for connecting the suction unit to an electrical voltage source. In order to develop the vacuum cleaner so that it is easier to handle, and the supply cable and the suction hose can be held in a simple way for storage on the vacuum cleaner and removed from the vacuum cleaner for use, it is proposed, in accordance with the invention, that the vacuum cleaner have a cable receptacle for storing the supply cable and a hose mount for storing the suction hose, the cable receptacle surrounding the upper housing part on the outside in the circumferential direction, and the hose mount being arranged below the cable receptacle.

A system for supporting the torque of an internal-combustion engine has a support arranged transversely in the vehicle. This support has a strut as well as a support arm. These two support parts are connected with one another by way of an elastic bearing, the strut being fastened on a camshaft housing and the support arm being fastened on the side member of the vehicle. The elastic bearing is connected with the vehicle body structure, for example, on a spring strut dome, by way of a console.
