Abstract: The invention relates to an arrangement for sealing a stationary timing housing cover at the end face of an internal-combustion engine housing comprising cylinder head and crankcase. The timing housing cover is composed of a cylinder head side and a crankcase side cover part, between which an elastomer profile seal element is retained under compressive stress. The seal element exhibits a sealing lug oriented at right angles to the separating line to seal the end face contact surface of the internal-combustion engine housing in the plane of the separating line running between cylinder head and crankcase in the region of the adjacent edges of cylinder head, crankcase, cylinder head gasket located between the two latter, and the cover parts. The cylinder head gasket is provided with a flowable sealing medium applied bead-fashion on its end edge which faces the timing housing cover.

Abstract: A ventilating system on an internal-combustion engine is described that has balancer shafts for the balancing of mass of the second degree, the balancer shafts are driven by a crankshaft via a toothed belt in a clutch housing into which fresh air is blown via an inlet opening for cooling purposes. For an improved direct cooling of the toothed belt, at least one air guiding duct is connected to the inlet opening. This air guiding duct is formed by ribs and has at least one outlet opening in the direct area of the toothed belt from which air blows out in a targeted manner onto the toothed belt.

Abstract: A sealing arrangement between a pipe flange and a screw-on surface for the pipe flange, in which an abutment surface is provided at either the screw-on surface or the pipe flange which extends perpendicularly to the abutment surface of the flat seal in the direction toward the oppositely disposed abutment surface of the pipe flange or screw-on surface, and which is at least approximately tangent to the outer contour of the flat seal at a circumferential place outside of the point of intersection of a line of symmetry with the outer contour of the flat seal; rejection lugs are provided at the outer contour of the flat seal at those places which are disposed opposite the contact places between the abutment surface and the outer contour of the flat seal in relation to the line or lines of symmetry.
