Abstract: In an internal combustion engine including a cylinder head and at least one camshaft and accessory units comprising pumps mounted on the front end of the engine on which also drive means for the camshaft of camshafts are disposed, the accessory units are operatively coupled to the drive means for the camshafts or camshafts so as to be driven thereby.

Abstract: A cylinder head cover for a direct-injecting internal-combustion engine has an injection nozzle holder arranged in the cylinder head between charge cycle valves and a clamping shoe for fixing the position of the injection nozzle holder in a receiving bore in the cylinder head. The cylinder head cover is constructed to be pulled in in the area of the injection nozzle holder and has a passage for the injection nozzle holder. The pulled-in cylinder head cover in the area of the injection nozzle holder is pulled down to the cylinder head. Starting from that area, a drainage-groove-type indentation leads to the inlet side of the internal-combustion engine.

Abstract: A cylinder head for a multi-cylinder internal combustion engine with a cylinder head block which bounds a cooling water space, is closed at the top by a cylinder head cover plate and has tubular chambers extending in the direction of the cylinder axis to accommodate a spark plug, an injection nozzle or an injection nozzle with precombustion chamber. A camshaft space is located above the cover plate with devices for valve control, and a bearing pedestal to accommodate at least one camshaft is provided in the camshaft space. The bearing locations for the camshaft are covered by bearing covers. In order to reduce the manufacturing requirements and, furthermore, to minimize the noise radiation caused by the cylinder head side walls, a split plane formed between the cylinder head block and the bearing pedestal extends at the level of the upper chamber edge.

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.
