Abstract: A cylinder head for a valve-controlled internal combustion engine with a cylinder head housing, in which there are bearing blocks for the inlet or outlet camshaft. At least one camshaft has a camshaft adjuster, by way of which the position of the drive wheel of the camshaft can be changed relative to the axis of rotation of the camshaft. At least the bearing block, which is provided next to the camshaft adjuster and is intended for the camshaft, exhibits a segment, whose width is reduced owing to a recess for the screw connection of the cylinder head housing. The bearing site, arranged next to the camshaft adjuster, provides a bearing sleeve for the camshaft, in such a manner that the segment of the bearing block that is provided with a reduced bearing block width is expanded to the actual bearing block width. The sleeve exhibits openings to supply oil for the camshaft adjuster.

Abstract: A chain drive is used for driving camshafts, secondary shafts or the like, from a crankshaft, in an internal combustion engine. A tensioner blade and a sliding blade rest against the loose end and against the load end of a chain of the chain drive. For compensating component tolerances, the sliding blade and the tensioner blade are each disposed in an articulated manner at a proximal end via a bolt. An adjusting device is applied to a distal end of each of the sliding blade and the tensioner blade, respectively.

Abstract: A cylinder head arrangement of an internal-combustion engine has a three-part housing which comprises a basic housing fitted onto a cylinder block, a bucket tappet housing inserted in the basic housing, and a fitted-on cylinder head cover. The bucket tappet housing is constructed in one piece. The guiding and bearing of engine camshafts takes place in divisible bearing brackets whose upper parts are integrated in the cylinder head cover and whose lower parts are constructed in the basic housing. As a result, a construction of the individual elements is obtained which is easy to manufacture and is largely free of undercuts, the individual elements having a high overall stiffness in the mounted condition and being easy to mount.

Abstract: An internal combustion engine includes a crankcase with a crankshaft which drives at one end face of the crankcase, auxiliary aggregates--oil pump--and endless elements. The oil pump and the endless elements are covered off by means of a covering which consists of a sheet metal part including two thin-walled layers and is constructed pot-shaped in cross section. This light-weight covering which is simple in construction is secured at the end wall of the crankcase by means of an edge flange and by means of bolts.

Abstract: A venting arrangement with integrated oil separator is arranged at a crankcase of an internal combustionengine with preferably V-shaped cylinder rows and includes a housing with the oil separator. The housing is formed for reasons of structural simplification by an upper part and by a lower part which have both pot-shaped configurationand upright, mutually overlapping boundary walls and form a unit. The boundary walls of the upper part are supported at the crankcase by means of flanges which assures a simple installation of the venting arrangement.

Abstract: An actuating arrangement connected with throttle valves of suction pipes of an internal combustion engine which are to be actuated synchronously. The throttle valves include bearing shafts and cooperate by way of levers with a linkage of the actuating arrangement. For the compensation of tolerances of the actuating arrangement, especially angular tolerances of the throttle valves, yielding members are provided between the linkage and the bearing shafts, and a device stresses the throttle valves into the closed end positions.
