A valve train of an internal combustion engine of a motor vehicle includes a rocker arm assigned to a first combustion chamber of the internal combustion engine where via the rocker arm a gas exchange valve assigned to the first combustion chamber is actuatable. An actuating device is assigned to a second combustion chamber of the internal combustion engine where via the actuating device, by supplying the actuating device with a hydraulic fluid, the second combustion chamber is switchable between a firing mode for fired operation and a braking mode for an engine braking operation of the internal combustion engine. A supply of the hydraulic fluid to the actuating device assigned to the second combustion chamber is adjustable by the rocker arm assigned to the first combustion chamber.

Valve train for an internal combustion engine of a motor vehicle, and method for operating such a valve train

In a clearance compensating device for an internal combustion engine with an internal part movably arranged within a guide duct of an external part for adjusting a clearance of an associated valve of the internal combustion engine, a pressure chamber, and a storage chamber which is hydraulically connected to the pressure chamber for receiving hydraulic fluid are associated with the interior part. Between the two chambers a one-way valve is disposed for applying an actuating force to the interior part relative to the external part. A feeding device is hydraulically connected to a blocking chamber for supplying a hydraulic fluid to the blocking chamber in order to exert a blocking force to the internal part acting in a direction opposite the actuating force under the control of a timing device the blocking force being modified depending on a cycle of the timing devices.

In an arrangement and method for mounting a camshaft onto a cylinder head of an internal combustion engine by camshaft bearings disposed on the cylinder head of the engine camshaft bearing by support seats which are formed integrally with the cylinder head and bearing caps which are formed integrally with a cylinder head cover mounted onto the cylinder head, at least one of the bearings is an assembly bearing with a separate assembly bearing cap that has a bearing opening of a diameter greater than that of the camshaft so that the camshaft when placed onto the bearing seats is not fully moved into the bearing seat openings but is fully engaged with the bearing seats only when the cylinder head cover is mounted onto the cylinder head whereby the camshaft in the assembly bearing is moved out of contact with the assembly bearing cap.
