- This preassembled camshaft module or cylinder head cover module can then be mounted on the cylinder head as a whole.
- the camshafts receiving the first bearing halves are formed integrally with the cylinder head cover.
- the cylinder head cover can e.g. not be formed of plastic, but it must be made of a material that is suitable for the bearing halves for mounting the camshaft and has sufficient strength. Therefore, the cylinder head cover according to DE 201 20 912 U1 is made of a suitable metal, e.g. Aluminum, consist.
- a further disadvantage is that the integrally formed with the cylinder head cover bearing halves must be machined consuming to achieve the necessary for the storage of the camshaft dimensions, tolerances and surface quality.
- the process of pre-assembly of the camshaft module and its screw connection to the cylinder head of the internal combustion engine in the camshaft module known from DE 201 20 912 U1 is comparatively complicated. After the second bearing halves are bolted to the first, integrally formed with the cylinder head cover bearing halves, the pre-assembled in this way camshaft module must be bolted to separate attachment points and separate screws with the cylinder head.

- a cylinder head cover made of plastic.
- the camshaft is received rotatably supported in separate bearing blocks, and that these bearing blocks are connected to each other at individual attachment points with the cylinder head cover via a fastening means.
- the camshaft module is firmly connected to the abovementioned fastening points via the same aforementioned fastening means with the cylinder head of the internal combustion engine.
- the fastening means may be formed as screws. In this way, only one set of screws is needed to pre-assemble the camshaft module and then screw it firmly to the cylinder head.
- the bearing blocks can be designed as individual bearing blocks or else as so-called double bearing blocks. If they are designed as individual bearing blocks, then the individual bearing blocks can be designed so that they can be connected to one another.
- the bearing blocks may be formed as a split or as a closed (one-piece) bearing blocks.
- camshaft module preassembled in this way is then placed on the cylinder head and secured with the same fastening means, e.g. secured to the cylinder head with the same screws used to pre-assemble the camshaft module.
- one or more plug connections can be provided, by which the bearing blocks receiving the camshafts can be connected to the cylinder head cover, i. are pluggable.
- the bearing blocks together with the camshaft are first simply plugged together with the cylinder head cover and thereby held together positively, positively or force and form-fitting manner.
