Cylinder head cover module with integrated valve train
View Patent ↗An internal combustion engine includes a cylinder block, a cylinder head and a cylinder head cover module attached to the cylinder head. The cylinder head cover module includes passageways and a plurality of receiving features for valve train components. A housing may be integrally formed with the cylinder head cover module. The cylinder head cover module may include components of a non-integrated valve control system and may be used in either an inline or a V-shaped engine.
1. A cylinder head cover module, comprising:
a cover unit integrally formed with a valve train housing, the combined cover unit and valve train housing adapted to be attached to a cylinder head as a cylinder head cover module, the cylinder head cover module having a plurality of receiving features for valve train components and also including at least one each of a hydraulic cylinder, a solenoid, a pump, and a cam shaft,
wherein the cylinder head cover module has a vertical profile measured from a mounting plane of the cylinder head to a top of the cover unit that is shorter than 107 cm.
2. The cylinder head cover module of claim 1 , wherein the cylinder head cover module is adapted to be sealed to the cylinder head.
3. The cylinder head cover module of claim 1 , wherein the valve train housing includes a plurality of passageways for hydraulically-actuated valves.
4. A vehicle engine, comprising:
one or more cylinder blocks that each include a plurality of cylinders;
a cylinder head mounted onto each cylinder block and enclosing the plurality of cylinders; and
a cylinder head cover module attached to each of the cylinder heads, the cylinder head cover module including a cover unit integrally formed with a valve train housing and having a plurality of receiving features for valve train components and also including a hydraulic cylinder, a solenoid, a pump and a cam shaft.
5. The vehicle engine of claim 4 , wherein each cylinder head cover module is sealed to a corresponding cylinder head.
6. The vehicle engine of claim 4 , wherein the cylinder head cover module houses components of a non-integrated valve control system.
7. The vehicle engine of claim 6 , wherein the vehicle engine is a V-shaped engine.
8. The vehicle engine of claim 6 , wherein the vehicle engine is an inline engine.
9. The vehicle engine of claim 4 , wherein the valve train housing includes a plurality of passageways for hydraulically-actuated valves.
10. The vehicle engine of claim 4 , wherein the corresponding non-integrally-formed valve train housing and cylinder head cover has a vertical profile of 107 cm.
