Definitions
- the invention relates to a valve-controlled internal combustion engine in the Preamble of claim 1 described type.
- the adjustment device to change the compression of this valve-controlled internal combustion engine comprises a controlled in a cylinder head guided sliding Sleeve with an opening arranged in the sleeve jacket over which a channel section of a gas exchange channel running in the cylinder head a duct section formed by the sleeve on the combustion chamber side stands, with a channel opening delimited by the sleeve on the combustion chamber side a lift valve is controlled.
- This known adjusting device forms in principle be closed by the globe valve Sleeve a piston, by means of its variable position a compression volume can be changed in a cylinder depending on the operating point.
- this known adjusting device is that the globe valve and the sleeve each via assigned cam disks on a common control shaft are actuated, the respective cams on the common star shaft are non-rotatably arranged in a fixed rotation angle assignment.
- DE 38 01 102 A describes a further adjustment device for changing the compression known in an internal combustion engine with a secondary piston in the cylinder head arranged sleeve with a gas exchange valve, in which the secondary piston to change the compression independently of the control of the gas exchange valve is adjustable.
- this is disadvantageous with the secondary piston or moved with the sleeve in a recess of the cylinder head Channel section, which requires a complex cylinder head design.
- the invention has for its object to be a generic internal combustion engine to design the adjustment device for changing the compression in such a way that both control devices are decoupled with a simple structure of the Cylinder head.
- its compact design makes it more electromagnetic Actuator equipped, but it is also hydraulic or hydraulic pneumatic actuator possible.
- the invention is based on a preferred example shown in the drawing described.
- a valve-controlled internal combustion engine 1 shown only in sections is with an adjusting device 2 for changing the compression in the combustion chamber 3 between the piston 4 in the cylinder 5 of the internal combustion engine 1 and a combustion chamber calotte 6 equipped in a cylinder head 7.
- the adjusting device 2 comprises a sleeve 8 guided with sliding movement in the cylinder head 7 with a in the sleeve jacket 9 arranged opening 10 through which a in the cylinder head 7 extending channel section 11 'of a gas exchange channel 11 with one of the Sleeve 8 formed combustion chamber-side channel section 11 '' is connected.
- the by the sleeve 8 limited combustion chamber side channel opening 12 by means of a Lift valve 13 controlled.
- valve lift actuating device is preferably an electromagnetic one Actuator 14.
- a hydraulic or pneumatic actuator is also conceivable.
- the sleeve 8 via a preferably eccentric controlled as a function of the operating point 15 cam disc designed to change the compression separately in the cylinder head can be pinned.
- An effective compression change is achieved in particular that several Similar lift valves 13 per combustion chamber 3, each with an adjusting device 2 are combined. Furthermore, the change in compaction can be increased by that inlet and outlet-side lift valves 13 each with an adjusting device 2 are combined.
- the respective actuator 14 can also be used as an actuating device with a variable Valve stroke can be designed, whereby adapted on the intake side depending on the operating point Valve opening cross sections for advantageous inflow control are possible.
