Definitions
- the invention relates to a preamble of claim 1
- Valve control for internal combustion engines with one equipped with gas springs electro-magnetic actuator in which one with a gas exchange valve in drive connection standing anchor between a closing magnet and an opening magnet is arranged to oscillate against restoring forces of the gas springs, the gas springs separated from each other by means of the armature from a chargeable Store a gas metered via controllable valves and from the gas springs Gas is drained via controllable drain valves.
- the invention is based, for a generic valve control the task to show a gas spring system with lower sealing losses.
- the advantage of the invention can be seen in the fact that the same, for air as a medium used sealing gap when using a medium with the air molecules in their Molecules significantly exceed size, the flow or sealing losses are significantly reduced.
- Carbon dioxide is proposed as an advantageously suitable medium for this purpose carbon dioxide generated in the internal combustion engine is preferably used for this is.
- carbon dioxide is proposed to be on the exhaust side
- Carbon dioxide of the internal combustion engine via a cleaning and / or cooling device is supplied to the memory and that the metering valves assigned to the gas springs and drain valves controlled over load ranges of the internal combustion engine serve to adjust adjusted spring characteristics.
- the invention is based on an example shown schematically in the drawing described a valve control.
- a valve controller 1 for an internal combustion engine includes one electro-magnetic actuator 2 with gas springs 3, 4, one with a gas exchange valve 5 armature 6 in drive connection between a closing magnet 7 and an opening magnet 8 oscillating against restoring forces of the gas springs 3, 4 is arranged.
- the gas springs 3 and 4 is from a rechargeable memory 9 via lines 9 'and 9 "metered a gas via controllable valves 10, with gas springs 3 and 4 gas is triggered via controllable drain valves 11.
- the invention suggest that the armature 6 as one in a cylinder 12 of the actuator 2 separating piston 13 arranged so as to be slidably movable between the two gas springs 3 and 4 is formed, being a medium with the size for the gas springs 3 and 4 of molecules exceeding air molecules is used.
- carbon dioxide (CO 2 ) is preferably used as the medium. This gives the advantage of using carbon dioxide produced during combustion in an internal combustion engine.
- the controlled inflow is made so that the metering valves 10 and drain valves assigned to the gas springs 3 and 4 11 controlled by the load ranges of the internal combustion engine adapted to the setting Spring characteristics of the gas springs 3 and 4 are used.
