Definitions
- the invention relates to a method for switching off an internal combustion engine electromagnetically operated gas exchange valves.
- the anchor has an anchor plunger that is at least partially is in direct contact with a valve tappet and therefore also the valve moved back and forth between an open and a closed position.
- Embodiments are known in which between the anchor plunger and there is a rigid connection to the valve lifter.
- the present invention is directed however, relate to embodiments in which there is no rigid connection between Armature and valve lifters are present.
- valve and Anchor tappet there is between valve and Anchor tappet a so-called valve lash adjuster, with which the distance of the two aforementioned parts can be adjusted to each other.
- valve plate is moved from the armature into an open position of the armature in its open position spent.
- the anchor tappet must always be on the valve tappet seated.
- the valve disc In the other end position, however, in which the anchor on one So-called normally open electromagnet is present, the valve disc is in its closed position on the cylinder head, and is in this state with the invention Embodiments a distance between the valve lifter and the armature lifter. Can now be released by controlling the electromagnets accordingly the armature from its end position corresponding to the open position of the opening electromagnet off, it reaches its other end position on its way to a position at which the armature tappet comes to rest on the valve tappet.
- the object of the present invention is the known method mentioned at the outset to develop in such a way that even when the engine is switched off, if possible wear and noise-free operation can be guaranteed.
- the deactivation can preferably take place in a controlled manner, i. H. it can be a regulated one Braking the armature in the direction of its rest position can be brought about. This can be achieved, for example, by further energizing the opening electromagnets. With such a controlled or regulated decay process be avoided that the electromagnetically operated valve again in a Position in which there is a distance between the armature and the valve tappet, which in turn can lead to the disadvantages mentioned above.
- the electromagnetically operated gas exchange valve shown in Figures 1 and 2 is built up essentially in a known manner.
- an actuator 10 provided with two spaced poles 12 and 14, in the grooves of each an electromagnetic coil is embedded.
- an armature 16 is arranged by alternating energization of the two Coils can be moved back and forth.
- the anchor has an anchor shaft 34, which - in the present figures - protrudes downwards.
- the actuator 10 is seated on a cylinder head 22, of which, however, only a section is shown.
- the cylinder head 22 has a recess, at the end opposite the actuator 10, a valve with a valve lifter 28 is mounted to slide back and forth.
- a valve plate 30 is arranged, against which one is shown only schematically Spring 20 is supported.
- the other end of the spring 20 is supported against one another spring seat 24, which is arranged on the cylinder head 22.
- the spring 20 biases the valve 26 to its closed position.
- a spring plate 32 is also arranged at the lower end of the armature tappet 34, against which a second valve spring 18 is supported.
- the valve spring 18 is supported their other end against the housing of the actuator 10 and acts on the Anchor in its open position.
- the armature 16 is shown by the alternating loading of the Coils reciprocated, whereby the gas exchange valve 26 between its open and closed position is moved back and forth. 1 shows the closed position of the valve and the upper end position of the armature 16 and 2 shows the open position of the valve 26 and the other end position of the armature 16. In its closed position, the valve plate of valve 26 is on the cylinder head and the anchor 16 comes to rest on the upper yoke 12.
- valve tappet 28 There is between the valve tappet 28 and the armature tappet 34 a distance 36 upper coil deactivated and the lower coil activated, so the anchor - too using the energy stored in the spring 18 - in its other end position moves, whereby the anchor plunger 34 after the distance 36 hits the valve lifter and urges the valve into its open position.
- measures are provided so that the Armature plunger 34 after the armature 16 has been detached from the upper yoke 12, if possible hits the anchor plunger 28 gently.
- the upper coil briefly energized again, resulting in a braking pulse and thus a slower one Detachment and "flying away" of the anchor leads, reducing the speed of the armature when placing the armature tappet 34 on the valve tappet 28 low can be held.
- the lower electromagnet is activated so that the valve 26 in its in Fig. 2 shown open position can be spent.
- the problem is solved that even after the parking the internal combustion engine as little noise and wear as possible of the armature tappet can be reached on the valve tappet 28.
- To this Purpose is in an internal combustion engine with several electromagnetically actuated Gas exchange valves checked which anchor is essentially in its Open position. With this anchor, the measure then becomes gentle Placing the armature tappet 34 on the valve tappet 28 is still carried out and in addition the anchor was still operated for this period. Only then is the actuator 10 disabled.
- a controlled one Stopping the armature brought about by the opening magnet 12 even after the Placing the armature tappet 34 on the valve tappet 28 still slightly energized becomes. As a result, a restrained moment continues to come to anchor 16 to effect, so that this slower and without further reverberation in its Rest position moves.
- the present invention thus also when the internal combustion engine is switched off ensures a low-noise and low-wear mode of operation.
