Definitions
- the invention relates to a method and a device for opening and closing a valve of an internal combustion engine.
- the camshaft-controlled valve actuation, the electromagnetic and the hydraulic valve control are known.
- the invention is based in principle on electromagnetic valve control (EMVS). But you can also in connection with others such.
- EMVS electromagnetic valve control
- B. use hydraulic or pneumatic valve controls.
- the EMVS was built as a one-mass transducer.
- An armature can swing back and forth between two solenoids.
- the armature is connected to the valve.
- the armature When de-energized, the armature is located approximately in the middle between the two solenoids. Due to the large gap distances in the rest position and the associated poor efficiency, a disproportionate amount of energy is required during acceleration, which in itself questions the feasibility of EMVS in series applications.
- Another disadvantage is that - in order to reliably prevent contact of the valve with the piston - valve niches must be incorporated in the piston or that the wall of the combustion chamber in the cylinder head must be set back. In terms of combustion technology, these measures have a negative impact on the combustion chamber.
- the invention is therefore concerned with the problem of reducing the use of energy in the case of electromagnetic or hydraulic valve controls and avoiding a negative influence on the combustion process by valve niches or recessed combustion chamber walls on the cylinder head.
- the basic idea of the invention is to reduce the kinetic energy of the valve - and if necessary. to the mass part connected to the valve - which it has at the end of the closing process - largely to be transferred to a mass body and temporarily stored there, so that this energy is available for the next opening stroke of the valve.
- the impulse can in each case be transmitted directly between the mass bodies or passed on via at least one intermediate link, the intermediate link either being largely stationary or being connected to one of the two masses.
- the intermediate storage of energy - when the mass body z. B. to be held by a magnet - usually takes place in a spring that exerts a restoring force on the mass body.
- the well-known EMVS represents a one-mass pendulum, while the invention can be described as a two-mass pendulum with energy transfer.
- the well-known one-mass vibration of the EMVS is divided into two half-vibrations with two masses. At the end of each half-vibration, the kinetic energy is transferred to the second vibrating mass by an impact Pulse.
- a suitable vote z. B. via the spring rate is achieved that the basic oscillation period of the valve in the ratio "three cycles closed” to "one cycle open” is set.
- a variation of the oscillation times can thus be realized on the one hand by adjusting the spring preload and / or the spring stiffness and on the other hand by known means such as magnetic retention in the end positions.
- the valve remains closed without external energy supply, since the energetic zero position is present in the closed state. If necessary, it can also be pressed into the valve seat by spring force.
- the swinging is controlled, contact of the valve with the piston can be excluded.
- the combustion chamber can therefore be optimally designed - especially without valve niches.
- the impulse-like transmission enables very steep opening flanks or a very quick opening of the valve.
- the valve opening duration can be varied by changing the spring preload.
- Fig. 1 shows an inventive device for actuating a valve in the idle state
- Fig. 2 is a flow diagram of a method according to the invention.
- the system is shown in Fig. 1 in the idle state.
- a valve 1 and a mass 1 'connected to the valve 1 by a thread and a mass 2 can exchange their kinetic energy or their impulse via an intermediate member 3 which is firmly connected to the mass 2 (m2).
- the seat ring 4 connected to the cylinder head (not shown) and a stop 5 for mass 2 are provided.
- the position of the stop 5 is fixed or adjustable so that the valve can be closed in all operating states.
- the prestressing force of the spring 6 is set greater with the help of the adjustable support 8 than the force of the spring 7 with the support 9 in order to ensure the safe closing of the valve in the idle state. Accelerating, decelerating and holding in the end position of the masses 1 '(ml) and 2 (m2) is carried out by means of electromagnets 10 (Ml) and 11 (M2).
- valve 1 Compared to known electromagnetic actuators for valve control, there is no connection between the valve 1 and the actuating element for the valve, that is to say the mass m, the two are separated from one another, the separation in FIG. 1 being between the start of the thread of the valve and the intermediate element 3.
- FIG. 2 A possible sequence of the method according to the invention is shown in FIG. 2, which can be read in conjunction with FIG. 1.
- the magnet M is energized and moves the mass m accelerated up to time t against the force of the spring 7 in the direction of the holding position (area A).
- the delay in mass m begins and ends at t when mass m reaches the stop position.
- the mass m accelerates from t and is energized
- Valve opening direction is moving. At the same time it moves
- Mass m by means of spring force in the rest position at the stop 5 and thereby covers the free travel s. This movement can also be delayed by a damping element.
- the mass m is delayed in the period from t to t.
- the valve contacts the valve seat from t to t, from t to
- the maximum power consumption of the electromagnets can be considerably reduced by the valve control according to the invention, since the recycling of the kinetic energy saves a large part of the otherwise required electrical energy in the area of large gap distances between the magnet and the component attracted by the magnet.
