1. A headlight for a motor vehicle having a light source, which is arranged in a reflector, for emission of light beams in a light outlet direction, the headlight comprising:
a masking apparatus which has a mask which is movable to a first position in order to mask out at least a portion of the light beams, and which is movable to a second position in which the mask is moved at least partially out of the light beams,
an actuator unit for producing the movement of the mask, which has at least one magnet coil and a magnet yoke in order to form a magnetic flux circuit,
a hinged armature retained in an articulated manner on at least a part of the magnet yoke and is in the form of part of the mask, such that the hinged armature carries out a folding movement, and produces the movement of the mask, when current is passed through the magnet coil,
a magnet core that extends at least partially through the magnet coil, wherein, when current is passed through the magnet coil, the hinged armature is drawn against andor in the direction of the magnet core and the hinged armature becomes a component of the magnetic flux circuit, and
an opposing armature, which is located in the magnetic flux, is seated on the end of the magnet core on the hinged armature side and has a force flow edge which extends parallel to an opposing edge which is formed on the hinged armature.
2. The headlight according to claim 1, wherein the movement of the mask corresponds to a rotary movement about a hinge axis, wherein the hinge axis is arranged in the light outlet direction, and wherein the first position of the mask is a dimmed light position, and the second position of the mask is a main beam position.
3. The headlight according to claim 2, wherein the articulated retention of the hinged armature on the magnet yoke is formed by a hinge arrangement, through which the magnetic flux passes between the magnet yoke and the hinged armature.
4. The headlight according to claim 1, wherein the articulated retention of the hinged armature on the magnet yoke is formed by a hinge arrangement, through which the magnetic flux passes between the magnet yoke and the hinged armature.
5. The headlight according to claim 1, wherein the mask is formed from at least one mask arm and the hinged armature, wherein the hinged armature is in the form of a plate and extends on a plane at right angles to the extent plane of the mask arm of the mask.
6. The headlight according to claim 5, wherein the mask has a compensating mass which is in the form of a plate and extends on a plane at right angles to the hinged armature and at right angles to the mask arm.
7. The headlight according to claim 1 further comprising a spring element arranged between the magnet yoke and the hinged armature, the spring element is in the form of a spring clip and applies force to the hinged armature such that it is held in a folded position, which corresponds to a dimmed light position of the mask, when no current is passed through the magnet coil.
8. The headlight according to claim 1, further comprising a spring element in the form of a tension spring or a compression spring, and extends between the hinged armature and the magnet yoke.
9. The headlight according to claim 1, wherein the magnet core has a widened area in the form of a plate with a cylindrical attachment which extends in the direction of the hinged armature from the magnet coil, wherein the hinged armature has a cutout into which the cylindrical attachment extends.
10. The headlight according to claim 9, wherein a hinge arrangement between the magnet yoke and the hinged armature has a curved cutout in the connection area to the magnet yoke, in which a rolling surface of the hinged armature is held, which rolls along the curved cutout during movement of the hinged armature, such that a gap which exists between the cylindrical attachment of the magnet core and the cutout of the hinged armature remains essentially unchanged over the movement of the hinged armature.
11. The headlight according to claim 1, wherein the opposing armature is in the form of a planar body and extends on a plane which extends at right angles to the magnet coil, wherein a holding carriage is provided, which holds the opposing armature such that it cannot move and on which the hinged armature is arranged via a hinge arrangement, such that it can move.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for automatically controlling a stationary gaseous fueled engine, comprising the steps of:
computing an engine speed control deviation (dn) from a set engine speed (nSL) and an actual engine speed (nIST);
determining a set torque (MSL) as a correcting variable from the speed control deviation (dn) by a speed controller;
determining a set volume flow (VSL) as a function of the set torque (MSL) to establish a mixture throttle angle (DKWI, DKW2) and a gaseous fuel throttle angle;
varying the set volume flow (VSL) to adjust the gaseous fuel throttle angle by a correction factor (k); and
computing the correction factor (k) using a volume correction unit as a function of an actual system output (PAIST) and a limited set torque (MSLB), which is computed by a torque limiter from the set torque (MSL), including converting the actual system output (PAIST) to an actual system torque (MAIST), computing a quotient (Q(i)) from the actual system torque (MAIST) and the limited set torque (MSLB), and determining the correction factor (k) from the quotient (Q(i)) using an I controller.
2. The method in accordance with claim 1, including computing a mean value (MW) from the quotients (Q(i), i=1, 2, 3, . . . ) within a computation interval, and determining the correction factor (k) with the I controller based on the mean value (MW).
3. The method in accordance with claim 2, including limiting the correction factor (k).
4. The method in accordance with claim 1, wherein, in a steady-state operating condition, the correction factor (k) is set as the current value for the correction of the set volume flow (VSL), and in a non-steady-state operating condition, the last correction factor (k) determined during a steady-state operating condition is kept as the current value for the correction of the set volume flow (VSL).
