What is MKC?
MKC is a foil condenser, whose function is based on fast memory and delivering energy.
By applying the condensers at oscillation-relevant points swinging construction units (feathers/springs, shock absorber, wishbone, frame parts, motorcycle fork among other things) in their vibration response are affected positively. There is then higher forces necessary, in order to bring the vehicle from the peace.
Example of use for the mounting of MKC at a front axle.
The chassis optimization MKC's will become attached e.g. to foremost rear axle, along and cross beams, the shock struts and shock absorber, the feathers/springs, the knuckles and the steering element parts.

Example of use for the mounting of MKC at a rim.
In order not to disturb the optical impression of a rim, it is advisable to attach MKC on that inside side.
MKC Digi 9 is an aluminum panel, on which a programmed layer is applied for material influence.
The Digi 9 is glued on with its self adhesive side, the clean and grease-free underground which can be worked on. It can be covered then additionally with underbody protection, or also over-painted.
Example of the optimization - motorcycle chassis
Vibrations construction units of engines, machine equipment and vehicles, burdening statically by dynamic and, are absorbed by the MKC Technick.
- Oscillations and impact sound reduces
- decreases the wear of dynamically loaded construction units
- the road-hugging property and curve stability of vehicles improves
- the Aufschwingen of vehicles after the over driving of bumps strongly reduces
With the MKC technology solutions of oscillation and sound problems are possible, which would be inconceivable by the associated expenditure otherwise. there is not necessary mechanical changes and changes.
MKC are self adhesive foil condensers, which are glued on their energy on the carrier underground, i.e. the construction unit on that you, refer and the carrier underground, and/or under or over this underground flowing gas liquid flows affect.
The physical explanations for the cause of the existing and measurable positive changes by the MKC at engines, machine equipment, water, country and aircraft to be reached, lead into quantum physics.
Among other things becomes by the MKC, due to the contact potential difference between the carrier underground and the MKC, which increase modulus of elasticity of steel.
The individual influences of the MKC were proven in the last years by lab tests and confirmed by results of measurement and experiences from practice.

With the MKC technology in the further process of this lecture will more near be described, reach we among other things an oscillation reduction - or around it to say more exactly a shortening of the decaying procedure of a erzungenen oscillation, a reduction of the transmission of oscillations and thus a reduction in the impact sound.
A reduction of oscillations means less wear and a higher availability of plants.
At present we know that by the employment of the MKC technology at Diesels and petrol engine plants a better course of a torque is reached. The fuel economy amounts to 2.5 - 4.0%. That could be proven so far for engines up to 600 KW.
From lab tests it lets itself deduce that a change in the heat transition can be achieved with convection heat exchangers. Practice investigations for this are pending at present still.
Technology of the MKC
Materials, like metal, plastics, wood, ceramic(s) and other composite materials consist of atoms and molecules, which are held together by electrical forces. These electrical forces are produced by components of the atoms and molecules. This are mentioned the electrically negatively charged particles, electrons, and those electrically positv charged particles, protons mentioned.
The effect of these electrical forces is determined in the materials technology and material testing by traction tests. The size determined by these attempts is called modulus of elasticity. It is a material constant, which is dependent on the respective composition of the material and its surface finish. Modulus of elasticity (designated in the Formelsprache with E), the density (p) and the installation and/or material length (L) determine the natural frequency (f) of the respective material.
A further important material constant is the electron work function. This size indicates, which energy is necessary, around an electron from the material zulösen. The unit for this is the electronvolt, shortened eV. brings one materials with different electron withdrawal work in contact, then a contact potential difference is formed.
This contact potential difference represents a tension, which arranges the electrons with lower electron work function to change over into the material which exhibits a higher electron work function. One can imagine this procedure, as with a hydro-electric power plant, with which the Wassermassen of an artificial lake (the electrons) in a more deeply lying valley or a more deeply lying lake fall down.
On the basis of these bases and the realization that the natural frequency of a material in accordance with the equation
both on the modulus of elasticity E and on the material density p and the length L of the material is dependent to increase against the normal approach the density and/or the weight to increase for a possibility looked modulus of elasticity by an outside interference. Here electrical and magnetic fields present themselves, which reinforce the material. (Electrostriction and/or magnetostriction).
By means of developed condenser chip (shortened MKC), material-affecting of MKC international for the most different ranges of application and refugees, can it possible such a change of the modulus of elasticity E be attained. This takes place over the electrical fields developing with contact of different materials, which are produced by the contact potential difference developing between the chip and the material. If these electrical fields are accelerated now by a mechanical movement of the material, then develop additionally magnetic fields, which reduce the moved material similarly an eddy current brake in its peak-to-peak swing.
MKC stands for subject, and/or affecting condenser chip. MKC´s are self adhesive foil condensers, which are glued on your energy from the carrier underground, i.e. the material on that them to refer and this material, and/or the flow attitude of liquid and gaseous media in the boundary layer to change. A cause for (local) the change of materials is the difference of potential between the MKC and the material on which it is applied.
The MKC foil condenser was developed by Mr. Bernhard Hue at the beginning of the 80íger years and is since 1994 German patent and eingetragenenes registered trade mark.
The MKC foil material consists 55 of my a strong self adhesive foil is imprinted on the one condenser circuit.
The size/the assigned MKC depends on the mass of the workpiece on which it is glued on and which becomes lively frequency range in which this workpiece.
Originally exclusively for the improvement of the energy entry into the ignition of Otto engines developed, end of the 80iger was discovered years by coincidence that by the MKC changes in the physical characteristics of materials are caused.
These changes were examined and occupied by several studies at universities.
To it belong in particular:
- Attempt at the Prandl´ pitot tube
- Traction test with St37
- Attempt to the speed profile of liquids
For the first time 1985 used in motor vehicles
For approx. 1990 used in the most different ranges of application
Since October 1994 patents
The illustrations right show the difference of the ignition spark in a conventional ignition system for Otto engines contrary to one with MKC foil condensers modified ignition system.
Instead of a single ignition we reach 40-50 ignition break-throughs per ignition and thus a better burn, a better efficiency.
Depending upon execution of the engine it can become necessary after the installation of MKC technology, the attitude, to change and/or the Bedüsung of the carburetor since beside changed ignition the mixture one changes.
With engines with Lamdaregellung that is generally not necessary.
Even if the effect of the MKC is measurable, it falls heavily a technology to accept, whose physical background is not yet completely investigated.
If before 30 years a notebook had been introduced to you after today's conditions, which has the arithmetic performance of a hardware, which would hardly have found at that time in a wardrobe place, would be you just as sceptically.
We learned that mechanical oscillations by auxiliary masses, by absorbers and constructional measures to be reduced to be able.
With the MKC technology we have an almost massless material, with which without mechanical changes in existing machines, plants and vehicles changes can be achieved regarding the transmission of impact sound, regarding quiet running and efficiency.
Increase of the elastic module of steel and of other materials
Reduction friction resistance between flowing medium and überströmter surface
Increased energy entry into the burn process
Right you see the result of a measurement of the Prandl´ pitot tube. In the case of this measurement the flow rate profile was taken up by air before and after the attachment of MKC foil condensers at the pipings. On the y axis the flow rate is laid on in m/s. On the x axis the distance of the transducers from the pipe wall. For technical reasons could not be based more near than 3 mm on the wall.
Therefore the curve breaks off there. The blue curve shows the flow rate without MKC. The red with MKC. Close one of the wall was reached an increase of the flow rate around 12%. A comparable test result was reached for liquid media in another laboratory test.
MKC technology - flow resistance
From practice: To 27.12.99 in co-operation with threw De Gerlien van Tiem a bow thruster plant with MKC technology equipped. The stake course measurement resulted in a difference of 2200 kg (afterwards) to 1800 kg (before), so that with consideration of all possible tolerances an improvement was reached around at least 12%.
We will reach but imagine not always 12%, you a ship or an airplane that 5% less flow resistance have. The same speed lets itself obtain with a by far smaller fuel consumption.
In an attempt with the HSVA (Hamburg shipbuilding laboratory) the trend reduction of flow resistance was confirmed by MKC foil condensers.
MKC - Technology: Modulus of elasticity change
Physical fundamentals by Dr. Stephan Zöpfel
1. Modulus of elasticity
Modulus of elasticity of materials is defined as mechanical preservation size. I.e. it is considered as material constant between the mechanical stress A and the expansion s from the quotient of the aspect ratio x of the material to its origin length L arises, defined.
E forms a tensor, i.e. the quantity E is spacedependent. Space dependence can be zurückgefiihrt on it that depending upon adjustment of the elementary cells and the symmetry of the crystal different atomic distances and cohesive forces henschen. We want however for the simplification of the view, but however without restriction of the public only one dimension to regard here and can without a three-dimensional and tensorielle view to thus do.
1. Modulus of elasticity
Defined as mechanical preservation size of materials
E is a tensor => E is spacedependent
Causes of space dependence:
Adjustment of the elementary cells
Symetrie of the crystal
Different atomic ones of distances
different cohesive forces
1.l. Potential model
The directionality gives us however a first reference to the cohesive forces. They are electrical nature and are based on the coulomb reciprocal effect between the positively charged atomic nuclei and the negatively charged electrons. One can represent this in the long-proven potential model (fig. 1). On the x axis (abscissa) the place is indicated to 1 angstrom in 1/10 Nm = and on the y axis (ordinate) is indicated the connection energy in eV = 1.602 * 10-19 VAs.
That is the energy, those is necessarily a simply loaded elementary particle, is it electron or proton or simply loaded ion from the material connected to extract. With atomic trunks is this with the energy to usually compare is needed, in order to shift an atomic trunk a place in the lattice system.
This connection energy corresponds to the relative to easily measurable and accessible electron work function the vacuum level, which is defined to 0 eV. If now an electrical field is put on from the outside, the potentials in the following form are bent (fig. 2). A linear sinking of the potentials results to a side. This means at the same time that more energy must be spent, in order to stretch on mechanical way the material. This corresponds to an increase of the modulus of elasticity.
Cohesive forces are based on the coulomb reciprocal effect
Larger coulomb reciprocal effect => higher elastic module
The same effect one can reach, if one brings two materials with different electron work functions, which correspond to the Fermi levels of the materials, in contact, because then must because of the continuum condition the potentials without leap adjust itself. They are first arranged as in fig. 3. They see there on the side of the material which can be treated a metal with its conduction band half occupied with electrons, in whose center thereby also the Fermi level is.
Among them they see the valence band, which contains of atomic trunks to the bound electrons. In the center of the conduction band of the metallic material is the Fermi level. With the other material, the MKC, it acts around a material with substantially lower Fenniniveau, is it now an insulator with vacant conduction band, and with it with a Fermi level lying between valence and conduction band or a metal with substantially higher withdrawal work. The difference of these two Fermi levels is called also contact potential.
1,2 contact potential
Contact potential is the difference of two Fermi levels in contact of materials brought in eV.
1.3. Contact potential difference
We accept here first of all without restriction of the public an insulator. One brings it with the metallic material which can be treated in contact is formed a contact potential difference in such a way. It causes that the electrons from the side with the smaller electron affinity, on which, ignores side with the higher electron affinity, but the substantially lower lying Fermi level, until the two Fermi levels adjust themselves (Abb.4).
Thus the side is charged negatively with the higher electron affinity and with the low electron affinity positively, whereby the contact potential difference is formed the one further buckling of the normal unimpaired potential structure produced.
Thus the potential process is changed in similar way, as an electrical field is put on if from the outside. Because by the density distribution of the electrons an electrical field is produced that as in the case of the active creation works.
From lab tests it is well-known that by the MKC, and/or the utilization of the contact potential difference between
the MKC and the Trägerwerkstoff steel for an increase of the elastic module around 7,5 - 10% lead.
Thus we have to change the possibility afterwards a material and to reach a shift of the natural frequency. In practice that means that we can to detune and thus a reduction regarding the transmission of impact sound and oscillations achieve a mechanical system.
I hope to give with this short lecture a first idea of the MKC technology to you.

How MKC works - simple explains
The impact of the MKC is with a small broom, which is hooked with its bristles in the bristles of a large broom, comparison bar. The bristles correspond to the electrical and magnetic fields, which develop themselves due to the contact potential difference training between the materials. The starting points of the bristle bundles correspond in each case to the atoms in the MKC and in the material. If one drives past now with the finger at the large broom, then one recognizes that the bristle bundles within the range of the small broom cannot be so easily moved any longer.
This corresponds to the increase of the modulus of elasticity in the material. That is, around the individual atoms (bristles) just as far to move, now a larger Kraft is necessary than before. In addition now a shorter length of the large broom (material) for oscillations becomes freely mobile by the small broom (MKC), which leads apart from the change of the modulus of elasticity to another natural frequency of the material, i.e. the deflection of the total material becomes smaller.
