Definitions
- the invention relates to an internal combustion engine for a motor vehicle having the features according to the preamble of claim 1.
- A1 is an internal combustion engine with a combustion chamber known.
- the coating is applied in particular on a piston head, an inner cylinder surface and a cylinder head inner surface.
- the catalytic coating has a nanostructure constructed of structural elements of elongate shape, wherein the structural elements adhere with one end to the coated surface and end with their second end in the combustion space or the exhaust-gas-carrying space.
- Such a coating is preferably carried out by the methods of gas flow sputtering or magnetron sputtering.
- the catalytic coating is intended to assist in the oxidation of coking residues of the combustion process. By a high catalytic activity, a high turnover rate is to be ensured.
- the layer thickness should be between 0.1 .mu.m to 50 .mu.m.
- the heat conduction coating has a thermal conductivity in the range of 0 to 70 * 10 -6 metric units and correspondingly 93 * 10 -6 metric units for aluminum pistons.
- the piston also has in the region of a peripheral surface of a top land a thermally conductive abrasive layer, which wears during the initial operation of the internal combustion engine to adapt the piston to the cylinder bore wall as possible with little play.
- the thermal conductivity of the abrasive layer is achieved by conductive particles or conductive flakes of copper or aluminum in a layer matrix.
- the layer matrix comprises a mixture of at least two elements, wherein the two elements are selected from a group consisting of graphite, molybdenum disulfite and boron nitride.
- the piston has a piston head and a piston skirt.
- the piston head is connected to the piston skirt by a retaining spring.
- the retaining spring should allow a compensation of micro-movements as a result of different thermal expansion of the piston crown and the piston skirt.
- the heat transfer between the piston head and the piston skirt is hindered by a coating of the piston crown.
- the coating is applied to at least one seat surface of the piston crown, with which the piston head bears against the piston skirt.
- the piston head can thus assume much higher temperatures than the piston skirt, without transferring too much heat to the running surfaces.
- the coating can also be formed on the combustion chamber facing side of the piston crown.
- the coating may comprise titanium or titanium compounds, ceramic, hardcoat or other materials applied by chemical or physical vapor deposition.
- a corresponding cylinder of metal or of a ceramic has an inner bore which forms a piston guide surface.
- the piston guide surface is equipped with a hard coating. This coating is a few tenths of a millimeter or microns thick.
- hard materials come into consideration as a coating, so carbides, oxides, nitrides and diamond coatings.
- the coating may consist of polycrystalline diamond or be formed as a diamond-like carbon coating (DLC "diamond like carbon").
- the coating may contain metal-containing hydrocarbon (Me: CH), suitable as the metallic doping, for example, titanium, tungsten, boron or their particularly hard carbide phase, which at the same time has a favorable affinity for carbon.
- metal-containing hydrocarbon Mo: CH
- suitable as the metallic doping for example, titanium, tungsten, boron or their particularly hard carbide phase, which at the same time has a favorable affinity for carbon.
- amorphous hydrocarbon (a: CH) or of tetragonally coordinated carbon (a: C) is conceivable.
- the piston has two sliding portions each in the form of a ring whose closed cylindrical circumference each defines a sliding portion of the piston.
- the material of the sliding sections consists of mesophase graphite or ultrafine grained graphite.
- the rings can be made from mesophase graphite by means of primary shaping.
- DLC coating diamond like carbon
- thermally and tribologically highly stressed components of an internal combustion engine such as bolts, piston rings, connecting rod bearings, running surfaces of the piston and the like, so that friction, wear and adhesion tendency are reduced.
- a first DLC coating is applied to the component by means of plasma-assisted chemical vapor deposition, this first DLC coating assuming the function of a bonding agent layer.
- another DLC coating is applied, which has a reduced stiffness, hardness and lower residual stress than the first DLC coating.
- a DLC coating namely a coating of diamond-like carbon, is to be understood as meaning all layers listed in VDI 2840 in Group 2.
- DLC coatings consist essentially of carbon bound in sp2 and / or sp3 bonding, the bond character substantially determining the property of the film.
- Particularly advantageous is an amorphous, hydrogen-containing, metal-free DLC coating in which the two types of bonding in the ratio 60 to 80 to 20 to 40 are present.
- the generic type internal combustion engine is not yet optimally formed. Efficiency and performance improvements of internal combustion engines can lead to higher thermal loads.
