Definitions
- the invention relates to a piston-cylinder device of an internal combustion engine according to the preamble of patent claim 1.
- the piston running layer is regularly of a metallic type and is applied galvanically.
- the invention is concerned with the problem of creating an economically producible piston running layer, the properties of which are at least not inferior to the layers previously applied galvanically.
- the R value specified in the claims is a value defined according to the ISO standard and denotes the arithmetic average value of the peak heights of the surface peaks forming the roughness.
- the piston-cylinder pairing according to the invention is to be used in particular in internal combustion engines for lawnmowers, brush cutters, brushcutters and stationary engines.
- An exemplary embodiment is shown in the drawing, which shows a section through a piston-cylinder pairing.
- the piston 1 has a diameter of approximately 42 mm and is guided in a cylinder 2 of a two-stroke engine.
- the base material of the piston consists of an aluminum-silicon alloy of the following composition, given in percent by weight:
- a running layer 3 made of graphite bonded in resin is applied in each case to the bearing areas of the piston skirt opposite in the pressure and counterpressure directions.
- a corresponding additional running layer 4 can be applied to the top land area of the piston 1 lying above the only piston ring groove 5.
- the running layer 4 in the top land area can also be dispensed with.
- the individual ring webs can also be coated.
- the running layers 3, 4 have both in the shaft and in the top land area each a thickness of about 20 mm.
- the structure and the composition of the running layers 3, 4 are as follows.
- the layer in question is applied by the screen printing method known in this field.
- the graphite is bound in the hardenable polyimide as a binder within the running layers.
- the graphite content within the hardened layer is approximately 40 percent by weight.
- the material to be applied to produce the layer in the screen printing process contains a solvent, which can be, for example, N-methyl-pyrrolidone (NMP).
- NMP N-methyl-pyrrolidone
- the proportion of the solvent in the layer starting material to be applied is approximately 50 percent by weight.
- the particle size of the graphite incorporated in the layer is between 1 and 10 microns.
- the layer applied in the screen printing process becomes about 200 C at about
- the material forming the counter-path of the cylinder 1 is an aluminum alloy of the following composition, given in weight percent.
- a The piston ring 6 inserted into the piston ring groove 5 consists of an STD material of the following composition given in weight percent:
- the tread geometry of the piston ring 6 is crowned.
- Such a piston ring is specified for the dimensions of 42 mm x 1.5 mm used here by the German standard DIN 70910 DI Tl B.
- the piston-cylinder device described above with a piston of a diameter of approximately 42 mm is intended for use in a power range in the order of approximately 20-40 kilowatts / liter.
