Definitions
- the invention relates to an internal combustion engine, in particular stationary gas engine, with a piston that runs in a cylinder liner, which inside the crankcase is arranged and which in the region of its upper, the cylinder head adjacent edge having an annular flange for support in the crankcase in the axial direction, with a on the outside of the cylinder liner extending coolant channel and with a the inside of the cylinder liner in the region of its upper edge arranged something over the inner surface of the cylinder liner projecting scraping ring for scraping the Outside of the piston in the area adjacent to the end face of the piston area.
- An internal combustion engine of this kind is e.g. already known from CH 672 353.
- the scraping ring of this Internal combustion engine prevents the deposition of combustion residues at the Outside of the piston in the area adjacent to the end face of the piston, which otherwise over time, in particular to impair the function of the piston rings being able to lead.
- the object of the invention is to provide an internal combustion engine, in which the Operational reliability and service life over the known engines of this type is improved. This succeeds according to the invention having the features of the characterizing part of claim 1.
- the invention consists in that in the problem according to the invention in first and foremost not a mechanical but a thermal problem. Due to thermal stresses, it can namely in the course of time to a delay or a loosening of the scraping ring come. To counter this, the provided measures according to the invention.
- a piston 110 which in a Cylinder liner 101 is running.
- the cylinder liner has in the area of its upper Cylinder head 102 adjacent edge 103 on an annular flange 104.
- This ring flange 104 serves for the axial support of the cylinder liner on the piston housing 105, which over the cylinder head 102 is acted upon in the axial direction.
- the cylinder head gasket 106 Between ring flange 104 of Cylinder liner 101 and cylinder head 102 is the cylinder head gasket 106 and in Cylinder head 102 is visible in this sectional view of one of the valves 107.
- the Centering of the cylinder liner 101 in the crankcase 105 takes place in the area 108 briefly below the annular flange 104. Between crankcase 105 and cylinder liner 101 extends to this area 108, a cooling liquid passage 109th
- FIG. 2 which also forms part of a longitudinal section through a cylinder of a larger engine, in particular a stationary gas engine, is now the Invention be explained.
- valves are the (the prior art corresponding) valves in this Fig. Not visible.
- the piston 10 is running in one Cylinder liner 1, which is disposed within the crankcase 5.
- this is provided with an annular flange 4, via which it is supported in the axial direction in the crankcase 5 on a flange 11.
