Abstract
A seal of the upper area of a wet cylinder liner with respect to the crankcase of a reciprocating piston internal combustion engine and a method of making the same, whereby a liner collar of the cylinder liner rests with a collar surface on a support surface at the crankcase; a thin layer of silicon rubber or of other deformable sealing material is applied between the collar surface and the support surface either prior to or during the pressing-in operation of the cylinder liner into the crankcase by applying such a quantity of the silicon rubber or deformable sealing material into an annular space formed by a recess in the cylinder liner underneath the liner collar and/or by a chamfer at the crankcase, that toward the end of the pressing-in operation the sealing material is pressed between the collar surface and the support surface and forms thereat a layer.
