  • Sealing arrangement for wet cylinder liners
    Patent number: 4417549
    Abstract: A sealing system is intended for wet cylinder liners and having a flange seat on the crankcase of internal combustion engines. Sealing rings are respectively provided in the recess and in an annular groove arranged in the area of the upper guiding portion of the liner. The annular groove should not reduce the length of the guiding portion by more than 40%. In this manner, salt crystals forming as cooling water evaporates are prevented from penetrating up to the top sealing ring, so that this ring will not be corroded, and its sealing action is maintained.
