Abstract
The invention relates to an internal combustion engine structure, and addresses the problem of preventing coolant and lubricant from mixing therein. A seal structure is provided for sealing between an engine block 10 and a cylinder liner 34 in an internal combustion engine. The seal structure 40, 42 comprises an annular insert member preferably made of a high temperature resistant resinous material. The insert 100 fits in a recess 136, 134 in the engine block 98 and encircles the cylinder liner 94. A resilient seal member 110, 112, 114 in a groove 104, 106, 108 in the inner surface 130 of the insert 100 seals against the cylinder liner 94.
