A piston and cylinder construction for an internal combustion engine is provided wherein the severity of the vibrations of the reciprocating piston and cylinder have been effectively reduced to such an extent that the wear life of the piston and cylinder has been significantly prolonged. The piston carries a replaceable insert which is possessed of substantial conformability without loss of integrity, and thus remains in continuous sliding engagement with the cylinder wall thereby preventing lateral displacement of the piston within the cylinder. By reducing the severity of the vibrations, cavitation of the exterior surface of the cylinder is retarded to such an extent as to no longer present a problem. |
