Abstract
A replaceable monolithic, hollow, generally cylindrical cylinder liner formed of hot pressed silicon nitride adapted for operating at the high engine temperatures caused by fuel combustion and friction within the liner without need for liquid cooling thereof. The liner includes a surface adjacent its outer end for forming a radial press fit with the inside surface of the cylinder cavity and a stop-engaging surface formed on the cylindrical liner surface spaced axially inwardly of the press fit surface or along the innermost face of the liner for engaging an engine block liner stop within the cylinder cavity.
