Abstract

Disclosed herein is a liner for an exhaust port system of an internal combustion engine for reducing heat loss from the exhaust gas to facilitate combustion of unburned hydrocarbons (HC) and oxidation of unburned carbon monoxide (CO). The exhaust port liner is rigidly secured at one end thereof to the exhaust port and is supported at its other end by means of a peripheral sealing ring to provide an airtight liner which is free sliding at said other end to accommodate expansion and contraction of the exhaust port liner by the exhaust gas passing therethrough.
