ABSTRACT:
A liner of thin wall heat resistant material is positioned to receive exhaust gases from two adjacent exhaust port passages of an internal combustion engine, downstream from the exhaust valves. Each liner has a single outlet opening formed within a circular projection. A support piece has a central opening which receives said projection, and the support piece has an outer peripheral skirt which is mounted in a recess at the outer end of a dual exhaust port passage. The support piece also serves to block flow of exhaust gases in the space between the liner and the enclosing exhaust port passages. In a modification, each liner receives exhaust gases from only one exhaust valve.
