Multi-partite exhaust gas line

摘要

An exhaust gas line for a piston internal combustion engine assembled of several parts consists of an inner pipe line conducting the exhaust gases and of a housing surrounding this pipe line with a spacing. Each of the housings contains a cooling liquid space. The cooling liquid spaces of adjacent housing are connected with each other by a connecting nipple. The connecting nipple, axially displaceable in the recesses, permits an expansion compensation between adjacent housings.
