ABSTRACT:
A non-catalytic method for extending the life of the metal parts of an automobile muffler which comprises placing an adsorbent mass, preferably of crystalline zeolitic molecular sieve, in the internal space thereof, in sufficient amount to prevent condensation of water vapor from the engine exhaust gases on the walls thereof after engine shutdown. This procedure significantly inhibits corrosion of the metal parts.
