Zusammenfassung: | The internal corrosion of metal mufflers used in conjunction with internal combustion engines is substantially retarded by maintaining in the external void space thereof an adsorbent mass of a combination of crystalline zeolites having the crystal structure of chabazite and the crystal structure of faujasite. These adsorbent compositions exhibit a synergistic effect on corrosion retardation. Novel muffler devices per se are also disclosed. |
