摘要:
An OBD system is provided for monitoring an ozone depletion system that includes a catalyst coating containing MnO2 applied to a heat exchange surface on a moving vehicle over which atmospheric air passes. A physical characteristic of the catalyst coating or a material containing a physical characteristic within the catalyst coating is sensed to determine the presence or absence of the catalyst coating for detecting catastrophic failure of the ozone depleting system and/or degradation or wear of the catalyst coating to ascertain the efficiency of the catalyst coating.

The effective pore diameter of ETS-4 can be controlled without thermal treatment by selecting various combinations of cations to exchange into ETS-4. The effect that any cation mixture has on the ETS-4 can be reduced to the weighted average of the effects of each cation present.
