Abstract: The invention is a method of treating exhaust gases generated by an internal combustion engine using a NOx trap in the exhaust gas system. The method comprises locating an essentially alkaline earth-free nitrogen oxide trap in the exhaust gas passage and cycling the air/fuel ratio of the exhaust gases entering the trap between lean and rich, such that the trap absorbs nitrogen oxides during the lean cycle and desorbs the nitrogen oxides when the concentration of the oxygen in the exhaust gas is lowered as during a rich cycle. The trap comprises: (a) a porous support material comprising mostly .gamma.-alumina and (b) metals consisting essentially of 0.1 to 2 wt. % tungsten oxide and precious metal comprising 0.5 to 4 wt. % platinum deposited on the support, the amount of said metals being individually based on the weight of said support material. The desorbed nitrogen oxides may be converted over the precious metal to N.sub.2 and O.sub.2 by reductants like hydrocarbons present in the exhaust gas.

Abstract: The invention is a sensing method and an oxygen sensor for detecting a change of oxygen partial pressure in an ambient atmosphere through a change of a measurable physical property of a sensing material. The sensor includes a sensing material selected from metal or its oxides which, when at an elevated temperature and exposed to a gas containing a changing partial pressures of oxygen, is capable of changing from one metal or metal oxide phase to another such oxide phase and vice versa. Associated with such phase change is a change in a measurable physical property of the material. The sensor also includes heating means, connectable to a power source, maintaining a temperature gradient across the sensing material since it is critical that the sensing material exist in at least two phases during active sensing. An output signal is furnished in response to the change in a physical property, like electrical resistance, of a portion of or of the entire material in response to change in oxygen partial pressure.
