摘要： The invention is a nitrogen oxide trap separate catalyst phases. One of the phases is platinum on a porous support and another is alkali metal or elements and alkaline earth elements on another porous support. The phases may be provided as an intimate mixture or as layers in the trap. The trap may be used in an internal combustion engine exhaust gas catalyst system. During lean-burn operation of the engine the trap adsorbs nitrogen oxides and releases the nitrogen oxides during decreased oxygen concentration in the exhaust gas.

摘要： A nickel-based catalyst is provided for reducing carbon monoxide, hydrocarbon emissions, and nitrogen oxides from vehicle exhausts. The catalyst is impregnated directly onto a carrier which is non-reactive with nickel. The nickel is contained on said carrier at a loading of between about 2 to about 20 wt %. When used in a vehicle exhaust gas treatment system, the catalyst provides improved efficiency in reducing CO, HC, and NOx emissions over the use of conventional three-way-catalysts.

摘要： A method and system are provided for monitoring exhaust gas conversion efficiency of a catalytic converter during operation of an internal combustion engine coupled to the catalytic converter. The system includes an upstream exhaust gas sensor interposed the engine and the catalytic converter for generating a first signal based on the exhaust gas upstream of the converter. A downstream exhaust gas sensor is interposed the catalytic converter and atmosphere for generating a second signal based on the exhaust gas downstream of the converter. A phase shift detector is provided for estimating a phase shift between the first and second signals. A processor is provided for aligning the first and second signals such that the resulting phase shift between the first and second signals is substantially an integer multiple of &pgr; radians and for determining conversion efficiency of the catalytic converter based such phase aligned first and second signals. With such method and system, average error of the calculated index ratio using such system and method and the theoretical average error in index ration (IR) is minimized when the phase shift between the upstream and downstream sensor signals is substantially an integer multiple of &pgr; radians.
