nox storage
Method of making a NOx storage material.
Nox storage materials and traps resistant to thermal aging.
In addition this system comprises NOx storage catalyst.
The NOx storage reduction catalyst is made to release the NOx.
Regeneration of NOx storage catalysts.
More coating material per unit volume results in a greater NOx storage capacity.
Preparation of NOx storage material.
The NOx storage catalyst consists of a NOx storage catalyst and a precious metal catalyst.
The exhaust gas control catalyst may be a NOx storage reduction catalyst.
The NOx storage reduction catalyst gradually accumulates NOX if use is continued.
The SOx is then emitted from the NOx storage reduction catalyst.
Thus, the NOx storage catalyst purifies the excessive reductant more efficiently.
This SOx is stored together with the in the NOx storage catalyst.
This recovers the NOx storage ability of the catalyst.
The supplied reducing agent reduces the SOx occluded by the NOx storage reduction catalyst.

Method of making a NOx storage material TECHNICAL FIELD.
A NOx storage reduction catalyst 36 is located at the most upstream section.
Under these conditions, the overall NOx storage capacity is evaluated.
In this case, the NOx storage reduction catalyst stores NOx and simultaneously stores SOx.
As a result, it is possible to suitably regenerate the NOx storage reduction catalyst.
Incidentally, the NOx storage reduction catalyst 28 will be described later.
The surface of the exhaust filter 33 is coated with NOx storage reduction catalyst.
The NOx storage amount of the NSR catalyst 30 may be calculated by a well-known method.
Thus, a NOx reduction reaction in the NOx storage reduction catalyst can be accelerated.
FIG . 22 is a view showing an NOx purification rate and NOx storage rate.
Therefore, an exhaust purifying apparatus having a NOx storage reduction catalyst normally performs poisoning elimination.
A NOx storage reduction catalyst 36a is housed in the first catalyst converter 36.
As a result, the NOx which is released from the NOx storage catalyst is reduced well.
That is, the NOx storage catalyst 14 suffers from SOx poisoning.
Therefore, the amount of SOx which is stored in the NOx storage catalyst gradually increases.
Thus, there is a need to provide improved NOx storage materials and methods for their manufacture.
FIG . 2 shows an enlarged schematic cross-sectional view of an NOx storage reduction catalyst.
The switching valve 52 is arranged between the NOx storage reduction catalyst 16 and the oxidation catalyst 17.
A first air-fuel ratio sensor 42 is located upstream of the NOx storage reduction catalyst 36.
The spatial velocity of the exhaust gas at the NOx storage reduction catalyst 16 becomes slower.
The oxidation catalyst 17 is connected through the exhaust pipe 12 to the NOx storage reduction catalyst 16.
Thus, the following description will focus on the NOx storage reduction catalyst 36a.
A first exhaust temperature sensor 44 is located between the NOx storage reduction catalyst 36a and the filter 38a.
