EXHAUST LINE FOR AN INTERNAL COMBUSTION ENGINE |
摘要 |
<p>An exhaust system for an internal combustion engine comprises a catalysed particulate filter comprising a NOx absorbent capable of absorbing NOx contained in an exhaust gas when the composition of the exhaust gas is lambda >1, and capable of releasing the NOx absorbed in the NOx component when the exhaust gas composition is 1>=lambda, characterised in that the exhaust system further comprises a catalyst capable of oxidising NO to NO2 at least when the air-fuel ration of the exhaust gas is lean.</p> |
