| 20090169451 | Catalytic reduction of NOx - A system for NO | 07-02-2009 |
| 20100199646 | Catalytic reduction of NOx - A system for NO | 08-12-2010 |
| 20110154807 | NOx TRAP - A NOx trap comprises components comprising at least one platinum group metal, at least one NOx storage material and bulk ceria or a bulk cerium-containing mixed oxide deposited uniformly in a first layer on a honeycombed substrate monolith, the components in the first layer having a first, upstream, zone having increased activity relative to a second, downstream zone for oxidising hydrocarbons and carbon monoxide, and a second, downstream, zone having increased activity to generate heat during a desulphation event, relative to the first zone, wherein the second zone comprises a dispersion of rare earth oxide, wherein the rare earth oxide loading in the second zone is greater than the loading in the first zone. An exhaust system for a lean burn internal combustion engine, a vehicle comprising a lean burn internal combustion engine and the exhaust system and methods of making the NOx trap are also disclosed. | 06-30-2011 |
