Abstract
The invention provides an exhaust gas cleaning oxidation catalyst and in particular to an oxidation catalyst for cleaning the exhaust gas discharged from internal combustion engines of compression ignition type (particularly diesel engines). The invention further relates to a catalysed substrate monolith comprising an oxidising catalyst on a substrate monolith for use in treating exhaust gas emitted from a lean burn internal combustion engine. In particular the invention relates to a catalysed substrate monolith comprising a first washcoat coating and a second washcoat coating wherein the second washcoat coating is disposed in a layer above the first washcoat coating.
