摘要
An oxidation catalyst composite, methods and systems for the treatment of exhaust gas emissions from an advanced combustion engine, such as the oxidation of unburned hydrocarbons (HC), and carbon monoxide (CO) and the reduction of nitrogen oxides (NOx) from a diesel engine and an advanced combustion diesel engine are disclosed. More particularly, washcoat compositions are disclosed comprising at least two washcoat layers, a first washcoat comprising a palladium component and a second washcoat containing platinum and at least about 50% of the total platinum is located in the rear of the catalyst.
