ABSTRACT:
An exhaust catalytic converter for a Diesel engine that provides for enrichment of the Diesel engine exhaust with hydrocarbons that support nitrogen oxide conversion in the catalyst. The system includes a first catalytic converter stage that is designed for NOx conversion in a first temperature range utilizing a first part of the HC enrichment volume in the exhaust and has a suitable first catalyst material charge for the purpose as well as a second catalytic converter stage that follows the first in the exhaust flow direction, the second stage being designed for NOx conversion in a second temperature range higher than the first and utilizing a second part of the HC enrichment volume in the exhaust, and containing a second catalyst material charge suitable for the purpose. By suitably tuning the system with HC enrichment, reduction of emissions of solid and volatile particles in the Diesel exhaust can be achieved.
