Abstract
Official abstract text for this publication.
The invention provides a method for purification of exhaust gas from a diesel engine in a system, which comprises a device for selective catalytic reduction and a diesel particulate filter preferably at least partially covered by a catalytic layer installed downstream of the device for selective catalytic reduction. A device for catalytic oxidation is installed upstream of the device for selective catalytic reduction and/or between the device for selective catalytic reduction and the diesel particulate filter. A device for injection of a controlled amount of reductant is installed inlet of the device for selective catalytic reduction, and a device for injection of a controlled amount of hydrocarbon is installed inlet of the catalytic oxidation.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for purification of exhaust gas from a diesel engine in a system, the method comprising the steps of: providing: a catalyst for selective catalytic reduction; a diesel particulate filter at least partially covered by a catalytic layer installed downstream of the catalyst for selective catalytic reduction; and a first catalyst for catalytic oxidation installed upstream of the catalyst for selective catalytic reduction and/or a second c…
