摘要： A system and an on-board-diagnosis method is provided for an exhaust aftertreatment system of an engine including a diesel particulate filter unit which encompasses a particulate filter in which soot can be oxidized by NO2 and constituents of the exhaust gas are deoxidized in a nitrogen-oxides reduction unit arranged downstream of the diesel particulate filter unit, wherein the exhaust gas flows from the diesel particulate filter unit to the nitrogen-oxides reduction unit. The on-board-diagnosis method includes estimating an NO2 content upstream of the nitrogen-oxides reduction unit, measuring at least one of an NOx or NO2 content upstream of the nitrogen-oxides reduction unit, performing a comparison between the estimated and the measured contents, and, based on the result of the comparison deciding on at least one conditioning step of the diesel particulate filter unit.

摘要： A method and an arrangement are provided for maintaining the oxidation of NO to NO2 in an oxidation catalytic converter arranged in a vehicle, the vehicle including an internal combustion engine which in operation emits exhaust gases to an exhaust gas after treatment system including the oxidation catalytic converter. A predetermined quantity of hydrocarbon is delivered to the exhaust gas aftertreatment system or the engine over at least one predetermined time interval for the purpose of maintaining the working temperature or regenerating an exhaust gas aftertreatment unit. The quantity of hydrocarbon is delivered to the exhaust gas aftertreatment system or to the engine through an injection with at least one predetermined fragmentation frequency and an injection period in order to maintain an NO2 production in the exhaust gas aftertreatment system that prevailed immediately prior to said time interval for the hydrocarbon injection.
