Definitions
- the performance of the exhaust treatment may be improved by increasing the substrate volumes comprised in the exhaust treatment systems.
- the losses due to an uneven distribution of the exhaust flow may be reduced.
- larger substrate volumes result in a direct impact on the cost of manufacture and/or production.
- a larger substrate volume also results in a greater back pressure, which counteracts potential gains in fuel consumption, due to the higher conversion degree caused by the increased volume. It is thus important to be able to use the exhaust treatment system optimally, for example by avoiding over-sizing and/or by limiting the exhaust treatment system's spread in terms of size and/or manufacturing cost.
- Prior art exhaust treatment systems often have problems relating to inadequate soot oxidation in the filter arranged in the system to catch and oxidise soot particles, for
- the use of the active control of the administration according to the present invention results in unexpectedly great advantages for a system with two reducing steps, since the substoichiometric condition at the first reduction in this case may be maintained over relatively long periods, while simultaneously a high performance may be achieved by way of a symbiotic use of the two reducing steps.
- the catalyst device is active, and/or a coverage degree of ammonia for the first reduction catalyst device.
- the control of the first supply 220 of the first additive is carried out in such a manner, that the first reduction
- control 240 of the second supply of the second additive may be carried out based also on one or more
- Slip-catalyst SC means a catalyst which is arranged to oxidise additive, and/or to assist a selective catalytic reduction catalyst SCR with a reduction of nitrogen oxides NO x in said exhaust stream 303.
- a slip-catalyst SC is thus a catalyst, which is arranged to be able to oxidise additive in the exhaust stream, and which is arranged to be able to reduce residues of nitrogen oxides NO x in the exhaust stream.
- such a slip-catalyst SC is arranged primarily to reduce nitrogen oxides NO x , and secondarily to oxidise additive.
