Method and device for cleaning exhaust gas containing nitrogen oxide from an internal combustion engine |
摘要 |
The method and the novel device clean exhaust gas containing nitrogen oxide from an internal combustion engine. Liquid ammonia is preferably added as reducing agent from a reducing agent reservoir through a reducing agent line and a metering device through the use of open loop or closed loop control synchronously and/or phase-displaced in a relation to the corresponding output of exhaust gas from the combustion chamber and in portions adjusted to the quantities of NOx generated. The synchronized and quantitatively adjusted addition of ammonia allows for NOx and ammonium emissions to be kept low with a catalytic converter disposed downstream and having a small storage volume.
