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

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 NOxgenerated. The synchronized and quantitatively adjusted addition of ammonia allows for NOxand ammonium emissions to be kept low with a catalytic converter disposed downstream and having a small storage volume.

The mechanical locking system as claimed in claim 1, wherein the first panel and the second panel form a laminated floor. 21. A mechanical locking system for locking a first edge of a first floor panel to a second edge of an identical second floor panel, the mechanical locking system comprising: a tongue and groove on the first edge and the second edge forming a first mechanical connection locking the first and second edges to each other in a first direction at right angles to a principal plane of the panels; a locking device arranged on an underside of the first and the second edges, the locking device forming a second mechanical connection locking the first and the second edges to each other in a second direction parallel to the principal plane and at right angles to the edges; the locking device including a locking groove which extends parallel to and spaced from the second edge, the l
