Method for dosing an urea based reducing agent into a gas exhaust stream |
摘要 |
The present invention provides for a method for dosing an urea -based reducing agent into a exhaust gas stream generated from a combustion engine and addressed to an aftertreatment system, e.g. SCR or SCRT system. According to the method of the invention the gas exhaust stream is conveyed into a dosing housing which develops along a longitudinal axis. In particular the gas is conveyed by generating an annular inlet jet inclined with respect of said axis. The urea-based reducing agent is injected by generating, inside the housing, an urea -based reducing agent spray which is preferably coaxial to said axis of the housing. |
