Atomization mechanism for treatment of exhaust gases of diesel engines with treatment medium consisting of urea and water solution in a certain proportion which is sputtered through nozzle of injector at predetermined pressure

摘要

The atomization mechanism has housing (1) which has annular space (12) and axial passage (5) through which exhaust treatment medium is made to pass. The linking up valve (9) connects the medium to the centrifugal chamber (27) and to the nozzle bore (29) for splashing on the exhaust gas stream. The valve seat (25) in the valve body (16) is for axial adjustment and regulating the atomization.
