Device for the post-treatment of exhaust gases of an internal combustion engine

摘要: The invention relates to a device for the post-treatment of exhaust gases an internal combustion engine, using reductant that is be introduced into gases, in particular urea or urea-water solution, comprising mixing chamber, which stored can via conduit and compressed air create reductant-air mixture. provided with elements preventing reflux mixture from chamber conduit. Said have spring-loaded (112, 114) sealing hose (110). arrangement ensures connectable system reliably sealed against corrosive reductant.
