APPARATUS FOR MIXING A LIQUID MEDIUM INTO A GASEOUS MEDIUM

摘要

The invention relates to an apparatus for mixing liquid medium into a gaseous medium flowing through an exhaust pipe (10) from an internal combustion engine. The liquid medium is supplied to the exhaust pipe with varied mass flow via an injector nozzle (11) directed into the exhaust pipe. The exhaust pipe (10) has a mixer (16) placed downstream of the injector nozzle and a flow path (18) disposed parallel with the mixer and extending through a perforated surface (19).
