Device for injecting fluid into exhaust line of internal combustion engine, has two electrical measurement points that are provided on fluid line for measuring electrical conductivity of fluid in fluid line

摘要

#CMT# #/CMT# The device has an injection module (2) for injecting a fluid from a fluid line (4) into an exhaust line (5). Two electrical measurement points are provided on the fluid line for measuring the electrical conductivity of the fluid in the fluid line. The electrical measuring point is designed as a screw, and is attached to wall (8) of the fluid conduit. An O-ring is arranged between the screw and the wall of the fluid line. #CMT# : #/CMT# An independent claim is included for method for injecting fluid into exhaust line of internal combustion engine. #CMT#USE : #/CMT# Device for injecting fluid into exhaust line of internal combustion engine. #CMT#ADVANTAGE : #/CMT# The quality of the fluid injected into the exhaust line is enhanced so that measurement of conductivity is performed precisely and reliably, thus false refueling resulting damages of the exhaust gas reduction system is prevented. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawings show a schematic view of the injection system, and a sectional view of the fluid conduit. 1 : Fluid tank 2 : Injection module 4 : Fluid line 5 : Exhaust line 8 : Wall.
