Fluid Injection System

Abstract

A fluid injection system having a line section in which an injection apparatus is arranged and having, arranged downstream thereof, an evaporator device to which there is assigned, downstream, a catalytic converter in which a fluid injected by the injection apparatus undergoes a catalytic reaction with the exhaust gas. At least one further injection apparatus is arranged in the line section.

1 .- 10 . (canceled) 
     
     
         11 . A fluid injection system comprising:
 a line section;   a first injection apparatus arranged in the line section and configured to inject a fluid; and   at least one further injection apparatus is arranged in the line section and configured to inject the fluid,   wherein the line section is configured to have a downstream evaporator device and downstream thereof a catalytic converter in which the fluid injected by the injection apparatuses undergoes a catalytic reaction with exhaust gas.   
     
     
         12 . The fluid injection system as claimed in  claim 11 , wherein at most four injection apparatuses are arranged in the line section. 
     
     
         13 . The fluid injection system as claimed in  claim 12 , wherein the injection apparatuses are arranged symmetrically on a circumference of the line section. 
     
     
         14 . The fluid injection system as claimed in  claim 12 , wherein the line section comprises multiple line element segments, wherein at least one injection apparatus is arranged in each line element. 
     
     
         15 . The fluid injection system as claimed in  claim 11 , wherein the injection apparatuses are arranged at a same level in a flow direction. 
     
     
         16 . The fluid injection system as claimed in at  claim 11 , wherein at least one injection apparatus is arranged downstream of the at least one further injection apparatus. 
     
     
         17 . The fluid injection system as claimed in  claim 16 , wherein a spacing of the injection apparatuses in a flow direction is between at least one of:
 0.1 to 1.5 times a diameter of the line section,   0.2 to 1.0 times the diameter of the line section, and   0.4 to 0.8 times the diameter of the line section.   
     
     
         18 . The fluid injection system as claimed  claim 12 , wherein the injection apparatuses are arranged at a same angle with respect to a longitudinal axis of the line section. 
     
     
         19 . The fluid injection system as claimed in  claim 12 , wherein at least one injection apparatus is arranged at a different angle with respect to a longitudinal axis of the line section than another injection apparatus. 
     
     
         20 . The fluid injection system as claimed in  claim 12 , wherein at least one injection apparatus generates a different spray pattern than at least one other injection apparatus.
