Dosing module for introducing reducing agent in exhaust pipe of internal combustion engine of vehicle, has metering valve inserted into housing, and cool air ribs interconnected with conveying device over pressure line

摘要

#CMT# #/CMT# The dosing module (5) has a metering valve (4) inserted into a housing (6), and cool air ribs (9) interconnected with a conveying device (1) over a pressure line (3). The housing is surrounded in the region of the cool air ribs by a cool air guidance channel (10). The cool air guidance channel is coupled to a cool air conveying device. The cool air conveying device is a fan. #CMT#USE : #/CMT# Dosing module for introducing a reducing agent in an exhaust pipe of an internal combustion engine of a vehicle, particularly comercial vehicle. #CMT#ADVANTAGE : #/CMT# The dosing module has a metering valve inserted into a housing, and cool air ribs interconnected with a conveying device over a pressure line, where the housing is surrounded in the region of the cool air ribs by a cool air guidance channel, and thus ensures an inexpensive dosing module. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross-sectional view of a dosing module. 1 : Conveying device 3 : Pressure line 4 : Metering valve 5 : Dosing module 6 : Housing 9 : Cool air ribs 10 : Cool air guidance channel.
