Method for dosing liquid reducing agent in exhaust system of internal combustion engine, involves conveying reducing agent from dosing pump to dosing valve in rapid, sequential doses in chronologically separated, individual conveyance steps

摘要

#CMT# #/CMT# The method involves conveying a reducing agent from a dosing pump (8) to a dosing valve (10) in rapid, sequential doses in chronologically separated, individual conveyance steps to a dosing valve. The individual dosing quantities of an individual dosing process by reducing agent that are delivered in the dosing process takes place directly after the individual dosing process. The individual dosing quantities are firmly adjusted oppositively in another individual dosing process in the exhaust system. #CMT# : #/CMT# An independent claim is also included for a dosing system for dosing a liquid reducing agent in an exhaust system of an internal combustion engine. #CMT#USE : #/CMT# Method for dosing a liquid reducing agent in an exhaust system of an internal combustion engine. #CMT#ADVANTAGE : #/CMT# The individual dosing quantities of an individual dosing process by reducing agent that are delivered in the dosing process takes place directly after the individual dosing process, and thus ensures to increase the dosing quality by a high ratio in simple manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic block diagram of an internal combustion engine, which assigns an exhaust system and a dosing system for a reducing agent. 1 : Internal combustion engine 2 : Dosing system 4 : Exhaust system 8 : Dosing pump 10 : Dosing valve.
