Diesel exhaust fluid dosing system for diesel engine aftertreatment module

摘要

A dosing system for dosing diesel exhaust fluid (DEF) into an inlet of a selective catalytic reduction (SCR) aftertreatment module of a diesel engine is described. The dosing system may comprise a DEF supply line configured to deliver the DEF from a pump to a first injector and a second injector at the inlet. The DEF supply line may include a tri-axis connector configured to split the DEF from the pump into two portions each exiting one of a first outlet port and a second outlet port, a first delivery conduit configured to deliver the DEF exiting the first outlet port to the first injector, and a second delivery conduit configured to deliver the DEF exiting the second outlet port to the second injector. The first injector and the second injector may dose the same quantity of the DEF into the inlet of the aftertreatment module.
