A new Approach in AdBlue Dosing to Improve Performance and Durability of SCR Systems for the Use in Passenger Cars up to Heavy Duty Vehicles 2011-01-2095
SCR technology is becoming more and more important for the
segment of diesel-driven passenger cars. Due to space and
functional demands the dependency of SCR performance on a uniform
supply of ammonia into the catalytic substrates is highly
Both an even distribution of the AdBlue® spray and a completed
evaporation and decomposition of the droplets are the key to
achieve the desired ammonia spread.
Evaluation of the influence of spray quality on the AdBlue®
decomposition and catalyst performance are leading to a new
approach in dosing, using a special nozzle and air-supply strategy.
The resulting new technology is evaluated and compared to the state
of the art.
