Abstract
The NOx emission aftertreatment of compressed ignition engines has always been a point of concern. The legislative emission limits for heavy duty vehicles constantly tighten the requirements for emissions of NOx. Nowadays it is believed that the most effective and reliable method of NOx reduction is a Selective Catalytic Reduction (SCR) system. The reducing agent of the system is ammonia, delivered and stored on a vehicle as Adblue, an aqueous urea solution. As all catalyst based clean-up systems, SCR activates only when a certain temperature is achieved. Nevertheless, once the system is started, the reduction efficiency of up to 99% can be achieved.
