Since 2008, the application of Selective Catalytic Reduction (SCR) technology on passenger vehicles in US and Europe ensures an efficient Nitrogen Oxides (NOx) after-treatment to meet Tier 2 Bin 5 emissions regulation requirements.
The first generation of INERGY's DINOx SCR technology is a system which integrates all key functions into a plastic urea tank:
It also offers further options such as temperature and fluid level sensors, according to OEMs' specifications and demand.
This system is available as a standard module for all passenger car SCR applications and is compatible with all urea injectors on the market.
Constantly improving its SCR expertise, INERGY launched DINOx Premium, a cost effective AdBlue® storage and delivery system. With a more compact and economical design, DINOx Premium:
 - integrates all system functions into the DINOx AdBlue® Delivery Module (ADM) and offers additional features such as quality detection and enhanced heating.
- optimises SCR system control with the DINOx Control Unit (DCU), a dedicated electronic controller containing a full set of SCR system control hardware and strategies with the aim to reduce power consumption and improve system performance. Upon request the control unit can be de-contented for optimal integration in the OEM's specific electronic architecture.
NOx reduction reaction
On Clean Diesel vehicles, an aqueous solution of urea, such as AdBlue® is sprayed into the exhaust gas. This creates a chemical transformation by hydrolysis: an atomization and decomposition of urea towards ammonia (NH3) which reacts with NOx inside of the catalytic converter to form inert nitrogen (N2) and water vapor, drastically reducing NOx emissions. |  |  |
Already chosen by OEMs for serial production, INERGY's DINOx Premium will equip several vehicle models by the end of 2011 in Europe and in the USA.
And because INERGY is a world leader in SCR applications for passenger cars and light commercial vehicles, it is active in several international working groups on SCR technology, creating worldwide standards for this technology.
Through its compact and fexible design, DINOx Premium revolutionises the affordability of SCR systems for diesel vehicles. | |  |
