Selective Catalytic Reduction (SCRoF)
During the combustion process inside a diesel engine, the chemical energy is transformed into mechanical energy. Due to the chemistry of combustion, several toxic substances are produced, the most harmful being Nitrogen Oxides (NOx) and Particulate Matter (PM). Selective Catalytic Reduction (SCR technology) is designed to permit nitrogen oxide (reducing the possibility of reactions in an oxidizing atmosphere). SCR on filter (SCRoF) is an advanced active emissions control technology system that injects a liquid reductant agent through a special catalyst into the exhaust stream of a diesel engine. AdBlue® is a clear mixture of demineralized water and pure urea (32.5%) and is also referred to as Diesel Exhaust Fluid (DEF). It is designed to convert the emission of harmful nitrogen oxides from diesel vehicles to non-hazardous gases, in order to comply with more stringent emission standards. The new HI-eSCR2adopts SCR on filter (SCRoF) technology consisting of a ceramic substrate with alternatively closed channels and SCR coating. PM filtration is integrated onto the SCR system, enabling it to comply with both the NOx and PM requirements.
