Abstract

NOx reduction mechanism and requirements for high NOx reduction efficiency in a urea SCR system at transient conditions with low exhaust gas temperature were investigated by using a four liters multi-cylinder diesel engine. NOx can be significantly reduced by adjusting mode-overall SCR inlet NO₂/NOx ratio at 0.5±0.1 while adopting NH3 adsorption quantity control. It has been shown that ammonium nitrate (NH₄NO₃) plays an important role in enhancing the Fast SCR reaction at transient low exhaust gas temperature conditions.
