Restart NOx emission suppression material (SRR-MIX*)

To suppress nitrogen oxide (NOx) at engine restart after idling stop, aim at enhance NOx purification reactions, we investigate the composite zirconium (Zr) oxide which is a carrier for rhodium (Rh) has been carried out. Based on the results, we have been developing the washcoat material (SRR-MIX) which enhances a steam reforming reactions and works specially for Nox under engine stop/go conditions. * SRR-MIX: Abbreviation for Steam Reforming Reaction-Mix-Material
