Johnson Matthey's ACCRT (Advanced CCRT) system, the second generation benchmark CCRT filter technology for 2.5g NOx EGR and non-EGR engines, has been verified by the California Air Resources Board (CARB) for reducing PM by more than 90%, while meeting CARB's stringent NO2 slip requirements.
• ACCRT system uses three catalytic formulas engineered for optimum performance
• Upstream, JM oxidation catalyst coated on a flow-through substrate optimizes conditions for second, downstream wall-flow filter to burn off PM
• Third catalyst, an NO2 decomposition catalyst, reduces NO2
