Authors Abstract
Content
This paper describes a newly developed NOx trap catalyst that achieves cleaner exhaust gas using much smaller quantities of precious metals. The precious metal loading of this NOx trap catalyst has been halved by developing a technique for inhibiting precious metal sintering even under exposure to high temperature exhaust gas and a trap material with improved catalyst functions at low temperature. This NOx trap catalyst is used on the Nissan X-TRAIL fitted with a diesel engine, which was the first vehicle to comply with Japan's Post New Long term Exhaust Emission Regulations.
