Nissan has developed high-performance catalyst technology to meet the state of California's standard for super-ultra-low emission vehicles (SULEVs), equivalent to the Tier2Bin2 emission requirements.
Features
HC, a regulated substance is effectively used to generate a chemical reaction of NOx reduction. This helps realize highly efficient removal of HC and NOx.
- Distribution of catalyst components has been optimized to realize highly efficient chemical reaction of HC and NOx reduction.
- Advanced distribution/coating technology for each component has been used to efficiently trap HC while maintaining the high NOx reduction performance.
Structure
Operation Principle
While conventional NOx-trap catalysts reduced only NOx under the rich condition, the new catalyst has an additional HC-trap layer to efficiently use HC, a regulated substance, for generating a chemical reaction of NOx reduction. This helps realize highly efficient removal of HC and NOx even if under the rich conditon.
