- NOx存储还原催化剂
- Lean NOx Trap(LNT)
LNT适用于国Ⅵ以上轻型柴油机/车,其工作原理是通过调整发动机燃烧条件切换贫富燃环境,该催化剂分别在贫燃条件下氧化NO并存储NOx,在富燃条件下利用尾气中的H2、CO和HC等还原性物质还原催化剂释放的NOx。
LNT is fit for light diesel vehicles to meet China-Ⅵ emission regulation.The principle is to change burnning condition according to parameter setting.While lean-burnning,NO can be oxidized to NOx which stored by LNT.Then in oxygen-enriched combustion,LNT releases and reduces the stored NOx with H2,CO and HC in exhuast.
