Lean NOx Trap technology is a promising method to reduce nitrogen oxides in lean exhaust condition. The technology operates by storing NOx during lean exhaust conditions and then, under rich exhaust conditions, releasing and reducing the stored NOx to nitrogen. The reduction process is called regeneration and typically involves some additional fuel use or fuel penalty. In this study injection timing and injection quantity are optimized for minimize fuel penalty and maximize NOx conversion efficiency.
