NOx storage reduction type 3-way catalyst

With the tightening of regulations on CO₂ (carbon dioxide) and NOx (nitrogen oxides) in various countries, we focused on the fact that NOx can be stored. Based on this, we worked on the development of technology to optimize the arrangement of substances with NOx storage function, and precious metals with catalytic function. This enabled "NOx storage" and "optimization reduction function of stored NOx", and succeeded in achieving both improved fuel efficiency and NOx purification. This technology was highly acclaimed, and won numerous awards, including the Toyota Motor Corporation Technology & Development Award.
