| Abstract(J) | 還元剤濃度を能動的に制御し，特に低温における浄化率向上を達成した．さらに，詳細な表面反応を考慮した数値熱流体コードにより触媒層の気孔率や担持量を検討し，新しい２種類の触媒を試作した．同触媒をディーゼルエンジンに搭載し還元剤の能動的制御と組み合わせることでより高い浄化率が得られることを実験的に示した． Translation |
| Abstract(E) | Active control of the reductant concentration improved the NOx conversion rate, especially at low temperatures. Furthermore, the porosity and loading of the catalyst layer were investigated using a numerical thermo-dynamic code combined with detailed surface reactions to design two new catalysts which were tested on a diesel engine. As a result, higher purification rates could be achieved in combination with active control of the reductant. |
