| Abstract(J) | ディーゼル乗用車では冷間始動時のNOx浄化率向上のため，電気ヒータ(EH;Electric Heater)の採用例がみられる．ここでは，大型商用車用ディーゼル機関に搭載位置の異なる 2つのEHを用いた場合の準定常運転とWHTCモード運転にて，NOx浄化触媒前の排気温度の変化を調査し，1次元シミュレーションに反映させてEHのNOx浄化率改善効果を推定した． Translation |
| Abstract(E) | In this study, the characteristics of exhaust gas temperature rise for different EH install positions was evaluated by experiments. In addition, the effect of EH install positions on the NOx purification rate in WHTC-cold test cycle was evaluated by simulation. As a result, when heated with EH installed on the front of SCR, exhaust gas reached target temperature rapidly, and therefore higher NOx purification rate was obtained. Also, it was suggested that electricity supplied to EH until the exhaust gas reach target temperature can be compensated by the power recovered with braking regeneration by combining with high-efficient braking regenerative systems. |
