| Abstract(J) | 100％電動駆動ハイブリッド車でのエンジン再始動時の排出ガス低減を検討した．多段化した三元触媒システムでの各触媒の酸素吸蔵量の制御に着目し，触媒間に酸素センサを配置し目標空燃比を最適化した結果，前段触媒での迅速な酸素量消費と後段触媒での酸素量保持によりHC，NOx浄化率は大きく向上した． Translation |
| Abstract(E) | Reduction of exhaust gas in engine restart of 100% Electric Drive HEV was examined. Focusing on the control of the amount of oxygen absorbed by each catalyst in the multi-stage three-way catalyst system, oxygen sensors were placed between the catalysts to optimize the target air-fuel ratio. As a result, the HC and NOx conversion rates were greatly improved by the rapid consumption of oxygen in the front-stage catalyst and the retention of oxygen in the post-stage catalyst. |
