| Abstract(J) | エンジンが高負荷運転する時は，大流量のため触媒での排出ガスの流速が大きく，浄化性能が低下する．本研究ではエンジンの排気脈動に注目し，流速変動を低減することで浄化性能を向上させた．触媒位置での速度変動の制御は，触媒より下流に搭載されたマフラの内部構造を変更することで行った． Translation |
| Abstract(E) | When the engine operates under high load, the large exhaust flow causes high gas velocities within the catalyst, reducing its purification performance. In this study, the pulsation of the engine exhaust was investigated, and purification was improved by reducing fluctuations in flow velocity. Control of the velocity fluctuations within the catalyst was achieved by altering the internal structure of the muffler mounted downstream of the catalyst. |
