| Abstract(J) | ディーゼル車のNOx排出量削減が求められている．本研究では1Hz毎に行われる尿素の定常噴射と，定常噴射に任意のDuty比で尿素噴射の有無を制御するパルス噴射を行い，尿素SCR触媒のNOx浄化性能変化を調査した．尿素の噴射方法がNOx浄化性能に与える影響を調査するため，計算モデルを作成した． Translation |
| Abstract(E) | There is a growing need to reduce NOx emissions from diesel vehicles. In this study, the NOx conversion performance of a urea SCR catalyst was investigated by comparing steady urea injection at 1 Hz intervals with pulse injection, in which the presence or absence of urea injection was controlled at an arbitrary duty cycle. A computational model was developed to investigate the effect of urea injection methods on NOx conversion performance. |
