| Abstract(J) | EGR配管に生成するデポジットは，ある量で飽和することが報告されている．これまで我々のグループでは，デポジットの生成メカニズムに関する検討を行ってきたが，デポジットの生成量が飽和し，見かけ上一定になるメカニズムは検討できていない．本報告では，これまでの明らかにした生成メカニズムを基に，実験エンジンの排出ガスを用いた実験から，デポジットの生成量が飽和するメカニズムを検討した． Translation |
| Abstract(E) | To reduce NOx emitted from diesel engines, EGR operating condition is required to be expanded into cold start conditions. However, the deposits are formed and saturated in EGR system, when the EGR was used under the relatively cold temperature condition, which are serious problems. Although the deposit formation mechanism has been studied to investigate the way of the reduction of the deposits, the deposit saturation mechanism has not been examined. In this study, the saturation mechanism of deposit was evaluated. As a result, it is found EGR gastemperature and flow rate played important roles in the deposit saturation. |
