Development of the Design Methodology for a New De-NOx System
The design methodology for a new de-NOx system “DiAir” has been developed in this study. Based on the NOx reduction mechanism, the amplitude of hydrocarbon (HC) concentration and the uniformity of exhaust gas and HC at inlet of the catalyst have been derived as the key factors to achieve high de-NOx...

| description | The design methodology for a new de-NOx system “DiAir” has been developed in this study. Based on the NOx reduction mechanism, the amplitude of hydrocarbon (HC) concentration and the uniformity of exhaust gas and HC at inlet of the catalyst have been derived as the key factors to achieve high de-NOx performance. The improvement method of de-NOx performance in exhaust layouts for various vehicles has been clarified with improving the shape of the exhaust pipe and the configuration of the injector on engine test and CFD analysis. |
