[가솔린엔진부문] 촉매변환기내 유동분포 개선을 위한 형상 최적화 = Geometry Optimization of Catalytic Converter for Improved Flow Distribution

다국어 초록 (Multilingual Abstract)

Performance improvement and longer service life of automotive catalytic convener can be achieved by improving the flow distribution of exhaust gas through a catalytic convener. Several design parameters which include the geometry of diffuser inlet and inlet diffuser, relative position of inlet pipe and monolith centers were investigated against their effects on flow uniformity in the convener. The flow distribution was improved by the geometry optimization of exhaust system under limited conditions.
