[가솔린엔진부문] 이중관 배기매니폴드의 HC저감효과 및 열특성에 관한 연구 = A Study on the Reduction of HC and Heat Characteristics of the Dual Pipe Exhaust Manifold

다국어 초록 (Multilingual Abstract)

During cold-start period, the reduction of exhaust emissions is a challenging task. To decrease hannful gaseous substances such as HC it is necessary to realize a fast catalyst warm-up. In this study, the perfonnance of dual pipe exhaust system have been carried out through different test mode. From measurement of gas temperature and HC concentration the following conclusions were derived I) Compared with single pipe. dual pipe exhaust system remarkably increase temperature of exhaust gas going through M.C.C(Main Catalytic Converter)<br/>
2) W.C.C.(Warm-up Catalytic Converter) also decreases HC emission. To reduce HC emission, it is helpful to use W.C.C. as well as dual pipe exhaust system. 3) Using finite element method, it is shown that inner parts have much higher distribution of temperature than outer parts
