Description
본 발명은 웜 업 촉매컨버터와 터보차저의 연결구조에 관한 것으로, 특히 웜 업 촉매컨버터의 결합 플랜지면에 내측으로 파여진 결합홈이 형성됨과 더불어 터보차저의 결합 플랜지면에는 결합홈에 삽입되어 결합되는 돌출턱을 형성하여 터보차저와 웜 업 촉매컨버터 사이의 기밀성을 향상시키도록 한 웜 업 촉매컨버터와 터보차저의 연결구조에 관한 것이다.The present invention relates to a connection structure between a warm-up catalytic converter and a turbocharger. In particular, a coupling groove is formed in the coupling flange surface of the warm-up catalytic converter and is inserted into the coupling groove on the coupling flange surface of the turbocharger. The present invention relates to a connection structure of a warm-up catalytic converter and a turbocharger to improve airtightness between the turbocharger and the warm-up catalytic converter by forming a protruding jaw.
종래 차량의 배기가스에 포함된 유해가스를 정화시키기 위해 후처리장치로서 촉매컨버터가 널리 사용되고 있다. BACKGROUND ART A catalytic converter is widely used as a post-treatment device to purify harmful gas contained in exhaust gas of a vehicle.
이러한 촉매컨버터는 언더 플로어 촉매컨버터(UCC; Under-floor Catalytic Converter)외에 엔진의 배기매니폴드에 바로 장착되는 웜 업 촉매컨버터 등이 있다.Such catalytic converters include a warm-up catalytic converter, which is mounted directly to an exhaust manifold of an engine, in addition to an under-floor catalytic converter (UCC).
상기 웜 업 촉매컨버터는 배기매니폴드의 입구부에 연결된 터보차저의 출구부에 통상적으로 직결되어, 상기 터보차저의 출구부를 통해 빠져나오는 배기가스가 바로 웜 업 촉매컨버터로 유입되게 된다.The warm-up catalytic converter is typically directly connected to the outlet of the turbocharger connected to the inlet of the exhaust manifold, so that the exhaust gas exiting through the outlet of the turbocharger flows directly into the warm-up catalytic converter.
상기와 같이 웜 엄 촉매컨버터가 터보차저에 직결됨에 따라 이들 사이의 직결부에 배기가스의 누출을 방지하도록 개스킷이 적용된다.As described above, as the worm Um catalytic converter is directly connected to the turbocharger, a gasket is applied to prevent direct leakage of exhaust gas between the direct connection therebetween.
즉 웜 업 촉매컨버터의 선단면에는 확장된 형태의 결합 플랜지가 형성되고, 상기 터보차저의 후단면에는 상기 결합 플랜지에 대응하는 결합 플랜지가 확장된 형태로 형성되어, 상기 결합 플랜지들이 서로 체결볼트로 체결되어 웜 업 촉매컨버터가 터보차저에 직결된다.That is, an extended coupling flange is formed on the front end face of the warm-up catalytic converter, and a coupling flange corresponding to the coupling flange is extended on the rear end surface of the turbocharger, and the coupling flanges are fastened to each other. The worm-up catalytic converter is connected directly to the turbocharger.
그리고 상기 결합 플랜지들 사이에는 상기 개스킷이 개재되어 결합 플랜지들 사이로 배기가스의 누출을 방지하게 된다.The gasket is interposed between the coupling flanges to prevent the leakage of exhaust gas between the coupling flanges.
그런데 상기와 결합 플랜지들 사이에 개스킷이 개재되어 체결된 상태에서 엔진의 진동이나 충격이 배기매니폴드를 통해 터보차저와 웜 업 촉매컨버터에 가해지면 결합 플랜지들을 체결하고 있는 체결볼트가 풀리면서 그 조임력이 약화되어 결합 플랜지들 사이로 배기가스가 누출되고, 이렇게 누출된 배기가스는 상기 개스킷을 소손하게 되어, 개스킷이 본래의 기능을 다하지 못할 뿐만 아니라 각 결합 플랜지들도 변형되는 결점이 있었다.However, when the vibration or shock of the engine is applied to the turbocharger and the warm-up catalytic converter through the exhaust manifold while the gasket is interposed between the coupling flanges and the coupling flanges, the fastening bolts that fasten the coupling flanges are released, This weakened and exhaust gas leaks between the joining flanges, and the leaked exhaust gas burns the gasket, so that the gasket does not perform its original function but also the respective joining flanges are deformed.
이에 본 발명은 상기한 사정을 감안하여 안출된 것으로, 웜 업 촉매컨버터의 결합 플랜지와 터보차저의 결합 플랜지에 중첩구간을 형성하여 배기가스의 누출을 효과적으로 방지함과 더불어 개스킷이 배기가스의 고온에 직접 노출되지 않게 해서 개스킷의 내구성을 향상시키도록 한 웜 업 촉매컨버터와 터보차저의 연결구조를 제 공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above-described circumstances, and overlapping sections are formed on the coupling flange of the warm-up catalytic converter and the coupling flange of the turbocharger to effectively prevent the leakage of exhaust gas and to prevent the gasket from being exposed to the high temperature of the exhaust gas. Its purpose is to provide a connection structure between a warm-up catalytic converter and a turbocharger that prevents direct exposure to improve the durability of the gasket.
상기와 같은 목적을 달성하기 위한 본 발명은, 웜 업 촉매컨버터의 결합 플랜지의 상부에는 내측으로 파여진 형태의 결합홈과 하부에는 축방향으로 돌출한 돌출턱이 각각 형성되고, 상기 결합 플랜지에 체결되는 터보차저의 결합 플랜지의 상부에는 상기 결합홈에 삽입되도록 축방향으로 돌출한 돌출턱이 형성됨과 더불어 하부에는 상기 웜 업 촉매컨버터의 돌출턱이 삽입되어 결합되도록 내측으로 파여진 형태의 결합홈이 형성되며, 상기 웜 업 촉매컨버터의 결합홈과 터보차저의 돌출턱 사이에는 개스킷이 개재된다.In order to achieve the above object, the present invention provides a coupling groove of the inner side of the coupling flange of the warm-up catalytic converter and a protrusion projection protruding in the axial direction, respectively, and fastening to the coupling flange. The upper part of the coupling flange of the turbocharger is formed with a protruding jaw protruding in the axial direction so as to be inserted into the engaging groove, and the lower part of the engaging groove of the inner shape so that the protruding jaw of the warm-up catalytic converter is inserted into and coupled to the lower part of the turbocharger. The gasket is interposed between the coupling groove of the warm-up catalytic converter and the protrusion jaw of the turbocharger.
바람직하기로는 상기 웜 업 촉매컨버터의 돌출턱과 상기 터보차저의 돌출턱은 일부가 중첩되게 배치되는 것을 특징으로 한다.Preferably, the protrusion jaw of the warm-up catalytic converter and the protrusion jaw of the turbocharger are partially overlapped.
상기 웜 업 촉매컨버터의 돌출턱과 대향하는 터보차저의 결합홈의 대향면 사이에는 소정 크기의 갭이 형성되는 것을 특징으로 한다.A gap of a predetermined size is formed between the protruding jaw of the warm-up catalytic converter and the opposing surface of the coupling groove of the turbocharger.
